Understanding T56 Swap Kit Components
Types of T56 Transmissions
First, it is essential to understand the different types of T56 transmissions available. Various versions of the T56 exist, stemming primarily from their applications in other vehicles:
LS1/LT1 T56
Commonly found in GM vehicles like the Camaro and Firebird, these are frequently chosen for their affordability and ease of availability. They typically feature a slightly different bellhousing bolt pattern than the original Mustang engine.
Viper T56
These transmissions are found in the Dodge Viper, and can handle a lot of horsepower. They offer improved strength and can be a more suitable option for extreme performance builds. However, this can come with a higher price tag.
Aftermarket T56
Some companies build brand new T56 transmissions, offering a range of options, gear ratios, and features. They are often designed specifically to fit certain applications, including the Fox Body.
Before selecting a T56, you must consider how it will integrate with the engine in your Fox Body. The bellhousing type, and its mounting pattern, will dictate compatibility. Researching the availability of aftermarket bellhousings is very important.
Now, let’s break down the essential components of a T56 swap kit:
Transmission Crossmember
This is a critical piece that mounts the transmission to the car’s chassis. A specific crossmember is designed to properly position the T56.
Transmission Mount
The transmission mount bolts the T56 to the crossmember, providing support and absorbing vibrations.
Bellhousing
The bellhousing connects the transmission to the engine. You’ll need one specifically designed to match your engine and the T56 transmission you’ve chosen. This is one of the most crucial parts of the swap process.
Clutch and Flywheel
A high-performance clutch and flywheel are essential. They need to match the torque capacity of your engine and transmission, and should be selected to fit the T56.
Pilot Bearing/Bushings
This component supports the input shaft of the transmission within the engine’s crankshaft.
Clutch Hydraulic System
The T56 uses a hydraulic clutch system (unlike the cable clutch found on most Fox Bodies), so you’ll need a master cylinder, slave cylinder, and the necessary lines to connect them.
Driveshaft Modifications
The T56 is typically longer than the T5, so you may need to shorten or modify your existing driveshaft, or opt for a new one designed for the swap.
Shifter and Shifter Mounting Plate
The T56’s shifter position may differ from the original T5. A shifter and mounting plate are needed for correct placement.
Wiring and Sensors
You’ll need to ensure the reverse lights and speedometer function correctly, which may require wiring modifications or adapters.
Clutch Kit, Fork, and Throwout Bearing
These essential clutch components must be designed to work with your new T56 transmission.
Optional Components and Considerations
Some optional components can improve the experience even further:
Upgraded Clutch
If your engine is modified for more power, a more robust clutch is recommended.
