Changing Transmission Fluid – Removal Of Filter

Removing the filter is an effective method, whether you are changing manual transmission fluid or changing automatic transmission fluid. The process does not differ much between these two types of car.


  • First of all, you will want to jack-up your car and remove the oil pan. Under the oil pan is the filter.

  • Remove the screws of the filter until you can completely pull it loose of the vehicle.

  • As you pull it free, ensure that you do not damage the sealant that holds the gasket in place.


  • Then give the filter a thorough wash, making sure to remove any metal impurities that have been collected at the very bottom.

  • Once thoroughly cleaned and emptied of fluid, replace the filter and then refill with fluid.

You will need to check your vehicle’s manual for exactly how much fluid to put in, but the important thing is to not fill it up too high or too low.

Cost Of Changing Transmission Fluid

The cost of changing transmission fluid depends on a number of different factors. This is true whether you do it yourself or if you hire a professional to do it for you.

The model of your car, and thus the type of fluid that it requires, is the primary factor that will determine the overall cost of changing transmission fluid. The value of your car, in terms of how long you have had it, is taken into account as well.

Who is carrying out the work is obviously a key factor. If you do it yourself then you save on the costs of labor, but you will also need to purchase the replacement fluid itself. But it is not an overly expensive task, whether you are changing transmission fluid yourself or hiring a professional to do it for you.
