G-Force T-5 Synchronized Transmission With 26 Spline Input Shaft For 1987-1993 Ford Mustangs.Dedicated racers have associated the G-Force marquee with superior products for years, and now they bring that reputation to the street enthusiast as well.
These transmissions allow for substantially increased horsepower handling capabilities while utilizing the factory T-5 location and mounting dimensions. This simplifies installation tremendously and assures the stock look, if so desired. For vehicles not already running a T-5, an installation kit may be available for your specific application. While the G-Force Street 5-Speed transmission may look identical on the outside to a stock T-5, rest assured that they are vastly different on the inside.
This transmission features synchronized, high nickel gears and a heavy duty 26 spline input shaft. The synchronized transmission features helical-cut gears for better noise reduction while still retaining extra gear width.
Every transmission even comes with the required oil. This oil must be run with the transmission to insure optimum performance and durability. Also, the shifter installation on these transmissions is identical to a stock T-5, so any existing stock or aftermarket shifter can be installed. We recommend the use of the Pro-5.0 aftermarket shifter.
Normally, the stock T-5 is rated at about 300 ft-lb of torque capacity. While this is fine for stock or lightly modified engine combinations, especially running small street tires, it isn't generally enough for most of today's high powered street/strip engine combinations. Especially those running bigger, more aggressive tires. This is where the G-Force Street 5-Speed transmission comes into play. Although G-Force does not like to put torque or horsepower ratings on their products due to the vast differences in clutch, engine, chassis, tire and mounting combinations, they can give a very rough estimate. There are simply too many variables to consider when trying to figure out how much power or torque a transmission will take in a particular application. Generally, it can be assumed that with the available upgraded mainshaft, the G-Force Street 5-Speed kit will handle roughly 600 hp or 500 ft-lb. of torque in a 3300 lb. vehicle running drag radials at the track with a moderate clutch upgrade. Obviously this is just a rough estimate regarding the power and torque handling capability, but it should give some idea as to what the G-Force Street 5-Speed transmission will handle in your particular application.
G-Force's Street 5-Speed transmissions are currently available with the preferred 2.94, 1.94, 1.34, 1.00 ratios in gears 1 thru 4. Because most performance enthusiasts run a relatively steep rear gear, the synchronized transmission utilizes a stock .59 overdrive which allows the engine to turn less RPM at cruising speed. This equates to less engine wear and better gas mileage while still maintaining incredible acceleration in the first 4 gears - amazing!
