TH 400 problem part name?

[4x4playhus]

I'm trying to id this part. It's from a th400 out of a 4x4 that a friend is rebuilding. He said its from his reverse manual pattern valve body area, and came across it cracked. Its like a plastic cup that holds a spring over the piston in the valve body. Does anybody know the name? Part #?



Thanks,

Scott

Your dealer should have it or a transmission parts place or transmission repair shop.
If you re reffering to the piston in the valve body.
Ask for a front accumulator piston some are aluminum.
