Gears Slipping or Shifting Roughly?

Pete Kelley’s Auto Service provides transmission repair in Phoenix for automatic, manual and CVT transmissions from our transmission shop at 9328 N Central Ave, Phoenix, AZ 85020. Since 1972, our ASE-certified transmission mechanics have handled everything from transmission service and diagnostics to clutch replacement, transmission rebuild and transmission replacement. Call (602) 759-9354.

Transmission problems don’t fix themselves. Slipping, hesitation, harsh shifts and fluid leaks are early signs of internal wear or pressure loss, and in Phoenix heat they get worse fast. The good news: many shifting problems turn out to be low fluid, a sensor or a solenoid, not a rebuild.

Not all auto repair shops take on transmission work. We do, and we start with a transmission diagnostic.

We handle transmission diagnostics, transmission fluid change, clutch repair and CVT transmission repair for Nissan, Subaru, Toyota, Honda, Ford, Chevrolet, Dodge and Chrysler vehicles.

“Save time. Save money. Fix the right thing the first time.”

Transmission Repair You Can See for Yourself

Transmission problems are the ones drivers fear most, and often the ones they’re oversold on. In this video, George shows how we diagnose a transmission before recommending a repair. Many shifting problems in Phoenix turn out to be far smaller than a full rebuild.

Every Transmission Job Starts With a Diagnosis

Before we quote anything, we:

  • Scan for transmission codes and review live data, including fluid temperature
  • Check fluid level, color and smell
  • Road-test the vehicle, cold and warm, to feel how it shifts
  • Inspect solenoids, sensors, mounts and cooler lines, including on CVT transmissions

Heat is the number one killer of transmissions, and Phoenix traffic supplies plenty of it. Sometimes a fluid service or a sensor fixes the problem; sometimes it needs a rebuild or replacement. We show you the evidence, explain every option and put the price in writing. Every transmission repair in Phoenix we perform is backed by the NAPA AutoCare Peace of Mind Warranty, 24 months or 24,000 miles.

What Your Transmission Is Telling You

These symptoms point to different problems:

  • Slipping, or RPMs that flare between gears: worn clutches or low fluid.
  • A delay shifting into drive or reverse: often a hydraulic pressure problem, from low fluid to a worn pump.
  • A burning smell: fluid that’s overheating and breaking down.
  • Whining or shuddering on acceleration (CVT): worn CVT fluid or internal belt and pulley wear.
  • A grinding gear change (manual): a worn clutch or synchronizer.

A clunk under the car may be an axle or U-joint, not the transmission. A regular transmission flush or fluid service prevents most failures, and a warning light needs a professional diagnostic. Because many transmissions are cooled through the radiator, a weak cooling system can overheat the transmission too. Our guides on how heat wears out your transmission and understanding your automatic transmission explain more. Call or schedule online, and ask about Synchrony financing for larger repairs.

SIGNS YOU NEED TRANSMISSION REPAIR

Stay alert to these common warning signs – fix them early and save on bigger repairs.

1

Gears shifting unevenly

If your car shifts roughly or skips between gears, your transmission may need attention.

2

Loud noise while shifting

Unusual noises when shifting gears can point to internal transmission wear.

3

Red fluid leaking under car

Transmission fluid leaks are a serious warning sign – they lower pressure and cause overheating.

4

Transmission warning light is on

If this light turns on, get your transmission checked as soon as possible.

FAQs

What are the signs of transmission problems?

Slipping gears, delayed engagement into drive or reverse, harsh or late shifts, a burning smell, red fluid leaks and a transmission warning light. Transmission repair in Phoenix costs far less when problems are caught early.

Many manufacturers recommend 30,000 to 60,000 miles under severe conditions. Some call their fluid “lifetime,” but heat breaks it down, and in Phoenix, regular fluid service is one of the best ways to extend transmission life.

Not every shifting problem needs a rebuild. Many are caused by low or worn fluid, a sensor or a solenoid. We diagnose first and explain whether you need a fluid service, a repair, a rebuild or a replacement.

Yes. Common CVT symptoms include a whine, shudder or hesitation when accelerating. CVTs are especially sensitive to fluid condition and heat, so on-time fluid service matters.

Engine revs that climb without the car speeding up, a clutch pedal that engages near the top, a burning smell and grinding gears. Pete Kelley’s performs clutch replacement and manual transmission repair in Phoenix, backed by the NAPA AutoCare warranty.

Transmission repair cost ranges widely. A transmission service or a sensor costs far less than a rebuild or replacement, and transmission service cost depends on the fluid type and capacity. We diagnose first and put each option in writing.
