1. Here's the Fast-Gate shifter from TCI Automotive. In the box you will find the shifter assembly, a black cover, a bunch of brackets and levers, two micro switches, and a 5-foot shift cable. TCI offers optional shifter cables in 2, 3, 4, 8, 10, 12, and 14-foot lengths. It’s a universal design so it works with just about every GM three- and four-speed automatic transmission, even the late-model 4Ls.
