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

We've been going to Pro Trans for over 20 years & always have good experiences. I want to thank Michael for his personal service all these years. They've replaced engines & transmissions in two of our vehicles. There is no job too small or too big, so far. They don't even mind working on our raised truck with a 6 inch lift! Thanks again for your the great work!

I was nervous about finding a shop to work on my truck since there are so many shady mechanics out there, but Protrans ended up doing an amazing job. They were great about communicating with me throughout the whole process as well. I believe I paid a fair price for the repair and they didn't try to sell me a bunch of service that I don't need. I will certainly be using them in the future if I need to.

The crew at Protrans replaced my fuel tank after thrives drilled a hole in my existing tank and had my truck back to me in a day and a half. Thanks again!

The team at Protrans are professional and service minded. They performed a synthetic oil change on my sister's Chevy Cruze swiftly and seamlessly. It was my first time using this company and I will definitely be going back. A shout out of thanks to Jeff, Manny, Haley and the the entire Protrans team!
