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

My family and I love this place! Our car had a leak and started smoking the day we had to leave Riverside and we found this place through amazing reviews. They were super fast and were understanding that we had to leave town urgently. The service was amazing and everyone we met were super friendly. They are also super attentive considering they remembered us and our situation even though we only spoke on the phone about it! They were also transparent about prices and fees so you don't have to worry about hidden charges and they made sure to get our approval before proceeding. This has to be a go to place if you are within range!

My alternator went out on my car while I was driving to Arizona with my 3 dogs and a cat, to say I was stressed is an understatement and they had my car up and running before lunch time!! I can't tell you how much I appreciated the service and their kindness.. Thanks Jeff!!

They did a diagnostic on my car and found that my transmission wasnt working anymore. They also found that my transmission was still under warranty and they sent it to a nissan dealership to get it replaced for free. I didnt even know it was atill under warranty so that was nice what they did.
