At Protrans Automotive & Transmission Specialists, we understand the terror that comes with the words "transmission repair." We want you to know that there is hope after all. Whether manual or automatic, heavy duty or low range, the transmission is a vital part at the center of your vehicle's drivetrain. Your transmission is instrumental in turning the engine's power into forward movement, so it's not surprising that problems with this important component can cripple your car. The experts at Protrans Automotive & Transmission Specialists have years of experience working on transmissions of all types and sizes. When everything grinds to a halt we have the skills to get you moving forward once more.
One of the easiest ways to avoid a large transmission repair bill is to flush the fluid according to the vehicle manufacturer's guidelines. Your transmission contains a lot of intricate moving parts which can deteriorate quickly if not properly lubricated. Protrans Automotive & Transmission Specialists's technicians can take a sample of your transmission fluid and determine how long it will be before it's time to renew. When that time comes, we can have you in and out of the shop quickly.
Sometimes our technicians don't get to look at the problem until after something has gone wrong. While this is certainly more serious than a simple transmission fluid change, it doesn't have to spell disaster.
At Protrans Automotive & Transmission Specialists, our expert technicians can:
- Carefully disassemble your transmission
- Identify any faults
- Determine whether repairs can be made or not
We utilize an extensive network of parts suppliers, manufacturer knowledge, and expert repair skills to get your transmission repaired, and your vehicle back on the roads of Riverside, CA.
Our Transmission Services Include:
Automatic Transmission
Automatic Transmissions shift between gears automatically to optimize driving. They change gears based on the driver's throttle pedal, vehicle speed, engine speed and vehicle load. Typical automatic transmissions have four to five forward gear ratios, a Reverse, Park, and Neutral gear. Gear shifting occurs automatically once the car is in Drive. There is no need for a clutch pedal or gear shift like there is in a Manual Transmission.
Automatic transmission repair is complicated based on all the components that are in a transmission. You need to have any automatic transmission issues properly assessed by an auto mechanic. Call 951-367-7400 to talk to the technicians of Protrans Automotive & Transmission Specialists about your transmission problems.
Clutches
There are clutches in both automatic and manual transmission cars, and different types of clutches. When shifting gears, the clutch engages and disengages from the flywheel and transfers the torque through the transmission. Clutches should help your vehicle start and shift gears smoothly. The clutch in your car receives a lot of wear and can eventually wear out. If your clutch begins slipping irregularly or making noises that are raising suspicion, contact Protrans Automotive & Transmission Specialists to see if clutch replacement is necessary.
Four-Wheel Drive Transmission
A four-wheel (4x4) drive vehicle has differential gears, both front and rear axles, and a transfer case attached to the transmission. Four-wheel drive vehicles demand maintenance on the transfer case, front differentials, rear differentials, and transmission fluids. Visit us on 3420 Gato Ct for service on your four-wheel drive transmission.
Front-Wheel Drive Transmission
If your vehicle has front-wheel drive, the engine drives the front wheels only. The power is routed through the transmission to the final drive where it is split and sent to the two front wheels through the drive axles. The engine, transmission and additional hardware are all located in the front of the car. If you are in need, Protrans Automotive & Transmission Specialists of Riverside, CA will gladly repair front-wheel drive transmission vehicles.
Manual Transmission
Driving a vehicle with a Manual Transmission requires using the clutch pedal and gear shift to manually shift gears. Manual transmissions have been built with anywhere from two to eight gears. Front-wheel drive and rear-wheel drive are the two main configurations for manual transmissions. Typically, manual transmissions require less maintenance then automatic transmissions. At Protrans Automotive & Transmission Specialists, our auto mechanics can diagnose your vehicle and then recommend the transmission repair or transmission service you need to ensure safety and improve the lifetime of your vehicle.
Transfer Cases
A transfer case is a part of a four wheel drive system found in four wheel drive and all wheel drive vehicles. The transfer case receives power from the transmission and sends it to both the front and rear axles. This can be done with a set of gears, but the majority of transfer cases manufactured today are chain driven. The transfer case is connected to the transmission and also to the front and rear axles by means of drive shafts. Trust the automotive experts at Protrans Automotive & Transmission Specialists for all your transmission repairs.
