How To Change a Transmission Fluid Filter

Often times you tend to lose sight of changing your car's transmission fluid filter. When this happens, your transmission will go bad because it is clogged and unclean with dirt.  Fluid maintenance is therefore very important.  According to car makers the transmission fluid filter of your automobile must be replaced every two years or 30,000 miles. This will give additional transmission life and excellent transmission performance to your vehicle.

Below are the ways to replace your transmission fluid filter.

1.    Do the following safety precautions before you begin:

  • Read and follow each instruction heedfully to ensure that you fully comprehend them before you start.
  • Get your needed supplies and tools ready.
  • Do not forget every important instruction.
  • See the right repair manual for a more detailed and guided information for your specific type of vehicle.
  • Never try to work on an automobile that is supported by a jack alone instead make use of a jack stand to hold the car.

2.    Begin with the appropriate materials.  Also, buy a transmission filter and transmission fluid service kit. The kit contains the gasket, o ring, fluid and as well as the filter. Use the jack along with the jack stand to adequately elevate the car and to support it as well. Unfastened the drain bolts or loosen all except for one or two bolts and the tipping pan. Remove the fan as soon as the transmission is empty. Detach the o ring and the filter.

3.    Use shop toweling to cleanse the pan, gasket and the magnet as well. The old O ring must come out together with the worn-out filter. If you weren't able to draw out the worn O ring and filter, you may take it out by reaching within the valve body and clutch it out with a pick. There should be one seal only hence the new filter will not sit properly if you will leave the worn-out seal. Assemble the new O ring on the filter and push it down in position of the worn one.

4.    At this time, set up the new filter. If you took out one of the drain plug you have to install it again. Take off the pan and apply a coating of grease or sealant to the flange of the pan or gasket. The sealant or grease will stop up the gasket. Ordinarily, 20 inch pounds force by hand is enough to tighten each pan bolt. Never over tightened the pan bolts or even apply great force on them to avoid damaging the lip to prevent leakage. Tidy the area around the pan once the bolts are stiffened.

5.    Use a funnel to add adequate amount of fluid level into the transmission. Let the engine run for a couple of minutes to attain the engine's operating temperature. Check again the fluid level. Keep adding fluid as needed but never over fill the transmission fluid filter because this will result to a low fluid pressure that will cause premature transmission failure. Double check the transmission for spills and counter check the fluid level again after a few days.

Whichever type of filter you would want to use on your automobile whether flush filter, synthetic filter, fill filter, fluid filter, or a differential filter every time you will change your transmission fluid filter. It is always important to choose the right kind of filter that suits your car’s transmission.
