Hey guys my tranny is slipping a little in the 2-3 shift.... full throttle is when it slips most. The tranny is not low on fluid and the TV cable is adjusted properly.\\

I installed a B&M shift improver a few weeks ago and the 1-2 Accumulator housing spring was broken so the little chunk of spring was floating around in the housing scratching the side wahhs where the piston has to seal. Woul dthis be causing my slipping 2-3? 1-2 is great and firm though. I used type F tranny fluid too....

Tranny shifts to OD at full throttle too

But I am going to buy a new accumulator housing and 1-2 piston O-ring. Also one of those GM fluod pressure regs so she doesnt whine and grind at low rpm so much its really annoying.

 

No one?
