Description

The factory AOD automatic in your '79-'93 Fox-body Mustang was never designed for serious performance - soft shifts, reliability concerns, and limited torque capacity leave power on the table. This complete conversion package replaces that 4-speed automatic with the TREMEC T56 Magnum, the kingpin of TREMEC's high-performance lineup. Based heavily on the TR-6060 found in modern factory muscle cars like the Dodge Challenger, Viper, and Chevrolet Camaro, the Magnum combines OEM engineering with the most popular features from the proven TKO 5-speed platform.

The Magnum delivers unbelievably crisp shifts thanks to spring-loaded ball-type inserts that reduce friction and prevent notchy engagement. Unlike the original T56's cast-aluminum forks with removable steel links that wore into the aluminum over time, the Magnum's redesigned shift forks have the shift link permanently mounted for precision shifting and zero deflection. All speed gears feature substantially increased face widths with laser-beam welded engagement teeth, enabling precise tooth angles and positive stops to prevent over-travel on hard shifts.

Where the original T56 used a torque-limiting two-piece countershaft, the Magnum employs a much stronger one-piece shaft with thicker journals and widened gear faces - a design first proven in the Dodge Viper. The 3.66-quart fluid capacity accepts TREMEC HP-MTF, Dexron III ATF, or GM Synchromesh. Split ring retainers replace traditional snap rings for greater thrust load capacity and tighter tolerances throughout.

This guided package system walks you through selecting every component for your specific build - from transmission and bellhousing to flywheel, clutch, hydraulic release system, shifter components, crossmember, and driveshaft. Compatible with Ford Small Block V8 engines in 1979-1993 Mustangs. The conversion requires little to no tunnel modifications, and the shifter position is retained for that factory appearance.
