![]() ![]() The Sonnax super hold servo can be used as an upgrade from a stock "Corvette" servo or to add max holding power in extreme applications.Ĭompared to the "Corvette" servo, the 4L70-E servo is a modest increase in size over the V6/V8, 8642553 casting servo, and it will not change the shift feel as dramatically the Sonnax "Corvette" servo or a larger Sonnax 2nd Gear super hold servo would. The exclusive Sonnax design features Viton ® D-rings for more consistent apply and release than stock servos. The Sonnax 2nd Gear "Corvette" ratio servo kit 77701-04K is an upgrade from the smaller-ratio stock servo and adds holding power in many street applications. This mid-range servo size is a perfect first option to consider when upgrading stock-type applications. However, if you are looking to add "a little extra" to a heavy-duty rebuild and want a little more 2nd band apply area, but the Corvette or larger aftermarket servo is just too much for a daily driver, try Sonnax 4L70-E servo 77701-02K. The 8642553 casting used in V6 and V8 applications is by far the most common size we see. ![]() With the 2007 4L70-E, there is a fourth OE servo size that gives builders another choice when looking for something with increased performance. All of these servos have a “proper” apply to release ratio and accommodate a cushion spring. For years we have known the 4L60 and 4L60-E 2nd Gear servo came in three different sizes, and one aftermarket size in the Sonnax 2nd Gear super hold servo kit 77911-03K. ![]()
