With thousands of T5 and T56 kits already sold, G-Force has come up with another exceptionally durable gear kit. This new gear kit is for the TR3650 5-speed transmission that comes standard in the 2001 to 2010 V8 Mustangs, although this transmission will fit almost any application with the correct bell housing.

This 1000 horsepower capable gear kit is the first aftermarket gear kit offered for this transmission and we’ve taken the unprecedented step of offering this kit with precision ground gears to help eliminate some of the NVH (Noise, Vibration, and Harshness) associated with aftermarket gear designs. The gear design is from our proven T56 combination so there is already a vast database of testing experience with this particular design. Gear ratios for this kit are 2.90 1st gear, 1.91 2nd gear, and 1.37 3rd gear. 4th gear is still direct drive (1.000) of course and a .58 overdrive gear accommodates the typically steeper rear gear that most cars run for street/strip applications. There is also a .69 overdrive option available.

Great for launches and even better that stock fuel mileage in most applications. Also, this kit utilizes the factory 1st gear on the mainshaft for greater cost savings as compared to manufacturing a new gear. We’ve found that the large stock mainshaft 1st gear is more than adequate for virtually any application.

This kit also utilizes the factory mainshaft as they already have a large 31 spline output that will hold up to even the most severe punishment. This helps keep costs down and allows us to offer the kit at a more attractive price than would be possible otherwise, while increasing the level of overall quality for less cost.
