This NEW re-designed Shiftworks® floor shifter has been designed to properly function with whatever automatic GM transmission you decide to use in your Corvette. The handle and knob have been designed to resemble that used in the C1 Corvettes but with the use of the pre-bent mounting tabs, the shifter body can be mounted directly to the factory floor (*call before ordering if you have a modified tunnel, the universal-style black body was our old design and may be available upon special request). Shifter can also be paired with a 1965-67 lower automatic shifter boot for a factory seal (not currently available through Shiftworks, but may be soon!).

The shifter connects to the transmission with a provided rod linkage and the proper transmission lever is also included. The linkage provided utilizes right and left hand thread so you can make your final adjustments with a simple twist of the rod. We even install a new neutral safety / back up light switch and set it up so it's ready to simply wire into your car!

About Shiftworks

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.
