Putting a 904 Valve Body into a 727: Mopar A727 Rebuild #9 

Beat up hole is the relief checkball hole. The TF2 kit from TransGo comes with revised springs for the different types, color coded. I file/sand the surface flat again and then use the checkball itself and a hammer to reshape the hole to seal again.

I can get you as many separator plates as you need.

Hi. I've heard the 904 and 727 push button valve bodies and plates are exact the same. Do you know if that's true?

Sonnax Valve Body Separator Plate Part No. 22747-86

looks almost the same as a 42RE-se 4th gen which is A500 I think separator plate says 73

How did the tranny work for ya after installation ? Good, I hope. Cheers

Are the three unused threaded holes for mounting the filter?

I opened mine up and the spring and ball bearing weren’t in there…

Was the 904 and the 727 both lock up converter style trans
