Transmission Service in Washington UT
Automatic and manual transmission service for any car, truck or SUV. Towing and off-road use accelerate the wear.
MST Motorsports provides professional transmission service in Washington, Utah for cars, trucks and SUVs, including Ford, Chevrolet, GMC, Ram, Jeep and Toyota. Automatic and manual transmission, transfer case and differential service is performed by our factory-trained, certified technicians. Towing, off-road gear cycling and sustained load on SR-18 grades put transmissions under stress that highway-only vehicles never see, and regular fluid service keeps that wear from becoming a major repair. Qualifying repairs are backed by our 36-month/36,000-mile nationwide warranty.
Transmission & Drivetrain Services
Transmission Fluid Service
A transmission fluid change by drain-and-fill or full flush, depending on your vehicle and service history, using the OE-specification fluid for your transmission.
Filter Replacement
Internal filter replacement on serviceable pans.
Transmission Diagnosis
Transmission diagnosis uses scan-tool live data, pressure testing and physical inspection to trace slipping and shift problems to the root cause.
Manual Transmission Service
Manual gearbox fluid service, clutch inspection and hydraulic system service.
Transfer Case Service
4WD transfer case fluid change and mechanical inspection, an often-overlooked service that matters on trucks and Jeeps.
Differential Fluid Service
Front and rear differential fluid service, which is critical for towing, off-road and 4WD platforms.
Towing & Off-Road Use
Towing and off-road use shorten transmission fluid life because automatic transmission fluid oxidizes with every heat cycle. A tow up SR-18 with a UTV trailer or a run down the Virgin River Gorge with a fifth wheel is a heat cycle.
We review the manufacturer's severe-service requirements for the specific vehicle, transmission and use. Those requirements, service history and inspection findings guide the transmission service plan.
Warning Signs
- Delayed engagement when shifting into Drive or Reverse
- Slipping between gears or under load
- Rough, harsh, or clunky shifts
- Fluid leaks on the driveway
- Burning smell — overheated fluid

Frequently Asked Questions
How often should transmission fluid be changed?
Transmission fluid and filter service follow the requirements for the specific transmission and vehicle, including applicable severe-use guidance. We review the service history and fluid condition, and diagnose shift or temperature complaints before recommending work.
Does towing affect my transmission?
Towing can increase transmission heat and load. We review the vehicle and transmission manufacturer requirements for the trailer loads and driving conditions, including applicable severe-use guidance. Fluid service and any cooling-system changes are recommended for the truck and its actual use.
Do you service transfer cases?
Yes. We service transfer cases on 4WD trucks, Jeeps and Broncos, including NP, BorgWarner, Magna and OEM-branded units. Fluid type, inspection and replacement timing follow the vehicle and transfer-case manufacturer's requirements and service history.
