Mack Transmission Parts

New, used and rebuilt Mack transmission parts shipped to your shop or job site, from a single seal to everything a rebuild needs.

We stock parts for Mack transmissions in heavy, medium and light duty applications, including manual shift units, for anything from off-road work to over-the-road hauling. New, rebuilt and used parts are available, and stock parts ship the same day.

Parts a Mack rebuild calls for

• Rebuild kits and bearing kits
• Gears and shafts
• Shift forks
• Bearings, seals and gaskets
• Cases and top covers

If your rebuild needs ten items, make one call. We stock the gearing, cases, seals, gaskets and bearing kits a shop needs to finish a unit, at a warehouse discount price.

When a whole unit makes more sense

Pro Gear has been in business since 1997. Along with parts, we keep a large inventory of ready-to-ship exchange transmissions and offer a rebuilding service for your transmission, with the rebuilt unit delivered to any US city or worldwide. See rebuilt Mack transmissions for the units we rebuild. We also buy and sell transmissions, so call if you have a unit to sell.
