There are several versions of the 700R4 transmission, including heavy-duty, super-duty, and Xtreme SS models. In 1993, the transmission’s hydraulic shifting system was replaced with electronic controls for the 4L60E version. In 1990, General Motors changed the name of the 700R4 to 4L60, which represented 4-speed, longitudinal, 6,000-pound gross vehicle weight rating. Overheating can also cause a warped valve body, which can be problematic when changing gears. Slipping between 3rd-and 4th gears can occur when overheating weakens the metal of the clutch-pack disks, causing a problem with the clutch-pack that engages those gears. Overheating is another common issue, though it can be avoided by installing an auxiliary transmission cooler. Transmission Swap Includes B&M Holeshot 2400 Converter New. The transmission has several common problems, including a broken 27-spline input shaft in early versions of the 700R4 (after 1987, 30-spline shafts were developed to improve the reliability of the gearbox). 93 4l60e to 700r4 swap over drive-a 90 would be-non computer right.

700r4 transmission conversion no electronics upgrade#
It also became a popular upgrade for older rear-wheel-drive General Motors vehicles. I abated the 15 core fee by returning a C-4 transmission I had from my Turbo Pinto swap. The 700R4 was GM's overdrive four-speed replacement for the three-speed Turbo350. The transmission was designed for trucks and large cars but is compatible with a variety of Chevrolet, GMC, Cadillac, Pontiac, Buick, and Holden vehicles between 19. It is a four-speed automatic transmission with overdrive and was introduced as a way to make V8-powered cars and trucks more efficient. To the best of my knowledge, this is the first 700r4 conversion in a Mk10 to be successfully done. The General Motors 700R4 transmission was manufactured by Chevrolet in 1981 to run with 1982 model year vehicles. Not all the restoration work on the Mk10k, which is ongoing, but the drive-train rebuild including the conversion to GM 700r4.
