Services
Transmission Repair
We specialize in automatic transmission repair for cars, trucks, and SUVs. Our process includes diagnostics, component replacement, and performance upgrades. Each repair includes updated shift kits and new electronics for improved reliability and driving experience.
Torque Converter Rebuilding
Custom torque converter fabrication with hardened components. We use solid rivets, tig welding, and billet back bowls to create 100% stronger converters than stock. This ensures improved stability and longevity for high-performance applications.
Hot Flush Machine Service
Our proprietary Hot Flush system cleans transmission fluid coolers using 180F fluid and air cycles. This removes debris from failed transmissions without radiator bypassing, maintaining factory cooling system integrity while preventing future failures.
General Auto Repair
Comprehensive auto repair covering brakes, cooling systems, exhausts, and diagnostics. We service all vehicle components from front to back, including factory scheduled maintenance and computerized diagnostics for modern vehicles.
Performance Upgrades
We install heavy-duty components like converter necks, furnace-brazed turbines, and special bearing caps. These upgrades reduce wear, prevent breakage, and improve durability for vehicles used in demanding conditions or performance applications.
