Sonnax 77754-23 3-2 Control Valve Spring for 4L60E 4L65E 4L70E Transmissions

The Sonnax 77754-23 3-2 control valve spring is designed to salvage the valve body and prevent 3-2 bind and/or 2-4 band overheat in GM 4L60E, 4L65E, and 4L70E automatic transmissions. The 3-2 control valve spring in late-model GM 4L60-E, 4L65-E and 4L70-E valve bodies often breaks, and can cause a 3-2 bind and/or 2-4 band to overheat.

• Designed for 1996-later 4L60-E and 4L65-E units
• Works only in '96-later On/Off style 3-2 control valve bodies
• Constructed from steel for durability
• Inexpensive replacement for unavailable OE spring

This Sonnax valve body spring restores proper hydraulic control in the transmission valve body, ensuring reliable shifting performance and protecting critical transmission components from premature wear.
