Shift Correction Package

The Superior Transmission Parts K4L60-E is a Shift Correction Package engineered for GM's 4L60E automatic transmission, covering model years 1993 through 1997. This comprehensive kit addresses a variety of common transmission issues, offering both regular and heavy-duty application benefits in a single package. This kit is specifically designed to tackle problems such as bind-up in reverse, low and reverse clutch burn-up, delayed engagement in forward and reverse, and the common "slide in 2nd" condition. It also helps resolve 3-4 clutch burn-up, insufficient lube oil, and general clutch and band failure. Furthermore, the K4L60-E kit is instrumental in preventing Code P1870, which is often associated with converter burn-up. Beyond addressing these specific issues, the Superior K4L60-E Shift Correction Package works to prevent premature wear of the forward sprag. A key feature is its conversion of the lock-up system to an on/off function, which effectively helps to stop TCC slippage codes, leading to a more reliable and smoother driving experience.
