Are you shopping around for a GM high-performance transmission? You are welcome since this is the right place to get one. Gearstar is highly committed to engineer and builds the most satisfactory GM and Chevy high-performance transmissions that are hand-built and customized to handle as much as 1000 ft.-lbs. torque and 1200 horsepower.

Each high performance is put together by one technician – from scratch, i.e., from start to finish – using premium-quality parts on the market today. The transmissions are perfectly engineered and built to the horsepower, rear gear ratio, and torque specs of every engine it will be matched with. 

Every high-performance transmission undergoes a thorough dynamo test for up to 1000 miles to validate its excellent working condition before leaving the Gearstar facility. Each driveline component is built with the highest quality constituents, including the latest updates.

Why Refer to a Transmission as ‘High Performance’?

A high-performance transmission is usually – and much more likely – utilized for engineered and built engines for performance and speed. 

This gear mechanism used to be limited to only vehicles used exclusively for racing on the drag strip or street racing. However, over the years, there has been a lot of blurring of the line.

Many car enthusiasts these days are no longer reserving specific vehicles for those times. They are now outfitting their unique daily drivers to make them versatile enough to conform to numerous roles.

This often implies restoring and modifying their existing muscle automobiles to meet both objectives – i.e., be a reliable daily driver during the day and tear up the street or track by night or on weekends.

Matching the Engine and High-Performance Transmissions

It is vital to match your vehicle’s transmission to its engine; therefore, do not spend too much money on modifying the engine.

This is where high-performance transmission comes on the scene. To fully utilize your car engine, you must get the converter and transmission to back it up. 

High-performance transmissions provide both the speed and power that you need to get or reach peak performance, thanks to your racing engine. This includes other high-performance types of engines.

This is why you need to ensure that your high-performance transmission builder and engine builder agree or are on the same page from the beginning of the project until it is completed. 

When you are crystal-clear upfront about what you expect regarding speed, power, durability, and performance, the two builders can work together and produce the results you need in record time.

This makes Gearstar different, as you will always get the specs you request without any alteration.
