Transgo 6T70 Shift Kit – Generation 2 ONLY (13-Up)

 SK 6T70-G2

Fits 6T70, 6T75, 6T80 GEN2 2013-on
without pressure switches
Requires AFL-G2-TK toolkit


This 6T70-G2 Shift Kit fits 2013 and newer General Motors vehicles equipped with a GEN2 6T70, 6T75 and 6T80 automatic transmission. Common complaints with this transmission are erratic shifts, broken parts, TCC slip as well as various solenoid performance and gear ratio codes. This kit does not fit GEN1 units.

One source of the shift complaints is the wear at the actuator feed limit (AFL) valve bore. The purpose of the AFL valve is to limit the pressure going to the solenoids. The AFL valve spring is calibrated to prevent the solenoid feed pressure from exceeding a predetermined PSI, no matter what main line pressure is. This is necessary to prevent more fluid from being fed to the solenoids than they can effectively regulate and limit what max line pressure output is. If the pressure feeding the solenoids is too high or too low, their output will also be too high or too low. As a result, shift quality complaints and codes can occur along with low or high main line pressure.

The other source of the shift related complaints is wear at the pressure regulator valve and or bore. When the valve or bore wear occurs, EPC boost signal oil is going to be low. The end result is lazy or slow pressure boost response and the related symptoms similar to the worn AFL system.

The TCC slip problems can occur in this transmission from wear at the TCC regulator valve bore. This kit addresses the wear with a redesigned valve that incorporates a scarf cut sealing ring and extended land that restores the integrity of the valve bore. Lastly, a new relief system prevents expensive hard part damage due to accidental pressure spikes.
