Whether you need a dependable factory rebuild, a performance-focused upgrade, or targeted valve body repair, we deliver fast, honest, and high-quality work, backed by real experience.

​

Factory Rebuilds:

​

Our factory-style rebuilds restore your transmission to OEM specifications using premium parts and expert craftsmanship. Every unit is disassembled, thoroughly cleaned, inspected, and reassembled with new seals, gaskets, clutches, and soft parts. We test every rebuild to ensure smooth, reliable operation, no shortcuts, no guesswork.

​

Performance Upgrades:

​

If you’re pushing more power, towing heavy, or just want a stronger setup, our performance upgrade packages are built for you. We offer custom clutch packs, valve body recalibration, billet internals, and heavy-duty components designed to handle increased torque and heat. From daily drivers to high-horsepower builds, we build it right.
