To further enhance the performance of your T-56, G-Force has come up with some additional performance options. Quicker, smoother shifting is always a plus when driving any manual transmission, and this is why G-Force has manufactured a double/triple cone conversion for your Viper, Camaro, or Cobra. While initially found only in C5 and C6 Corvette applications, this conversion allows for the installation of the superior shifting double/triple cone synchronizer setup to be installed into any T-56. If you own a Corvette, you already have this setup in your transmission. We do, however, have upgraded mainshafts made specifically for the C5-C6 transmissions. If you are looking for a transmission to be used in a project car or just want to trade in your worn out T-56, G-Force can build you a complete unit with our gear kit already installed. We can use a new or remanufactured core depending on what you would like.

Used T56 6 Speed

G-Force also has a dog ring (face tooth) version of this transmission available as well.

T56 Manual Transmission

We also have our 2.71 gear kit available in a dog-ring version. The overdrives are kept synchronized to provide a smooth, stock-like driving experience in 5th and 6th gears. Like the synchronized versions of our gear kits, the dog-ring kit is rated at 1200hp, plus or minus depending on the specific application.
