I'm in the process of doing a shift kit install with all the goodies. I got the pinless accumulator pistons for the forward and 1-2 accumulator pistons and they fit really tight. Are they supposed to be that close or should they slide right in?

This is the first time I've done anything to a transmission so I want to get everything right the first time.

 

Did you put vasoline on the rubber oring before you put it in? I dont remember how mine was, but I remember hating every second installing that shift kit and goodies.... Next time I will just pay a professional... Not to mention getting soaked in tranny fluid... But it was worth it in the end...

 

Yeah I lubed the orings before I put them on the pistons. I also lubed the bores with ATF and they just seem a lot tighter than factory.

I didn't get soaked with fluid since its sitting the floor in my garage

 

coat them with atf, the pinless pistons have two oring seals, and they must fit very tight to keep them from getting cocked in the bore.

 

x2, what part numbers do you have? My fwd and 1-2 accumulator pistons fit fine with alittle bit of ATF on the new orings.

 

I don't remember the part numbers but they're made by Sonnax. I pulled them and coated them again and they fit fine; its just that the stock pistons came out a lot easier.
