6T30/6T40/6T50 SHIFT KIT GMC GEN 2 (2013-2020)

The kit includes an oversized AFL valve. The new valve is oversize, therefore you will need the TransGo tool-kit part # AFL-G2-TK to ream the bore. This universal tool-kit works for all GEN2 6F35, 6T30, 6T40, 6T45, 6T50, 6T70, 6T75 and 6T80 transmissions. A new drop-in hardened steel TCC regulator valve that has re-positioned longer lands and incorporates a groove where a scarf cut seal is fitted so that it seals in the original worn bore. Lastly, a new design PR valve with longer lands restores the function and reliability of the pressure regulator system.
