Vehicles with GM 4T60-E and 4T65-E transmissions may exhibit case wear at the forward band servo pin bore. The OE pin is also shorter than necessary. These issues both may lead to slipping of the forward band. The longer throw of the shorter OE pin may lead to a broken forward band. Sonnax extended length forward band servo pin kit 84571-01K is designed to address both of the issues.

Increased length optimizes forward band apply
