GEN3 6T30 - 6T40 - 6T45 Transmission
TransGo 6T40-G3 SHIFT KIT® Valve Body Repair Kit

REAMER TOOLS REQUIRED

This TransGo 6T40-G3 SHIFT KIT® Valve Body Repair Kit fits General Motors vehicles equipped with GEN3 Series 6T31, 6T41, 6T46 and 6T51 automatic transmissions. This kit properly addresses the most common low mileage failure on these units with three drop-in valves and two oversize valves, both of which require a tool
Actuator feed limit valve requires # AFL-G2-TK
Lube boost valve requires # 6T40G3-LB-TKC

At the start of production for the 2015 model year, the 6T40 series of transmissions upgraded to GEN3 with an off-axis chain driven pump incorporating a lube boost valve.

This lube boost valve is very active and exhibits extreme low mileage wear (up to .060”). To salvage the pump, TransGo engineered an oversize hardened steel valve and spring combination to minimize the valve oscillation responsible for premature bore wear, ensuring a lasting fix.

Installation of the new design lube boost valve assembly requires a one-time purchase of carbide tool kit #6T40G3-LB-TKC. The two included guides cover all 6T40 GEN3 series pumps and the dual-piloted carbide reamer ensures quick, easy and precise machining that will last infinitely longer than high speed steel.

Corrects/Prevents/Reduces:
  • Ratio or solenoid performance codes
  • Erratic TCC apply or TCC hunting
  • Overheating
Includes:
  • Drop-in GEN3 pressure regulator valve and spring
  • Drop-in GEN3 shuttle valve and bushing
  • Drop in TCC regulator valve and spring
