IMPORTANT: Electrical items are covered by a 30 day EXCHANGE ONLY WARRANTY. There are no returns or refunds on such items.This NEW Shiftworks floor shifter has been tediously designed to be a direct replacement for your factory C3 shifter and properly function with whatever GM transmission you decide to use in your vehicle. The shifter body has been crafted from quality STAINLESS STEEL to fit just like the original and utilizes the original mounting bolts.
The shifter connects to the transmission with an included cable linkage. The cable mounts to the transmission with the provided pan bracket (case mounted on 6L80E, 6L90E, & 8L90E) and the correct length shift lever(s) is included as well. We even install the neutral safety / back up light switch and adjust it for you, so it's ready to simply wire into your car!
*** For REVERSE VALVE BODY transmissions, select the "Slap-Shift" option for proper operation. The Slap Shift feature has been designed to accommodate forward or reverse shift patterns of both 3 or 4-spd automatics.
*** For 6/8-Spd Automatics, know that you cannot mechanically select all individual forward gears of your transmission with the shifter. The 6L80E, 6L90E, & 8L90E's shift pattern is P_R_N_D_M. The "M" position tells the transmission to look for an electronic input (ex. steering wheel paddle shifters / buttons) on how and when to shift up or down. Putting the shifter in "D" or "Drive" will allow the transmission to operate through all gears on it's own based on what the computer tells it to do.
Our products allow our customers a viable solution to retain the factory appearance of their car without sacrificing performance. "In the olden days" many GM vehicles came with either a Powerglide or a 3-speed automatic such as a TH350 or TH400. As time went on, GM released a variety of transmissions that had overdrive capability. Overdrive simply means that the output shaft of the transmission rotates faster then the speed of the input shaft from the engine. The result was better fuel economy, as well as more gentle highway RPMs. Some of the popular transmissions in this category include the TH700-R4, TH200-4R, 4L60, and 4L80E.
The main issue arose, however, when hot-rodders and car enthusiasts began attempting to swap these transmissions into their classics the factory shifter no longer functioned properly. This is where Shiftworks comes in. From conversion kits for factory floor-shifters, to complete new shifter packages, we enable hot-rodders to upgrade their cars transmission, without moving away from a completely factory interior look. With new shifter detents, transmission components, and console indicators designed for 3-speeds, 4-speed overdrives, and even for some applications, 6 & 8-speed automatics, Shiftworks products allow you to make your transmission swap as if your car came that way.
