Heavy-duty builds
Transmissions built for towing, hauling and hard use — upgraded internals, cooling and control.
01 Performance
Performance parts & upgrades
Factory parts are built to a price. When a vehicle tows, hauls or just deserves better, we can build the drivetrain to handle it — without turning it into something you cannot drive every day.
02 Why upgrade
Built for the job it actually does
A stock transmission is fine until you ask it to pull a loaded trailer up a grade in July. Heat and load are what kill them. The right build adds the friction material, cooling and control to survive real work.
- Heavy-duty internalsBetter friction material and upgraded hard parts where they matter.
- Heat controlCoolers, lines and fluid chosen for Texas heat and towing.
- Honest adviceIf your setup does not need the expensive option, we will say so.
03 Capabilities
What we build and fit
From a shift kit on a daily driver to a full heavy-duty build for a working truck.
/ 02
Shift kits & valve bodies
Firmer, cleaner shifts and better control — the most cost-effective change most vehicles can get.
/ 03
Higher-stall converters
Torque converters matched to the engine and to how the vehicle is actually used.
/ 04
Differential & gearing
Gear ratio changes, limited-slip and locker work, axle and differential upgrades.
/ 05
Diesel performance
Drivetrain work for the diesel trucks that do the pulling around here.
/ 06
Suspension, exhaust & parts
Lift and leveling kits, shocks, exhaust work, and installation of parts you bring in.
04 Towing
Built for the load behind you
Towing is the hardest thing most people ask of a transmission: extra weight, extra heat, long grades. If you pull a trailer, a horse rig, a boat or equipment, the drivetrain should be set up for it.
- Cooling firstExtra cooler capacity is usually the single biggest improvement.
- Right converterMatched stall so it pulls without overheating.
