When your fleet is built for serious work, hauling, grading, loading, or digging, you can’t afford to have a transmission let you down. In the world of heavy-duty vehicles, your gearbox is your backbone. And when it starts slipping, overheating, or stalling? You need it fixed fast and fixed right.
That’s where Vortex Transmissions comes in. We specialize in heavy-duty automatic transmission services and repairs, designed for the real demands of South Africa’s working fleets.
Why Transmission Services Are So Critical
Heavy-duty vehicles operate under pressure. Whether you’re managing construction equipment, agricultural machinery, or OHVs in mining, every gearbox has to:
- Handle high torque loads
- Run for long shifts without rest
- Survive extreme conditions – heat, dust, inclines, and stops
A failing transmission doesn’t just slow down your vehicle; it risks an entire job site grinding to a halt.
That’s why our services don’t just repair problems, we prevent them.
Advanced Diagnostics for Better Accuracy
At Vortex, we use dyno testing and valve body calibration to get to the root of transmission problems fast.
- Dyno Testing: Simulates real-world conditions to check power output, gear shift smoothness, and performance under load.
- Valve Body Calibration: Tunes the hydraulic brain of your transmission to restore proper shifting and pressure management.
These tools help us identify issues before they become failures, and they ensure every rebuild we do performs at OEM standard or better.
