Transmission

Any equipment is only as strong as its weakest link and nowhere is that truer than with high-performance cars and trucks. Put a lot of horsepower under the hood without upgrading the transmission and driveline and you're sure to end up on the side of the road with busted parts. When your hunt for tremendous power and torque gains turns to upgrading your transmission and shifting performance, choose hardcore tune-ups for your race, street/strip, hot rod, or street rod. With our performance transmission and driveline components, you'll be able to get all that power to the ground reliably.

OEM transmissions, flywheels, clutches, and torque converters are fine for commuting with a stock engine, but they're not up to the job for performance driving with a breathed on mill. Each component plays a part in turning engine power into traction, and each has to be beefed up to handle the additional stress from extreme horsepower and massive torque boosts. All of the parts we carry are from the top brands, and they've been engineered with the precision needed for imprecise environments to deliver the durability and peace of mind you need when the engine is revved to the max.

A super powerful engine is perhaps the first thing that comes to mind when thinking about a high-speed vehicle. In practice, even the most advanced engine can't get your automobile moving without the hard ‘backstage' work of the transmission. Its often neglected components are extremely crucial to your engine's effective performance and power output. The transmission gears, for instance, provide the additional leverage required for faster acceleration, which in its turn results in more torque. Once there is an increase in torque, you can enjoy added horsepower in the lower RPM range for much quicker starts and better towing. In other words, your transmission system is the sort of a magnifier for the engine's twisting force.

If you're striving to upgrade your transmission, there are two ways to go about this. You can either improve the one you already have on your vehicle for greater efficiency and capacity or choose a whole new modern system to get significant gains in performance and fuel efficiency. The most common upgrades are shift-improvement kits, high-strength bands, clutch packs, and products alike that can add up to a very substantial performance gain at one stroke. Fine-tuning transmission internals will enhance custom- and close-gear ratios, shift quality and functions, as well as overall strength to allow the transmission to withstand the harshest environmental conditions. So, whatever reason you want to modernize your transmission, JM Auto Racing will help you tackle the task!
