Remanufacturing Transmissions

Remanufacturing a transmission involves completely restoring a transmission back to factory standards in a factory assembly line setting – making it as close to new as possible.

In some cases, the transmission is upgraded to include “bug fixes” and factory updates from the manufacturer such as modifications to the valve body as well as more durable parts (eg. higher quality friction material) to address common weak points of the transmission that typically caused the failure. This ensures that the transmission is as up-to-date as possible with the design and components used in brand new transmissions.

The process starts by disassembling a core (a broken/used transmission), then cleaning and inspecting all of the parts (crankshaft, camshaft and rods, head & block castings, etc.) and checking them against original equipment specifications.

All of the components that are identified as being out of specification (too worn out or damaged), are replaced with new parts or parts that have been requalified to meet very specific tolerances and standards.

The valve body is then tested and remanufactured back to original specification. Metal surfaces are measured and machined to the correct dimensional tolerances. All of the electronic components are tested, then new solenoids and other electrical parts are installed.

After machining and painting the case, the transmission is reassembled, quality checked, then hot/cold tested on a dynamometer or “dyno” prior machine prior to shipment. A dyno is a device that measures torque, power, RPMs and line pressure to make sure the transmission meets specifications and works properly.
