A vehicle’s transmission is one of its most essential components. It is responsible for transferring power from the engine to the wheels.
In simple words, a car transmission, also known as the transmission system, is the mechanism that transfers power from the engine to the driving wheels. This vehicle component is crucial in determining the power and functionality of your engine systems. Automatic Transmission and Manual Transmission are the two types of transmissions.
A vehicle’s transmission system can be classified into the following:
The original type of transmission is manual transmission. It is also known as the standard transmission, but chances are you have heard the term stick shift. The driver of this transmission uses a clutch to control torque transfer from the engine to the transmission, manually shifting between gears as needed.
Also, manual transmissions are the simplest type of transmission mechanically and often last longer than other types. There is less that can go wrong. The manual transmission’s only major disadvantage is the learning curve; these vehicles require more concentration and maneuvering than other transmissions.
A manual transmission requires the driver to select the appropriate gear and engage or disengage the clutch. To engage and disengage the engine from the transmission, the transmission employs a flywheel, pressure plate, and grip. The clutch is splined to the transmission input shaft and is sandwiched between them. Pushing in the clutch means releasing the pressure plate, which disconnects the grip from the engine.
An automatic transmission is a type of transmission or gearbox that can change gears automatically while the vehicle is in motion. Manufacturers also refer to it as auto, AT, or the self-shifting transmission. It is also referred to as an ‘n-speed’ automatic, where ‘n’ represents the number of forward gear ratios. It is a vehicle transmission type that eliminates drivers’ need to shift gears manually or independently.
CVT’s, continuously variable transmissions, are pulley-based transmissions commonly found in small vehicles with small engines. For many years, CVT’s have been used in snow machines, ATV’s, and side-by-sides. They have also recently become popular in hybrid cars.
A small primary drive and a secondary sizeable driven clutch are used, with a belt or chain connecting the two. At a stop, the belt or chain will be low in the primary drive and high in the secondary purpose.
As you speed up, the primary drives contract, causing the belt or chain to walk up, while the secondary expands, causing the belt or chain to step down.
The term transmission refers to the gearbox, which uses gear and gear trains to convert speed and torque from a rotating power source (engine) to another device (wheels). Transmission fluid is used to lubricate the transmission components for optimized performance.
Here are some of the top reasons that indicate your vehicle’s transmission system needs repair:
If your vehicle refuses or struggles to change gears, you are most likely dealing with a transmission problem. Low or erroneous transmission fluid types could cause your vehicle’s refusal to shift gears.
If you notice any burning odors coming from your vehicle, you should take them to a mechanic immediately.

Clean, knowledgable, experienced and professional. Prices were more than fair and they were a pleasure to work with on rebuild of my Ford Transit Connect's transmission. Planning on having them repair my GMC diesel next.

Truck running in limp mode. Message to service exhaust system now. Called and they told me to bring it in. This was on a Friday. By Monday it was diagnosed as a diesel particulate filter plugged up. Regen did not solve the problem. Suggested replacement of entire exhaust after treatment system. I ok’d the work. Took two weeks to get the scarce parts. Great word great people to work with. Highly recommend this shop.

This was my first time visit at Protrans Automotive, I did not know what to expect and was worried about how bad my car was and what it would cost me. Jeff greeted me and was very professional and welcoming. While my car was being repaired, I made arrangements to rent a car at a rental place, which was about 1/2 mile away. I was offered a ride to the car rental place by Protrans, which was really nice and accommodating since the weather was very frigid that morning. That afternoon, Jeff called me and advised my car was ready and it was not nearly as bad as I had anticipated. I was pleased with their hospitality and professionalism. I am happy with my car and it is running great!!! Thank you for your great service.

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.
Jerry Griffus Nov 11, 2022
Very friendly! They checked our car and gave us professional recommendations for free! Will surely go back to them when next oil change needed.
Yuan-Lu Chen Nov 11, 2022
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 MotorHome that made it down to Joshua Tree from Homer Alaska. It sat during the plandemic 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!

Good Day; The service at "Protrans" was "Top Notch " ! Before I took my car to "Protrans", I took it to another service center and I was told that it needed a Transmission Replacement to the tune of $3,500.00. I then took it to "PROTRANS" for a second opinion and their tec found that all that was needed was for the front wheel bearing to be replaced. That was a savings of over $3,000.00 dollars 💵. So if you need ANY work done on your automobile I would have "PROTRANS" ✔ it out first. T. Van Dorn

Felipe Avila Jul 7, 2022
Brought my 01 accord in and they were extremely courteous, quick and efficient with their services. I honestly wouldn’t recommend any other shop in the riverside area besides them. 10/10 you literally can’t go wrong choosing them!
Keanu Ivey Jul 7, 2022
A honest and dependable place to take your car.
Gloria Lopez Oct 10, 2021
Very grateful and impressed with Hayley Jeff and Mike at ProTrans. Dealer quoted $3000 for a new transmission. Took it to ProTrans for a second opinion. They honestly called and reported that it was just an issue with the driveshaft and $150 later I was out the door. I appreciate the honesty and integrity of Jeff and this company. Would highly recommend and would return!

If you’re looking for an honest and affordable automotive service, this is the place. I took my 2010 Ford Focus and they fixed my issue at a reasonable price and provided recommendations to enhance my vehicle. I did take the recommendations and my car runs like new. They have great customer service and now I’m a loyal customer!
Steven Pacheco Jul 7, 2022
Very professional outfit there. These guys did great work on my Kia. I know those parts were hard to find too. My car has never run better. Highly recommend this place...Just an update I was called by the owner I believe a month ago. He was checking in to make sure everything was still OK. Thanks. You definitely don't see that kind of follow up, and customer service much. You guys are great.
Thomas Apr 4, 2022
I told my mom (Anna) that this place seemed like a great place based off the reviews. Let me tell you these people are amazing they fixed the transmission to our 2012 Kia over a month ago and the car is still doing great just passed it smog test. They were incredibly kind to my mother and sympathetic to our situation they even gave her a ride home. They worked quickly we would have gotten our car a day earlier than we did but our phone number was incorrect but never the less I would highly recommend them.
Sophie Jul 7, 2022

Roy Hornaday Jun 6, 2022

Nasser Dahdul Aug 8, 2020
Had an 2 quart over fill from another business that caused a leak on my transmission Protrans fixed the leak and brought the fluid down to where it's supposed to be, I thank the people at Protrans for helping me get my truck to where it's supposed to be before any damage could be done !!
