Summit Racing™ Corvette-style servo piston kits allow you to swap out your OEM servo on your 700R4 or 4L60E/4L65E automatic transmission and improve shift quality and firmness. They have a larger piston area which increases band-apply pressure and holding power. These kits are drop-in upgrades and will really firm up the 1-2 shift. Includes both pistons and all necessary O-rings.

Sonnax servo release check valve kits are unique solutions. Since the GM 4L60 (700-R4) and 4L60-E Series transmissions were introduced, they have had inadequate metering of 2nd gear band servo release oil resulting in 3-4 clutch pack failure. The 3-4 clutch pack and 2nd gear band are just not properly synchronized. Sonnax servo release check valve kits combine an orifice with a ball check valve to resolve these issues and successfully extend the life of 3-4 clutches, and improve the 2-3 shift feel. Other benefits: * Provides sufficient exhaust so that 3-2 downshifts are smooth * Calibrates 3-4 clutch feed orifice without creating shift concerns

Stripped bellhousing bolts? The cause is usually the loose fit of standard Torx bits, which damage the bellhousing bolts during removal or installation of the bolts. The solution to this problem is Sonnax Torx Plus bits. Specially designed for removing 4L60E bellhousing bolts, Sonnax bits have a tighter fit with the drive head of the bolt, helping to avoid rounding out the bolt head or the bit, and prevent the bit from walking out of the bolt head. Also, these Sonnax tools permit higher torque loads to be applied, which are often needed to remove extra-tight bolts.
