HERE'S HOW WE MAKE THE 1000/M74 BETTER:

Pump Improvements

Our completely remanufactured late-design pump features new line bore bushings to stop leaks, and late-OEM front pump covers to eliminate the cracking around the torque converter pads prevalent in the Allison 1000.

Torque Converter Overhaul

We update the relief spring for a torque converter that exceeds OE requirements, eliminates delayed engagement, and lowers operating temps.

Valve Body Corrections

The upgraded lube regulator valve keeps operating temps low, and an updated E-Shift valve spring and F-Trim valve sleeve improve shift quality and increase durability.

Precision Bushings Upgrade

We upgrade to all-new custom-spec bushings and polish machined surfaces to a mirror-like finish of 15 RA or less. Our Tru-Flat qualification ensures the case, valve body, pump, and channel plate are free from the cross leaks and pressure losses common to the Allison 1000.

Increased Load Capacity

We upgrade the C3 clutch assembly by adding an extra friction plate - increasing the load capacity to handle heavy-duty towing applications.

HERE'S WHY OUR TRANSMISSIONS LEAD THE INDUSTRY

Every transmission we touch gets the same treatment:

Teardown and Triple Clean – Every transmission is disassembled, inspected, and cleaned three times. We also chase all threads and install all new bushings during this process.

Valve Body Rebuild and Test – Our most experienced team members rebuild and inspect each valve body before testing it using our C.A.R.S. testing system, which simulates real-world use and validates the valve body.

New O-Rings, Gaskets, and Seals – Once the valve body is tested, the transmission is reassembled with all new o-rings, gaskets, and seals.

Dyno Testing – Our custom dyno testing machines spin and load test every transmission to verify it’s ready for the road.
