Tool Required VB-FIX Required
- Harsh Reverse
- High SLT pressure
- Low SLT pressure
- Overheated fluid, bushings & converter
- Poor shift quality
- TCC slip
- TCC surge
Bore wear at the spring end of the valve allows the SLT circuit and regulated converter pressure to cross leak. Bore wear at the balance end of the valve reduces converter and lube flow.
Install the Sonnax Secondary Regulator Valve & Spring kit to restore hydraulic integrity to the circuit.
Oversized Secondary Regulator Valve Kit
Also fits AW55-51SN, AF 23/33 and RE5F22A units.
- Salvages valuable core.
- Improved valve support to reduce wear.
- Improved converter feed and lube flow.
- Anodized aluminum valve replaces OE steel valve for better clearance control with the aluminum casting.
