Transmission Flush

Posts Tagged ‘Check’

The longevity of a vehicle has a lot to do with how the vehicle is maintained by the owner. There are many basic car care requirements that should be performed on a regular basis. Checking your brake fluid is one of these basic tasks that tend to get overlooked. It’s a good idea to schedule it into your list of maintenance like oil changes and transmission checks. Checking the brake fluid is pretty easy. It just requires a few minutes of your time and a little patience.

Almost all basic car maintenance should be started with a cool engine so let it sit a while after you turn the car off. Safety is important and should always come first no matter what job you are doing. When you start out right, you are ensuring success with little chance of mishap.

In order to check your brake fluid you will need to look under the hood towards the back of the engine. It is usually on the driver’s side so check there first. If you know what you are looking for then finding it should be no problem. It doesn’t hurt to ask for help though so feel free to get a friend or family member to assist you.

You need to locate the master brake cylinder where the brake fluid is held. It is a small piece of metal that is usually rectangular in shape. It is basically a plastic reservoir and there will be a rubber cap on top of it. It should be pretty easy to identify. If you’re not quite sure if you have found it, double check by using photos in the owner’s manual that comes with your vehicle.

On most new vehicles the reservoir is easily see through so that you can see the fluid level without having to open the cap. If it’s not see through then you will have to take the cap off to look inside. The line will indicate if the fluid is too low or not. You can decide if you want to top it up yourself or take it to a professional.

It’s not all that difficult to refill the brake fluid to the full line but some people are not comfortable with that. If you wish, ask your mechanic to show you how to do it so you know for certain that you’re doing it right. Most mechanics will be happy to show you something like this for your own peace of mind. It never hurts to ask if you are unsure about something. It certainly is better to be safe than sorry.

Always read your vehicle’s manual to determine the appropriate type of brake fluid for your car. You must use the one specified or you could put your car in an unnecessarily compromising position. Follow all instructions regarding your car’s well being and maintenance. It is essential to the proper running condition of your car as well as your own personal safety. Where safety is concerned, there is never room for neglect.

The first most importantly thing to do is ask the salesperson for the used car history records. By doing this procedure may save you some time and money. If the used car history report shows that the car in fact was a rental vehicle or has been involved in an accident, there is no point to even looking at it any further recommended. Ask the previous owner or salesperson if any repair has been done to the transmission. If the automatic transmission has already been rebuilt, abstain from buying the car. By saying that… not suggesting that all rebuilt transmissions will have problems but in some cases they work even better than before. The problem is that not all transmission shops can do equally the same high quality job. And since there is no way to verify if it was rebuilt properly or not, it’s better not to take chances. Another thing to be concern about is, ask if the used car you are looking to buy was not used for any towing purposes. Many vehicles that have a towed history like an example towing a trailer. Have much greater risk of having a worn out transmission because of the use for towing that can put a sustainable amount of strain on the transmission over time.

How To Check A Automatic Transmission

You should first get started by checking the transmission fluid level and condition.
With the engine idling, transmission in “Park” (some cars may have different procedures, refer to owner’s manual if needed) remove the automatic transmission dipstick and wipe it off with a clean cloth. Then insert it back in and pull it out again. Check the fluid level, low level may indicate a transmission leak. Pay close attention at the fluid very closely. It helps to drip the fluid on a white paper towel to be able to see fluid condition. The fluid on the paper towel should be clean and transparent, without any metal filings or black flakes. New fluid usually comes out red. Over the time in use it become more of a brownish of color, but it shouldn’t be black.
Try to smell the fluid. It should not have a burnt smell.
It may seem to be difficult to tell at first, but after you check a few similar cars, you’ll be able to pin point the difference with ease.
If you discover that the transmission fluid is too dirty or black, or smells burnt, avoid buying such a car.
Keep in mind, however, that some modern cars simply don’t have the transmission dipstick and require special procedures performed in a shop to check the fluid level. In this case, the only way to check it is by doing a test drive.

Automatic Transmission Indications Of Possible Transmission Problems Overview

One of the indications of a transmission problem is delayed engagement, when there is a long delay between the moment you shift the shifter into “D” (Drive) or “R” (Reverse) and the moment the transmission kicks in.
It’s easier to note delayed engagement after a car was sitting for a while: With the transmission in “P” (Park) start the engine, and wait until the engine rpm has reduced to normal level (650 – 850 rpm).
With your foot holding down the brake pedal, shift to the “D” (Drive) position. Almost immediately the transmission should engage – it feels like the car wants to creep forward. This should happen very smoothly, without a strong jerk or clunk.
Shift to “N” (Neutral), and the transmission should disengage. Now, still holding the brakes, shift to the “R” (Reverse) position. Again, the transmission kicks in almost immediately – you will feel the car wants to creep backward. This also should be very smooth, without a jerk or clunk.
Now, still holding the brake pedal down, try to shift from D to R and back. There should be no strong jerk or clunk.
If there is a notable long delay (more than 1 seconds) between the moment you shift and the moment the transmission kicks in, such a transmission might be either too worn or has some problem.
If you feel a strong jerk or clunk while shifting, the car may have a transmission problem, avoid such a car.

