Rockwell transmissions

Quality Rockwell and Meritor truck transmissions for sale, rebuilt or by exchange, and the parts to repair them.

We sell Rockwell truck transmissions and OEM parts, rebuild kits and service for every Rockwell model. That includes the Meritor G platform transmissions, which we keep in stock and ship worldwide.

Which trucks

Rockwell Meritor transmissions went into Freightliner, Kenworth, Peterbilt, International and Western Star trucks. If you have one of those with a Rockwell or Meritor tag on the transmission, read us the model and serial number and we will match the unit or the part.

Before you replace it

A transmission that will not shift right is not always a bad transmission. Most manual transmission problems can be diagnosed in the truck, and often the cause is external: the shift tower, the linkage, the clutch brake or the clutch itself. Checking those first can save you the cost of a unit you did not need.

Rebuilt and exchange Rockwell transmissions

When the transmission does need work, we rebuild your existing Rockwell, or supply a rebuilt unit through our exchange program so the truck is down for as little time as possible. Transmissions we rebuild carry a one year, unlimited mileage warranty (see warranty terms; other warranties are the manufacturer's). We build in the current Rockwell Meritor upgrades for your model when we rebuild.
