727 Installed - No Movement in Gears

I'm glad you were able to find the problem.
I recently rebuilt my transmission and it also was too brutal for me on the 1-2 & 2-3
Shift.
I had put in a billet accumulator with built in blocker rod, A& A transmission told me to replace it with a stock aluminum one with the big spring and no blocker rod to tone down the 1-2 shift.
I did and it's perfect now!
But the 2-3 shift is still harder then I like.
They said to change the flat snap ring I put in the front drum to a wavy one.
I didn't want to pull it back out for that just yet.

Hope that helps.