Now it’s time to test drive the car.

With the shifter in “D” (Drive) position drive gently, with smooth and gradual acceleration. Until the vehicle reaches a speed of 30-37 mph (50-60 km/h) or you should feel the gears shifting at least twice (from first to second, and from second to third gear).
All shifts should be done very smoothly, without jerks or slipping.
You should be able to feel when the transmission shifts by the slight change in the engine tone or change in engine rpm. If the transmission is severely worn it may shift with quite a strong jerk, shudder or a delay (especially from first to second gear).
Driving at a speed of 25-30 mph (40-50 km/h) if you press down the accelerator pedal for a few seconds, you should feel downshifting to the lower gear, if the automatic transmission works properly.

The next step: check overdrive.

While driving at 60-70 km/h or 35-45 mph on a level road, without using the accelerator, switch overdrive ON. You should feel an up shifting to the next speed. Switch it to “OFF,” and you should feel a downshifting.
Another thing to watch out for that may indicate the transmission has a problem is the slipping. When the transmission is excessively worn it may slip – which means you press the accelerator, the engine rpm increases but the speed remains the same.

While during a test drive you feel any problems such as the transmission seems to be slipping or shifts with a jerk or shudder or if the transmission got stuck in some gear, or has trouble shifting into a particular gear (for example, from second to third), You should avoid buying such a car.
Always try to test drive the car as long as possible. Often the transmission may work well when it’s cold but when it’s warmed up it starts giving troubles or vice versa. So, it is better to spend more time checking the transmission thoroughly than later repairing it at your expense. Normally there should be no shudder, no noises or any kind of strong jerks at any speed and at any engine temperatures while any shifting is going on. If the salesperson tells you that the jerks or shudder or any other abnormal transmission behavior is “normal” for this car or it’s just because the car is cold or anything alike…, don’t trust them. If the “check engine” and, or a flashing overdrive light comes on while driving, have the vehicle inspected with a certified mechanic before buying a vehicle.

How To Check A Manual Transmission

You should first check for oil leaks. There should absolutely not be any leaks.

Now, shift the transmission lever into neutral. Apply the parking brake. With the engine idling, press the clutch pedal all the way, hold it down, and listen for noises. Then release the pedal and listen for noises again. There should be no loud noises at either positions.
The next step will be to take the car for a test drive.
Try to drive the vehicle at different speeds in all gears, one by one. Every gear should shift smoothly and easily without any noises or jerks. While driving at the second or third gear, try to press down sharply on the accelerator pedal for an instance. The clutch should not slip.
If you feel any slipping (example like… the engine rpm increases but the speed remains the same), then the clutch most likely has to be replaced.
Try to drive with acceleration and deceleration there should be no grinding, whining or humming noise under any condition circumstances. All the gears should shift easily and noiselessly free.

It is always recommended that you check the car’s transmission fluid at least every month or any time that the transmission is not shifting smoothly. This is important because it will help in the optimization of the performance of many components of the car. It is advisable to look up the manual so as to determine the intervals that you are required to change the fluid. Therefore to change your transmission fluid, consider the following steps.  

You should start by first parking the car on a level ground. This should then be followed by starting up the engine and then the gear should be left on a neutral or park. You should then leave the engine to warm up. It is advisable to leave the engine running all through this process unless the manual states otherwise. You should then get the dipstick from the back of the engine. The dipstick resembles the engine dipstick even though it is normally shorter.  

The dipstick should then be pulled out and removed completely. This may take a long time since the dipstick is long. After this, the dipstick should be wiped out with a rag then replaced back into the engine. It should then be pushed all the way into the engine and removed again. You should then examine the tip of the dipstick. This should enable you to determine if there are two different full markings. Normally the dipstick shows two markings, one for the warm readings and the other one for the cold readings. You should check whether the transmission fluid comes up to the line marked full on the warm reading. If it does not, you should then add the transmission fluid. 

It is advisable to add the transmission fluid to the hole where the dipstick came from. A funnel with a long narrow neck will be useful in this task. It is recommended that you add only a small amount of the transmission fluid at a time and always remember to check the level using the dipstick every time. Be careful not to add too much as it may difficult to take it out. Once you are through, put back the dipstick.

The transmission fluid for lower mileage cars should be changed in at least every 25,000 miles. It is recommended that you maintain the transmission fluid early in the life of the vehicle. This is because changing the transmission fluid later on may cause some trouble to the car. Regularly servicing the vehicle will help to make its life expectancy longer, increase its performance and also make the shifting smoother.  

