TransGo SK 700 Shift Kit for GM 700R4 / 4L60 (1982-1993)

The 700R4 (and its early 4L60 sibling) is a strong transmission with one fatal habit: it lives and dies by the throttle valve. Get the TV cable adjustment slightly wrong and there is no line pressure rise under load, the 3-4 clutch and the 2-4 band slip on every shift, and the unit cooks itself in a few thousand miles. Half the burned 700R4s on the bench got there because of a cable that was a quarter inch off, not because anything actually failed. This is the kit you install while the valve body is apart so a rebuild does not walk right back into the same problem.

The heart of it is TransGo's Bootstrap TV system, which reworks how the throttle valve feeds line pressure so pressure comes up with load the way it should instead of hanging on a perfect cable setting. The result is a firm, clean 1-2, 2-3, and 3-4 with the band and 3-4 clutch applying hard enough to hold instead of dragging through the shift, which is what actually burns them. It also cleans up the early or late shift complaints and the soft part-throttle changes these units are known for. You get the valves, spacers, springs, bushings, check balls, seals, and gaskets, plus TransGo's step-by-step instructions.

It fits the GM 700R4 and 4L60 from roughly 1982 through 1993 -- the transmission behind small blocks in Silverados, C/K trucks, Blazers, Suburbans, Camaros, Corvettes, and the rest of the rear-drive GM lineup of that era. Whether you are rebuilding a high-mile core, chasing a slipping-band or burned-3-4 complaint, or building a truck that tows, this kit fixes the design flaw for good. Part number TGOSK700. Ships from the USA.
