Automatic Transmission Valve Body Repair Kit

The TransGo SK 45RFE-A SHIFT KIT® Valve Body Repair Kit is engineered to resolve common issues found in 45RFE, 545RFE, 65RFE, 66RFE, and 68RFE transmissions. These problems often include rough lock-up apply, lock-up slide bump apply, TCC slip codes, excessive transmission cooler pressure, and converter drain-back. A frequent cause of these symptoms is a worn TC limit valve bore in the pump, which can lead to the belief that the entire pump needs replacement. This kit provides new, innovative drop-in TC limit parts that effectively restore the TC limit system's function, regardless of the pump bore's condition, thereby avoiding the expense of a new pump. Key features and benefits of the SK 45RFE-A kit include a new drop-in torque converter limit valve system for both early and late pump designs, recalibration of the TCC accumulator system for optimal converter clutch apply, and a heavy-duty snap ring for the underdrive/overdrive pressure plate to prevent snap ring blow-out. The kit is designed to correct or prevent rough lock-up, TCC slide bang, TCC slip codes, low line pressure code P0868, drain-back, and limp-in mode operation.
