🔧 Manual Transmission Builds Done Right 🔧

At OS Diesel Performance, we’re not just turning wrenches — we’re rebuilding some of the toughest manual transmissions to ever hit the road. Whether it’s for your daily driver, tow rig, or full-blown workhorse, we’ve got you covered.

We specialize in full teardown, inspection, and rebuilds on:
⚙️ ZF6-750 / ZF6-650 (Ford Super Duty)
⚙️ ZF5 (7.3L & 460 trucks)
⚙️ NV4500 (GM & Dodge classics)
⚙️ NV5600 (heavy-duty Dodge Cummins)
⚙️ G56 (’05+ 5.9L & 6.7L Cummins)
⚙️ Getrag 360 (early Dodge 12-valves)

Each build is done in-house with premium parts, proper clearances, and factory-spec torque procedures — no shortcuts, no guesswork. Whether you need a full performance build, synchro replacement, or a complete overhaul, we’ll make sure your gearbox is ready to take whatever you throw at it.

🧰 Manuals Built the Old-School Way — Strong, Precise, and Reliable.
