TransGo Performance Automatic Transmission Shift Kit - SK A4CF

This TransGo SHIFT KIT® Valve Body Repair Kit includes an oversized USA-made steel reducing valve to completely restore the hydraulic circuit integrity. In order to install this valve, the bore must first be reamed oversized. If you don’t already have the reamer and guides, you will also need TransGo part # A4A6-RV-TK. On the other hand, the new drop-in torque converter regulator valve system does not require any tooling. The furnished bushing, valve, spring and end plug, will restore the torque converter regulator function using existing worn bore.
