After changing the transmission fluid and filter it will shift into gear but the car will not Move

Hi,

When you refilled the transmission, how much fluid did you put in it? Also, was the filter a bolt on filter? If so, was it properly installed?

If it worked before, either the fluid is low, the filter isn't properly installed, or you missed a seal/o-ring. Take a look at the attached pic. Is the transmission fluid in that range when the engine is warm and running in park?

Let me know.

Take care and God Bless,

Joe

The most common cause of this is due to the fluid being low. When you shift the transmission into gear the manual valve routes the fluid to the specific clutches so that it apples that gear. So this requires two things. First the proper amount of fluid so that when it sends it to the clutches it doesn't pull in air. Second, it needs to be pressurized which means the pump needs to be operating and there are no cuts in any of the seals allowing the pressure to escape.

When you filled the fluid did you warm the engine and then run it through all the gears about 5 times so that it sends fluid through the transmission and then you can top it off? If not then you filled the pan and once you put it in gear it pulled the fluid into the unit and left the pan empty which means the pick up pulled in air.

Below is the process from the manual. Let me know what happens.
