Master AutoTech West Valley diagnoses, services and repairs automatic and manual transmissions for drivers across West Valley City, Kearns and Magna. We tell you whether you need a fluid service, a repair or a rebuild before any work starts, and back the work with our 12-month / 12,000-mile warranty*.
Stop-and-go traffic on 3500 South and the climb up the canyons heat transmission fluid and wear it out faster. Our shop is on 3500 South between 4000 West and 4400 West, so we’re easy to reach before a small shifting problem turns into a rebuild.

What West Valley City Drivers Say
“These guys at this Master Muffler are absolutely the BEST!!!! I 100% trust their judgment when it comes to cars. I brought my last car to them and they took incredible care of it. I was looking to buy a used car and every car I brought them, they checked and told me if it was a good quality car or not. I highly recommend if you don’t have a mechanic you trust, to come see Jacob!”
Jocelyn B
“I’ve brought in two vehicles in the last week. The first is my business van for which they tested the catalytic converters and found one to be completely blocked off. After replacement the engine breathes like it should and pulls stronger than I ever remember it being. My second vehicle is a 2002 Toyota Camry. Rather than replace the catalytic converter they were able to perform a repair to the flex portion of the catalytic converter assembly for only $147! Thank you Brent!”
Doug M.
“I love this place. It’s the only place I’ll take my car! The staff is so kind and knowledgeable, and I never feel like they are ripping me off or telling me that I need to fix things that don’t need to be fixed. They always take great care of my old car and give me the best tips for me to do what I can to keep it running too! They are always super fast and when it’s something that will take a long time to fix, they’re so good about calling me and keeping me updated on the progress! I love this Master muffler location!”

How Often Should You Service Your Transmission?
Most automatic transmissions need a fluid service every 30,000 to 60,000 miles; check your owner’s manual, because some “lifetime” fluids still benefit from changing. Towing, stop-and-go traffic on 3500 South and climbing the canyons heat the fluid and break it down faster.
| Driving condition | Recommended fluid service |
|---|---|
| Normal commuting | Every 50,000–60,000 miles |
| Towing, hauling or mountain driving | Every 30,000 miles |
| Manual transmission | Every 30,000–60,000 miles |
| CVT | Follow the manufacturer schedule closely |
Signs You Need Transmission Repair
Catching transmission problems early can mean a repair instead of a rebuild. Watch for:
- Slipping gears or RPMs that climb without acceleration
- Rough, harsh or delayed shifts
- A delay before the car moves in Drive or Reverse
- Red or brown fluid under the vehicle
- A burning smell after driving
- Whining, clunking or humming noises
- The check engine or transmission warning light
How Much Does Transmission Repair Cost in West Valley City?
Transmission costs range from a fluid service to a full rebuild, so diagnosis comes first. Price depends on the transmission type (automatic, manual or CVT), what failed, and your vehicle. Many shifting problems are solved with a solenoid, sensor or fluid service rather than a rebuild. We’ll explain every option and price before we start.
Need to spread out the cost? Master AutoTech offers several financing options, including the Goodyear Credit Card (6-month special financing on purchases of $250 or more), the Synchrony Car Care credit card, the 1stMILE Mastercard, Snap Finance, Acima, Surepay and RC Willey financing.
