TransGo Performance Automatic Transmission Shift Kit - SK 6T70-G2

The kit includes an oversized AFL valve. The new valve is oversize which means 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. Also, a new design PR valve with longer lands restores the function and reliability of the pressure regulator system. Lastly, a new pressure relief system replaces the OE isolator valve line-up. This new system prevents expensive hard part damage due to pressure over boost.
