Trans Brake Racing Transbrake Kits Transmission Brake Valve Body

 

The trans brake revolutionized drag racing automatic transmission equipped vehicles. A transmission brake allows your vehicle to launch off the line with more "hit" to the suspension and tires. If you want the hard hitting initial move off the starting line like what you get by dumping the clutch on a manual transmission, but with the ease of use of an automatic transmission then an automatic transmission brake valve body is what you need. If you would like a further definition of what a transbrake is and how it works, please click here.

If you are looking for a manual shift valve body but do not want a trans brake, please view our manual valve body products here.

JW Performance Transmissions, Inc. builds the best quality transbrake valve bodies available. We offer their entire line of dependable, hard hitting transmission brakes. When using electronics like a delay box, you make the best use of them by using the delay box with a trans brake.

Automatic Transmission Adjustment, Tips and FAQ

 

Q: What is a trans brake? How does a transbrake work?

A) An automatic transmission transbrake is a modified or aftermarket valve body which puts the trans into first gear, and reverse gear at the same time. This is done in part by applying electrical voltage and current to the valve body assembly. As long as power is supplied to the valve body the vehicle will not move. This allows the engine to be brought up to a higher rpm than what is possible when "foot brake" racing. When the brake is engaged, there is no torque being applied to the driveshaft, so the suspension is also in an unloaded state. When current is removed from the brake, the reverse component of the trans is released, and torque is applied to the driveshaft very abruptly. This "hits" the tires harder, more like what a manual transmission car does when the clutch is released. Since the transbrake is controlled by applying an electrical current, it is also the preferred method of controlling when the car launches when using delay boxes and other modern drag race electronics.

A transmission brake can be used in a street vehicle, but is most commonly used for serious drag racing.
