Protrans Automotive & Transmission Specialists understands the importance of your On-Board Diagnostics. Give us a call or stop by for a complete diagnostic check up:

Check Engine Light
No one likes to see their truck's "Check Engine" light come on. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. At Protrans Automotive & Transmission Specialists, we can pull the code and diagnose the problem for you. Give us a call at 951-367-7400 or stop by the shop for our expert assistance.

Computer Diagnostics
Modern vehicles are fitted with at least one onboard computer. The computer's main function is to monitor and adjust the engine and transmission. Computer testing and diagnostics is an integral aspect to professional electronic work on modern cars. Computer diagnostics help find the root causes of major and potential automobile problems. At Protrans Automotive & Transmission Specialists, we have state of the art computer diagnostics equipment such as digital code readers, pressure test kits, circuit testers, digital tachometers and more. Call 951-367-7400 or visit our auto shop in Riverside, CA 92507 for all your vehicle's computer diagnostic needs.

Drivability
Drivability is the degree of smoothness and steadiness of your truck's acceleration. Most modern vehicles are fitted with on-board computers that continuously check the readings from various sensors. In case of drivability problems, you will receive a warning message on your truck's dashboard. To have your truck diagnosed for drivability issues, visit Protrans Automotive & Transmission Specialists in Riverside, CA 92507 today. At Protrans Automotive & Transmission Specialists, we have the necessary tools, training, and technology to diagnose and address your vehicle's drivability issues.

Engine Controls
Basically, an engine control system is an on-board computer in your truck. Like all computers, the engine controls are composed of hardware and software. Automotive engine control systems are responsible for regulating exhaust emissions, and providing increased fuel economy. To get the best out of your vehicle's incredibly powerful technology, make sure engine controls are working properly. To check if your truck's engine controls are working properly, call Protrans Automotive & Transmission Specialists today.


what our customers say

Where do i start.. Wednesday afternoon 3pm before Thanksgiving on way home to Phoenix, car goes into limp mode, got referred to Protrans. Called them they agreed to take a look. Diagnosed, parts ordered and Throttle Body replaced and road tested. So very excited to know that there are still Honest shops out there that actually care about their clients. Highly recommend Protrans.

Went in for transmission repair, after diagnosing the problem they told me I didn't need a full rebuild saving me well over $1,000.00. They found some safety issues I wasn't aware of and I had them take care of all of them. The truck is running great! Thank you Protrans.

Jeff, Matt and Hayley and the team at Protrans did an incredible job and went above and beyond for us. We had a one of a kind, 1970 Ford Chinook Motor Home that made it down to Joshua Tree from Homer Alaska. It sat during the pandemic and we finally rescued her almost 3 years later. She did not deal with the transition to desert life smoothly and was leaking badly and ran terribly. We had her towed to Riverside and found Protrans from a referral from another shop. The team at Protrans rebuilt the transmission and went through the engine to get us back on the road without breaking our budget. Jeff was good about communicating and Matt even drove over the day after we picked it up to help assess some issues that came up on the way home. Can't say enough about the professionalism, care, and service we received and would recommend them to anyone for all car repairs!
