****See below now offered with New torque converter options ****

Remanufactured converter is our stock build

New Luk Double Disc converter ( this is what the OEMS are using and eliminates the typical 6L shudder)

Heavy Duty Billet cover converter( for the heavier use applications eliminates shudder while proving unrivaled heavy duty performance)

This transmission MUST be reflashed before it is put into service and all transmission oil coolers must be replaced

We also supply this with a Thermostatic bypass to eliminate the high failure point of the OEM transmission lines. This must be installed and typically is what caused the initial transmission to fail***

Every remanufactured transmission we sell is backed by a Million Mile warranty up to 7 years, the best in the industry. The reason we can offer this warranty? Every transmission undergoes the same rigorous remanufacturing process:

1. 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.
2. 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.
3. New O-Rings, Gaskets, and Seals – Once the valve body is tested, the transmission is reassembled with all new o-rings, gaskets, and seals.
4. Dyno Testing – Our custom dyno testing machines spin and load test every transmission to verify it’s ready for the road.

When you buy a remanufactured transmission from Powertrain Products, you’re buying a transmission that meets or exceeds OEM specifications. And we back that claim up with our available 7 Year, 1 Million Mile Warranty.
