GM 4L60E/4L65E/4L70E 3-2 Control Valve Spring
Sonnax Part No. 77754-23
The 3-2 control valve spring in late-model 4L60-E and 4L65-E valve bodies often breaks, and can cause a 3-2 bind and/or 2-4 band to overheat. This spring is often found to be broken during valve body service, and OE replacements are not available. Sonnax offers a replacement spring 77754-23 for 96-later 4L60-E and 4L65-E units.
- Inexpensive replacement for unavailable OE spring.
- Salvages valve body core.
NOTE:
This spring works only in '96-later on/off- style 3-2 control valve bodies. It will not work in 1993-95 PWM-style 3-2 control valve bodies.
