New, used and rebuilt units
A heavy duty transmission is the most expensive part of the driveline to replace, so we give you choices. We sell new units, clean used units and units rebuilt in our Orlando shop, and we run an exchange program: you get a rebuilt transmission now and send your old one back as the core. If you would rather keep your own unit, send it in and we will rebuild it.
Transmissions we rebuild carry a one year, unlimited mileage warranty (see warranty terms; other warranties are the manufacturer's). When we rebuild, we put in the current upgrades the manufacturer has released for that model.
For every class 8 and medium duty truck
Most of what comes through the door is out of Freightliner, Kenworth, Peterbilt, International, Western Star and Mack trucks. On the heavy side that means 9, 10, 13, 15 and 18 speed Fuller and Rockwell units; on the medium duty side, the 5, 6 and 7 speed Fuller and Spicer mid-range boxes. If you are not sure what you have, the tag on the side of the case carries the model and the serial number, and that is all we need to match it.
Parts for your own rebuild
If your shop is doing the work, we supply the parts: rebuild kits, bearing kits, gasket kits, gears, shafts and synchronizers. Order online from transmission parts at pgttruckparts.com or transmission rebuild kits, or call and we will look up the part number from your model.
Worldwide shipping, and we buy cores
We ship transmissions and parts across the United States and export worldwide, with same-day shipping on stock units. We also pick up transmissions and buy transmission cores, so call before you scrap an old unit.
