Transmission Fluid

Change Transmission Fluid

When changing the fluid, always do a complete fluid exchange using equipment designed for this purpose. Most vehicle manufacturers approve this type of ATF service as an alternative to leaving 1/2 to 2/3rds of the old fluid in the torque converter if only the pan is removed to drain the transmission. ATF exchange machines are quick and easy to use, and the whole process only takes about 10 minutes. On most vehicles, the fluid is exchanged while the engine is idling with the transmission in Park. But on Mitsubishi vehicles and Chrysler and Hyundai models with Mitsubishi transmissions, oil does not flow to the ATF cooler when the transmission is in Park. You have to put it in Neutral. (Remember to set the parking brake!)
Some fluid exchange/flush machines also allow the use of a cleaner product to remove varnish and sludge from neglected transmissions. If the machine has a pressure gauge, you can use it to detect possible restrictions in the transmission fluid circuit (filter, lines or ATF cooler). Normal pressure readings may be as low as 8 to 10 psi with some vehicles. Readings less than 8 psi may indicate a restriction.
