A Dedicated Transmission Shop for Tempe Drivers

Tempe sits right in the middle of the Valley, and the people who live and work there put a lot of stop-and-go miles on their vehicles. Between the US-60 Superstition Freeway, the Loop 101 Price Freeway, the Loop 202 and I-10 through the Broadway Curve, a daily commute in Tempe can mean long stretches of crawling traffic in serious heat. That is exactly the kind of driving that wears out automatic transmissions.

Sun West Transmissions is a dedicated transmission and drivetrain shop on West Northern Avenue in Glendale. We are not located in Tempe, but plenty of East Valley drivers make the trip across town because they want a shop that focuses on transmissions instead of treating them as a side job. If you are searching for transmission repair Tempe AZ options, here is what to know about us and about how Tempe driving affects your transmission.

Getting From Tempe to Our Glendale Shop

Most Tempe customers take I-10 west through downtown Phoenix to I-17 north, then exit at Northern Avenue and head west to our shop at 6116 West Northern Ave. Others prefer the Loop 101 north around the east and north sides of the Valley and then cut over to Northern Avenue. Either route is freeway driving most of the way.

If your vehicle is shifting badly, slipping or overheating, think carefully before driving it across the Valley. A transmission that is already slipping can get much worse in a short distance, especially in summer traffic. Call us first at (623) 473-9800 and describe what it is doing. Our guide on driving with a bad transmission covers the warning signs.

How Tempe Driving Wears on a Transmission

Tempe has a mix of drivers: ASU students in older commuter cars, professionals heading to office parks along the Loop 202 and Rio Salado, rideshare and delivery drivers, and families with SUVs and minivans. What they share is heat and traffic. Automatic transmission fluid breaks down faster when it runs hot, and heavy stop-and-go driving keeps fluid temperatures high because the torque converter generates heat every time you creep forward.

• Short trips and campus driving rarely let the fluid fully warm up and then cool properly, which can let moisture and varnish build up over time.
• Freeway congestion on I-10 and the US-60 means long periods of low-speed slipping in the converter, which raises fluid temperature.
• Rideshare and delivery work stacks up miles quickly. Our page on transmission care for rideshare drivers explains what to watch for.
• Summer heat on top of all of it shortens fluid life. Read more in how Arizona heat affects your transmission.

Common Transmission Problems We See from the East Valley

The symptoms that bring Tempe drivers to us are usually familiar ones: a delay when shifting into drive or reverse, a flare in RPM between gears, harsh shifts, a shudder at highway speed, or a check engine light with the transmission going into limp mode. Many late-model cars with continuously variable transmissions also come in with whining, hesitation or a loss of power on hills.

Every one of those symptoms has more than one possible cause. A shudder might be a torque converter clutch issue or simply worn fluid. A delayed engagement could be low fluid, a weak pump, worn seals or an internal clutch problem. That is why we start with a real diagnosis instead of guessing. Learn how we approach it on our transmission diagnostic testing page.

What We Do for Tempe Customers

Diagnosis First

We road test the vehicle when it is safe to do so, scan for transmission and engine codes, review live data such as fluid temperature and slip readings, and check the fluid level and condition. Only after that do we recommend a repair, and we explain the reasoning in plain English.

Repair, Rebuild or Replace

Some problems are fixed with a fluid service, a solenoid, a sensor or a software update. Others need a full transmission rebuild or a replacement unit. We walk you through the options, including the trade-offs covered in our rebuild vs. replace guide.

Clutches and Drivetrain Work

Beyond automatics, we handle clutch repair, transfer cases, differentials, driveshafts and diesel transmissions, so trucks and manual-transmission cars are covered too.

Warranty, Estimates and Financing

Estimates are free. Qualifying transmission rebuilds and replacements come with a 3-year / 40,000-mile warranty with no deductible on covered repairs. You can review the details on our warranty page. If the repair is a bigger expense than you planned, ask about our financing options.

Repair costs depend on the vehicle, the transmission model and what we find once it is inspected, so we give you a written quote rather than a guess over the phone.

Tips to Protect Your Transmission Until You Can Get In

• Check the fluid if your vehicle has a dipstick, and look for red or brown spots where you park.
• Avoid heavy acceleration and towing until the problem is diagnosed.
• Do not keep driving if the vehicle slips badly, will not move, or smells burnt.
