4r44e reverse servo part question

[brownz]

The reverse servo piston is stuck any ideas how to remove to replace o rings. I have been having a problem with reverse after installing new valve body and went to change orings and cover is removed but cannot get the servo out . I dont want damage anything so if anybody have a similar situation please let me know?

Please see last post of this thread

I got it out by wiggling it back and forth while pulling it outward. There was bunch a dirty fluid behind it. Now the weird part was there suppose to be a spring because there was not.I am quite sure it didn't pop out because i was holding onto the piston.Is that right that there is no spring all replacements I saw had a spring.

reverse servo parts needed

while removing reverse servo on my sons ranger there was no gasket under the plate and there was no spring either. I did notice the shaft is spring loaded. What parts do I need for the 4r44e reverse servo? I understand the d-rings are better do i need a spring and the gasket that is in the picture as well? the bore has no gouges and the piston is smooth so I do not believe I need a sleeve. Lastly is there a supplier that you recommend for quick delivery or will overnight? I have to get this truck out of garage . Thanks

The spring was used in the A4LD, but not on your model. Here is a link for the TransTec D ring kit: http://www.transmissionpartsusa.com...isse_reverse_servo_D_ring_p/230-00023256k.htm. This link has the gasket for the servo cover: http://www.transmissionpartsusa.com...everse_servo_cover_gasket_p/230-000023128.htm