Transmission Replacement
In motor vehicles, the transmission usually refers to the gear box. The gear box uses gears and gear trains to transmit speed and torque from a rotating power source to another device. You can have your car's transmission replaced with a new, rebuilt, remanufactured, repaired or used transmission. For more information contact Protrans Automotive & Transmission Specialists in Riverside, CA. Our experienced service technicians can help you make the best decision for your vehicle and your wallet.
Transmission Service, Diagnose and Repair
Transmission repair is not something to take lightly. The transmission is connected to key parts of your vehicle and needs to be working properly for your safety. Transmission services include replacing filters and draining fluids to prevent transmission damage. Typical transmission issues that may lead to repair may include shifting issues, slipping, stalling, fluid leaking, and the service light turning on. If you are concerned that you may need transmission repair, don't hesitate to schedule an appointment at Protrans Automotive & Transmission Specialists today.

In addition to these services, here is more information about transmissions and their parts.
At its most basic, your car's clutch allows the engine and gearbox to engage and disengage from each other between gear changes. This means that although the engine's output shaft is still spinning, there is no load on the gears which may cause them to shift improperly. Once the next gear is smoothly selected your clutch will re-engage the engine and gearbox, resuming forward momentum.
Over time, and especially in improperly operated manual transmission vehicles, the clutch can become worn and less effective at its job. A damaged clutch can allow the engine and gearbox to re-engage mid-gear change. This can have serious effects on the health of your transmission. Protrans Automotive & Transmission Specialists determines the health of your clutch through diagnostic testing as well as test driving. As with a transmission fluid flush, we'll have your car back on the road and your peace of mind stretching for miles.
Another area of our gear-based expertise is your car's differentials. These sit in the middle of your car's axles between the wheels and are vital for a smooth ride. As you turn a corner, the outside wheel has to travel a greater distance than the inside wheel. Without properly functioning differentials, the wheels would turn at the same rate. This would cause your car to vibrate horribly and struggle to turn whenever you tried to go around a corner.
When it comes to examining, diagnosing, and fixing faulty differentials, our experience with transmissions makes Protrans Automotive & Transmission Specialists the best place to go in Riverside, CA.
Avoid transmission disaster by coming in and having your transmission, clutch and differentials checked out today. Call us at 951-367-7400 or visit us in Riverside, CA so we can schedule an appointment to ensure your car is in tip-top shape!
Transmission Fluid FAQs
What are signs that you need to change your transmission fluid?
The most obvious sign that it's time to change your transmission fluid is a warning light on the dashboard. Other signs may include engine revving when accelerating or turning, difficulty shifting gears, a chattering noise when you start driving, a slight burning smell, or fluid leaking beneath the vehicle. If you're uncertain about a noise, leak, or unusual driving condition, bring your vehicle to Protrans Automotive & Transmission Specialists in Riverside for an inspection.
How often do you really need to change transmission fluid?
The recommended interval depends on the type of transmission. Most automatic transmissions require a fluid change every 60,000 to 100,000 miles. Manual transmissions generally need fresh fluid every 30,000 to 60,000 miles. Following your manufacturer's maintenance schedule is the best way to maximize transmission performance and longevity.
Does a car run better after a transmission fluid change?
Yes. Replacing old transmission fluid can help improve transmission performance, promote smoother shifting, and reduce unnecessary wear on internal components. A properly functioning transmission also reduces strain on the engine, which can contribute to better overall vehicle performance and fuel efficiency.
What is the average life of a transmission?
Regular fluid changes, filter replacements, and routine maintenance are essential for maximizing transmission life. Most modern automatic transmissions can last between 100,000 and 200,000 miles when properly maintained. Manual transmissions often last even longer and may exceed 250,000 miles with proper care.
Which type of transmission lasts the longest?
Manual transmissions generally have fewer moving parts and often require less maintenance than automatic transmissions. They are also less dependent on specialized fluids and electronic controls. As a result, vehicles equipped with manual transmissions frequently achieve longer transmission lifespans when properly maintained.

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.
Ray Zambrano
Very polite and professional people and prices that were reasonable also. They also followed up to see how I liked their work. They rebuilt the transmission on my H2 Hummer. Everything seems great, and nice people to deal with.
