Solved Frozen overdrive servo cover on a 5R55S transmission.

[ACJ]

Has any body had trouble removing a servo cover on 5r55s that does not move at all I removed snap ring but cover does not move in or out, can't turn it ether
It's on a 2003 ford explorer 4x4 with 200.000 + miles with a v code on door

Welcome to this forum! Remove the bottom pan, and connect a blow gun with compressed air into the opposite side where there's a channel for fluid to go into the servo. The compressed air will push the cover out. Set the PSI to low so that it doesn't blow the cover & fluid across the room.

I tried that but did not work. I have put some liquid wrench for 3 days hoping it will loosen but it is still seized. I was told if the transmission was still on just to start up and put on drive, it would make a mess but it would blow out the cover.
Thanks for advice BrooklynBay

Spray a freeze spray on the covers (but not on the case) to cause the covers to contract.

Thanks for the update! Your thread was moved into the transmissions section, and is now marked solved in green letters. Which brand of spray did you use?

I used CRC Freeze Liquefied Gas Spray I got from Carqust