Higher mileage cars should have their transmission fluid changed in less than 80,000 miles. In case the transmission is not maintained, you should avoid replacing the fluid as well as the filter.  This is because at this time, the fluid will be dirty and gritty and this is important for providing the friction necessary for the worn out internal parts of the transmission. The transmission should be serviced regularly.

Of all components that a car needs to run smoothly, the transmission plays one of the biggest roles because it is what assists in gear shifting thus propelling a car accordingly. If not checked regularly, it could lead to car malfunction and expensive costs of repair. Transmission fluid just like oil needs to be checked regularly for appropriate maintenance of a car and this is normally done after every 25,000 miles driven. This fluid is a lubricant, viscous in nature and eases the movement of components within both manual and automatic transmission systems. It also goes further to assist in torque conversion, valve operation, and break friction.  

Most cars come with a dipstick, which is specifically made to check the levels of transmission fluid. It is usually a shorter stick than the one used to check oil levels and often has a red cap. To check the levels, remove the dipstick and wipe its shaft clean. Then dip it back in its compartment and pull it out again. The stick has two lines on it and the fluid level should lie between these two lines. After confirmation of the level of transmission fluid, wipe the stick with a white piece of fabric and this is done purposely to verify the fluid’s color. If it has a pinkish tint, then it is okay but if it has a dark hue then it is likely that the transmission has a problem. The smell has to be checked too and if the transmission fluid smells burnt or pungent then it should be changed as soon as possible. If the fluid is found to be below the recommended levels, then put a funnel over the opening for the dipstick and carefully direct the new fluid through. Check the level once more to find out if it is appropriate. Note that this procedure should be done when the car engine is off and cool. 

In vehicles with manual transmission, the contamination of the fluid is a major issue. This happens because of regular use of gears, synchronizers and bearings, which leads to corrosion of the metallic components. Residue particles eventually end up in the transmission fluid. When this happens, the fluid cannot work effectively as required and needs to be replaced. Transmission fluid for automatic transmission happens to be prone to contamination caused by excessive heat exposure during the transmission process. Because of this, the fluid loses a lot of its important lubricating ability and accumulates pollutants lowering the cars overall performance. Another scenario when the transmission fluid could be affected is when a vehicle sits idle for a long period. There is a possibility of metallic shavings making their way into the fluid therefore flushing out the old fluid is necessary. It is worth noting that the level of transmission fluid should be carried out when the car is on a level surface in order to get the correct readings. Regular checking of the transmission fluid is vital to ensure the car functions optimally. 

A car requires different fluids to run. Transmission fluid is one among the vital fluids that cars those that use both manual and automatic transmission require to run optimally. Transmission fluid is a slick lubricant that facilitates the smooth movement of parts when driving. The fluid also acts as a coolant and its viscous nature helps transmit engine power to the transmission. Moreover, the fluid is vital for gear lubrication, torque conversion, brake friction and valve operation. Transmission fluid should be changed after a given mileage usually as stated by the manufacturer.  However, if one buys purchases a car and they are not very certain of its history, checking the transmission fluid is the only way they can ensure that the transmission will run smoothly. Leaks may also necessitate the user to inspect transmission fluid levels. Although changing the fluid is best left to professional mechanics, checking the levels is easy and can be done from one’s home garage.

Most cars are equipped with dip sticks specifically used to check the oil and transmission fluid levels. The transmission dipstick is shorter than that used to check the engine oil level.  The person checking the fluid levels should first wipe the dipstick and then deep it into the engine compartment where the transmission fluid is held. After the dip and the subsequent confirmation of the level, one should wipe the dip stick on a white cloth specifically to check the color of the fluid. Ideally, fluid that has acquired a darkish tone either indicates issues with the transmission system, misuse of the vehicle or fluid that has run its course.   Unlike engine oil, the difference between low and high levels of the transmission fluid is usually a pint only.  Thus, it is vitally important that the person taking the transmission fluid levels take clear readings from the dipstick, which should guide them on whether to add, change or retain the current levels.

In manual cars, transmission fluid contamination is a significant issue and car owners have to regularly check for this. The constant use of gears, bearings and synchronizers during power transmission results in the eventual wear and tear of these metallic parts.  The released metal particles subsequently end up in the transmission fluid. Therefore this affects the ability of the fluid to effectively lubricate  and if a replacement of the contaminated  transmission fluid is  not carried out,  the  contaminants  eventually shortens the  lifespan of the  transmission  system as it hinders the proper lubrication of these parts.

The automatic transmission fluid however is prone to degradation, which occurs when the fluid breaks down due to exposure to the heat generated during transmission.  At such, the fluid looses some of its vital lubricating ability and eventually accumulates contaminants. Therefore, if it is not drained and changed out, it then shortens the performances of the transmission system. Constant inspection and change is advisable when the need arises.  This not only minimizes the trips to the mechanic, but also reduces the amount of funds used resolving transmission system problems.
