Extreme Duty Street / Strip - + $500.00 Core Charge

In order to raise performance above the Level Two units, the input shaft/drum and sun shell assembly
strength must be addressed. Anyone who has built serious Th-2004R Transmissions has, at some time experienced failure of one or more of these components. Our Level Two Transmissions parts have proven to be reliable to the torque levels described in Level Two and our return rate demonstrates this. We experience less than 1% failure on our Level Two units.

Once you get into these engine torque and horsepower levels above the Level Two Transmissions, the input shaft to drum connection point becomes prone to fracture and the spline section will start ripping off the sun shell. Our Level Three Transmissions have the following parts added for increased strength and reliability above 450 hp and 450 ft/lbs. of torque. These components are specifically engineered to help prevent breakage in applications with exceptionally stout motors. Details of these parts can be seen at
While the late model factory sun shells are definitely a big improvement, they are certainly not up to the hard core use that our sun shells are built for. Our Level Three Transmission includes the following upgrades from Level Two: Heavy duty input shaft/drum assembly, the reinforced sun shell package and fourth gear servo. These parts will live at horsepower and torque levels over 60% greater than the stock components are able to tolerate!

Our Level Three units have everything included in Level One and Level Two plus the Extreme-Duty package!

Kolene steels and Red Eagle frictions.
Racing level band.
Custom machined input shaft using 300M aerospace alloy available for additional charge
Modified line bias system.
Extra modifications to spacer plate for aggressive performance.
Custom machined anodized red billet servo for greater clamping performance.
Main boost valve is upgraded to a .500" main boost valve and our oversized low/reverse boost valve produce higher operating pressures for firmer, quicker shifts and better clamping pressures in all gears.
