Check the outside of the transmission first
Even the best transmissions have to be maintained, repaired or replaced. Most manual Fuller problems can be diagnosed with the transmission still in the truck, and in most cases the trouble is outside the case: a worn shift tower, linkage that needs rebuilding, or a clutch brake or clutch that needs replacing will all make a good transmission shift badly. Have it looked at by someone who knows Fullers before you pull it. Call us and we will talk it through with you.
Rebuilt Fuller transmissions
When the transmission itself is the problem, we offer rebuilt Fullers at discount prices, as an outright sale or as an exchange against your core. Transmissions we rebuild carry a one year, unlimited mileage warranty (see warranty terms; other warranties are the manufacturer's).
Fuller transmission parts
For the shop or truck stop doing its own repair, we stock gears, bearing kits, input shafts and gasket kits for Fuller transmissions: genuine Eaton parts, and quality aftermarket replacements made to fit Fuller transmissions where they make sense. One call does it: we will help you identify the part from the model and serial number, or ship you a replacement unit to get the truck back on the road.
