Compatibility - Fits GM 700R4, 4L60, 4L60E, and 4L65E transmissions from 1982 to 2014. This servo is a direct drop-in replacement for the listed models and years. Installation - No assembly required. Remove the old servo and install this servo as a straightforward replacement. Performance and benefits - Increased holding power for high performance applications. Provides firmer shifts and improved control under higher torque conditions. - Firm up shift response, contributing to more determined transmission operation. - Can help prolong transmission life when installed early by reducing slip and excessive wear during shifting. Construction and fit - Engineered as a direct replacement for the specified GM transmissions, ensuring proper fit and operation without modification. Use scenarios - Street performance with upgraded torque: users upgrading engines or gearing can benefit from firmer shifts and improved holding to manage increased torque. - Towing or heavy loads: enhanced holding power helps maintain shift integrity and transmission control under load. - Track days or competitive driving: more consistent shift feel and response for repeatable performance.
