4L80-E Binds In Manual Low
A Bind-up in manual low can be caused by a leaking intermediate accumulator. An upgraded accumulator is available with rubber seals instead of Teflon(R) seals. The GM part number is 8680929.
Note
The accumulator was upgraded for reasons other than a bind-up in manual low. However, the upgraded accumulator is the best choice for fixing this problem.
