- Accumulator pin kit 4T65E
- Pins (10)
Inconsistent shifts, high shift adapt numbers and burned clutches in a 4T65-E can all be traced back to worn accumulator pistons. Pin bore wear allows clutch apply pressure to exhaust into accumulator circuits and decrease clutch apply pressure.
High shift adapt numbers
Inconsistent shift quality
Worn 1-2 and 2-3 accumulator piston pin bore
This oversized replacement accumulator pin restores the proper fit between the piston and the bore and allows re-use of the original aluminum piston.
