Hi ,
I need a GM part number for the pin that the foward clutch accumaltor piston rides on inside the valve body, can anyone help finding the part number? the dealer has no clue as to what im talking about and only wants to sell me an entire valve body that i do not need. I found the one for the 4th accumaltor part# 8628273 that goes in the tranny case but it is bigger in diameter. I know the pin for the foward accumaltor is available from GM i just need the part number, can anyone help?
thanks

 

Go pinless!

 

i saw those.... but i didn't want to do that just yet...

 

anyone?

 

There is a reason why they aren't listed on any of the performance 700R4/4L60/4L60E websites. For under $10, you can be done with the potential leak path all together.

If you insist, the dealership probably has this part for $5 or so. Just guessing. Do you already have a new piston? If not, it really is a no-brainer, IMHO.
