All the horsepower in the world is useless if it cannot reach the road. The driveline — gearbox, clutch or converter, driveshaft, diff and axles — is what turns power into motion, and it has to be built to match what the engine makes.
We rebuild original transmissions, convert tired automatics to crisp modern overdrives, swap in five- and six-speed manuals, and build differentials and axles that survive hard launches without complaint.
Driveline services
From a faithful original rebuild to a full modern conversion, we make sure every link in the driveline is up to the job and a pleasure to use.
- Manual and automatic transmission rebuilds
- Overdrive automatic and 5/6-speed manual conversions
- Clutch, flywheel and torque-converter matching
- Differential rebuilds, gear ratio and limited-slip
- Custom driveshafts, balancing and U-joints
- Axle upgrades for high-power applications
Cruise easy, launch hard
An overdrive gear transforms an old muscle car on the freeway — lower revs, less noise, better economy and a relaxed cruise. Pair it with the right rear gear and converter and you get effortless highway manners with savage off-the-line response.
How We Work
Assess
We inspect the whole driveline and match it to your power and use.
Build
Transmission, diff and driveshaft rebuilt or converted to spec.
Integrate
Clutch/converter, gearing and shifter matched for feel.
Test
Road and load testing to confirm shift quality and durability.
Common Questions
Can I add overdrive to my classic automatic?
Yes — a modern overdrive automatic conversion is one of the best upgrades for a cruiser, cutting highway revs dramatically.
Will a manual swap need other changes?
Usually a pedal box, crossmember, driveshaft and clutch hydraulics. We handle the whole conversion as one job.
My diff whines — can you fix it?
A whine usually means worn gears or bad setup. We rebuild diffs and set backlash and pattern properly to fix it for good.
