Product Description
4T65E 4T60E Extended Length Forward Band Servo Pin Kit
Sonnax Part Number: 84571-01K
NO TOOLING REQUIRED
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
- PTFE seals on both sealing diameters
PACKAGE CONTAINS
- Servo Pin
- Pin Seals (4) PTFE, 2 Extra
SYMPTOMS
- Band failure
- Forward slip
- Burnt Forward band
CAUSE
The OE forward band servo pin was designed with excess travel needed to apply the band. This travel can affect band apply, and the energy from pin travel can cause the band to break over time.
CORRECTION
Replace the OE forward servo band pin with Sonnax extended length forward servo band pin kit to position the pin closer to the band apply position.
