All Over the Map: Attacking 4L60/E Burnt 3-4 Clutches with Confidence
Sonnax Sure Cure kit SC-4L60E is a comprehensive reconditioning package for GM 4L60-E, 4L65-E and 4L70-E PWM units featuring the best Sonnax products developed to help rebuilders restore and enhance transmission performance. Sure Cure components are the same Sonnax parts sold individually to resolve common valve body complaints as well as other transmission problems. The high-quality Sonnax parts in each Sure Cure kit repair worn areas and protect the transmission against future damage. Plus, each kit comes with easy-to-read, step-by-step installation guide that covers the inspection and repair of the most critical areas of the valve body.
The '95-later 4L60-E, 4L65-E and 4L70-E units with PWM/EC3 (electronically controlled capacity clutch) control can be identified by the 13-pin case connector, PWM/TCC solenoid and PWM pump (five solenoids). All components in this kit are compatible with '93-'94 non-PWM units EXCEPT the TCC apply valve 77805E-K installed in the pump. These units can be identified by the 12-pin case connector, only having a 3-2 solenoid in valve body (four solenoids).
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
