Transmission Service & Repair in Twin Falls, ID — S&D Automotive

‍ ‍Transmission work has a reputation for being expensive — and it can be. But most transmission problems start earlier, with a fluid service that got skipped or a symptom that got ignored. At S&D Automotive in Twin Falls, we handle transmission work from routine fluid service to complete rebuilds and replacements. We diagnose before we recommend, explain what we find in plain language, and give you a straight picture of your options before asking for a decision. We've been doing this since 1990 and we've seen what happens when transmission problems get delayed.

Signs Your Transmission Needs Service

Transmissions rarely fail without warning. These are the signs to catch early:

• Slipping between gears — engine revs up but acceleration doesn't follow

• Delayed engagement when shifting from Park to Drive or Reverse

• Rough, hard, or jerky shifting

• Transmission warning light or check engine light with a transmission code

• Whining, buzzing, or humming noise that changes with vehicle speed

• Burning smell — burned transmission fluid has a very distinct smell

• Fluid leak under the vehicle — transmission fluid is typically reddish and slippery

• Vehicle won't shift out of a gear or gets stuck in a gear

Any of these symptoms warrant a diagnostic check before they develop into a full transmission failure. The difference between a $300 fluid service and a $3,000 rebuild is often just how long you waited.

Our Approach to Transmission Work

We start with a proper diagnosis before recommending any repair. Transmission fault codes narrow down the issue significantly — slipping, solenoid faults, and pressure faults all point to different solutions. We don't recommend a rebuild when a fluid service will fix it. And we don't recommend a fluid service when the transmission is mechanically compromised.

If a rebuild or replacement is needed, we'll walk you through the options clearly: rebuilt unit, remanufactured unit, or used transmission with warranty. You'll know what each costs and what each comes with before you make a decision.

Transmission FAQ

It ranges enormously depending on the problem. A fluid service or solenoid replacement is a few hundred dollars. A rebuild or replacement is significantly more. We always diagnose before quoting so you know exactly what you're paying for and why.
Yes. Transmission fluid degrades over time and loses its protective properties. Most manufacturers recommend a service between 30,000 and 60,000 miles for automatic transmissions. Waiting until there's a problem means the fluid has already caused wear.
Often it can be repaired. It depends on what's failed. Solenoids, seals, sensors, and even clutch packs can be serviced without a full rebuild. A proper diagnosis tells us what's actually broken.
A rebuild involves disassembling your existing transmission, replacing worn components, and reassembling it. A replacement swaps your unit for a remanufactured one. Both can be good options depending on the condition of your transmission and the mileage of the vehicle.
Yes. Manual transmission service, clutch replacement, and flywheel resurfacing are all within our scope.
