Tired Of OEM Replacement Transmissions?

The legendary Cummins motor powers Dodge trucks, but they are equipped with a less-than-stellar OEM transmission. You need a transmission to handle the abuse the Cummins motor can dish out. We also service, rebuild, install, and repair Ford Powerstroke diesel trucks and GM’s Allison Transmissions powered by Duramax Diesel engines.

If you’re tired of OEM replacement transmissions, today’s after-market transmission packages have the quality and engineering to meet your needs, from towing to racing. With industry-leading technology and new manufacturing techniques, you can find (virtually anywhere) after-market transmissions perfectly matched to the OEM diesel engines of your Dodge Cummins Truck, Ford Powerstroke, or Allison-equipped GMs.

Don’t ask the other guys; ask the experts here at Performance Transmissions convenient to Dallas, Fort Worth, in the great state of Texas who have been your after-market specialists for diesel transmissions for more than 30 years. Because . . . power must go to the ground. The diesel owner knows that means something when they find their trucks in stock form too powerful due to their high horsepower applications with transmissions that don’t stand up to everyday commutes or pulling heavy loads. Those customers come to us in droves, realizing that the reliable parts for the best diesel performance should take power loads and transmit it to the rear wheels [hence, to the ground] but are failing to do so, tearing up transmissions left and right.

With Performance Transmissions, you can choose from smooth, quick, crisp shifts for on-the-street use when attached to a heavy load or hardcore power builds that shift hard and fast, sacrificing little time and leaving nothing behind.

We strive to accommodate all types of trucks and the problems that can happen with them, whether full-sized trucks or small pickups that need repairs. If you’re looking for a high degree of maintainability, we have the knowledge needed, and we’re certain we’ll be able to pinpoint your truck’s issue if it needs repairs.

From brakes to tires, driveline repairs to electrical work, the professionals at Performance are here to ensure that your vehicle gets the attention it needs to stay in prime working condition. We’re equipped to run a variety of diagnostic tests, are confident in our maintenance and repair services, and are intent on getting you back on the road as quickly as possible.

When it comes to your favorite toy, it takes a lot to keep it running at its full potential. All of our automotive techs are ASE certified. From basic services like brakes to more complex needs like glow plugs and fuel filters, Performance works hard to ensure that you get the right service for your vehicle. We encourage anyone to stop by our shop with their service or maintenance needs and see why our customers are customers for life.

What Makes Performance Transmissions Different?

Bring your heavy duty transmission repairs to Performance Transmissions. We will review what is wrong and look at anything else you have working with your transmission that might not be specific to your application and HP needs. The last thing we want to do is perform your diesel truck transmission repair or replacement and then have you back in our transmission shop later that same day for something we could have prevented ahead of time. That is too much of a risk to our customers and their important jobs. We inspect your diesel truck transmissions and ensure you know everything is wrong before we proceed with the repairs. Those repairs are then followed up with testing to make sure your heavy duty truck transmission has the proper torque for the job you need your vehicle to do. You can trust in the experience and skills of putting your vehicle in our capable hands and know that your diesel truck transmissions will work better after the repairs than in a very long time.
