Rob Stephan shows us how well a trans-brake can benefit a turbocharged car at building boost on the startline. The Holden VL Calais RB30 turbo hasn't been ou. The trans-brake or transmission brake is a system that lets the driver spin the wheels and rev up the engine to full power, holding the car stationary without stressing the brakes, and letting it. In drag racing, a transbrake is a mechanism that selectively places the transmission in first and reverse gears simultaneously, effectively holding the race car stationary as if the foot brake was applied. It is specifically used on automatic transmissions that employ a torque converter, where it is beneficial to build up hydraulic pressure before the vehicle is launched.

SPECIALTY RACING PARTS MANUFACTURER.

Tranzact of Indy is not a parts distributor. We custom manufacture and assemble all of our transmissions and supply many distributors with the parts they sell. We do carry many race oriented and custom fabricated parts. Our research and development is done at the track and we have a long history of manufacturing some of the toughest components available. Below are some of the parts we offer:

Our Transbrake Series allows you to achieve maximum torque converter stall for quicker and more consistent reaction times and 60-foot times. The transbrake acts in much the same manner as a manual clutch and prevents torque load transmission through the drivetrain before launch. Once the transbrake is released, the power is transmitted immediately to the rear tires in much the same.

Tranzact of Indy has built some of the quickest and most powerful engines in the industry. We specialize in stroker Mopar engine and all of our engines are custom built to order. Call us for all of your Mopar engine needs from stock restoration projects to blown, injected pro-mod powerplants. We handle all of the processes in-house from decking to balancing to custom porting. We handle all of the machining in-house to keep quality high and costs low. We are a WD for Indy Cylinder Head so parts are of the highest quality and reasonably priced. Please contact us for your machining and parts needs.

All valve bodies are dynoed and transbrake test shifted 10 + times and all pressure set so you do not need to ck or drop pan to set. Ultimate Bracket 727-904 Valve Body - Footbrake, Transbrake, Manual - Tranzact has combined all of their record-setting championship winning valve bodies into ONE. From the first working low band applied transbrake in 1982. This valve body can directly replace manual with no modifications as long as it is set up for manual. The low bolt-in one wire body features an internal mechanical solenoid features: • No rolling • No need for line locs • Rev Pattern • Stock casting For limited time
Torque-Flite 727 Valve Body - Manual Valve Body (Rev. Pattern) Fits 727 & 904
Pro Competition billet Trans Brake Kit (Reverse Pattern) - this is the one all try to achieve as it has the best shift 1-2 2-3 a quick hold and quick release that the car run quicker and more mph as it does not drag the shifts proven over and over.
Nitro Pro billet Brake (full low band applied) higher pressure for 2500 hp + tested our pro-mod car and has clean shifts -

Trans Brake Kit

Clean neutral brake P n/r 123 N pattern We were the first to make this pattern. We needed on our blower car this set to get the car stoped at 1/8 mile tracks as we was 178 mph and had to shut down the engine deploy the chutes pull fuel shut off in time

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.

Trans Brake Vs 2 Step

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.

Trans Brake Operation

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