How does a trans brake work on a transmission?
A transbrake is activated by a driver-controlled switch that connects to a solenoid mounted on the transmission. When engaged, the transbrake applies forward/low gear and reverse at the same time. Working against each other, the vehicle is unable to move, and is effectively locked in position on the starting line.
Can you put a transbrake on a automatic transmission?
The transmission brake has allowed automatic transmission racers to run competitively with stick shift cars. Note the separate roll control switch on the steering wheel along with the large Biondo transbrake button on the steering column.
Is a 200r4 a good transmission?
Its bellhousing, drive shaft, and mechanical speedometer make it a superior fit for vintage cars, and its sturdier build and better torque capacity make it the better non-electronic 4-speed overdrive transmission for classic GM performance builds.
What is a 2 speed trans brake?
By using the two speed design, the transmission can utilize the transbrake in second gear, allowing the car to launch a much higher starting line ratio than a powerglide. This feature is useful in high powered race cars with limited traction.
Do you need a 2 step with a transbrake?
Yes, you can use a 2-Step to help build boost, but there’s more to it sometimes besides just “putting it on the 2-Step.” Often times it takes some testing to see what RPM, igniting timing, fueling, etc., it takes to make it work well and build boost.
What cars did the 200r4 come in?
The TH200-4R was primarily used in GM rear wheel drive cars that were equipped with the 231 Buick, 301 Pontiac, and the Oldsmobile 307, 350 gas and diesel engines between 1981 and 1990. Many Chevrolet 267 and 305 V-8 engines also came with the TH200-4R transmission because of the multi-fit bell housing.
Who invented the Transbrake?
Steve was the inventor of the trans brake, lock up convertor, and first to produce a billet valve body,plus many other racing transmission innovations. Most Hemi shoot out cars still run his v body. I bought my first race transmission from him in the late 70s.
How much HP can a 200 4R handle?
The stock TH200-4R input shaft is safe to about 550 horsepower. Shown here is the end of the shaft that fits into the overrun drum at the rear of the transmission.
What kind of transmission is a 200 4R?
The 200-4R was a continuation of the Turbo Hydramatic line of GM transmissions, specifically being the successor of the TH200, a light-duty TH350 designed to improve fuel efficiency in the face of the oil embargo of 1973.
What is the difference between a 200-4R and 700R4 transmission pan?
The 200-4R pan gets smaller toward the end, whereas the 700R4 is almost a perfect square. Owing to the fact that they have very similar dimensions, the 200-4R is often mistaken for the TH350. Be aware that the TH350 has 13 bolts, and a more square transmission pan. You’ll also notice the TV Cable coming from it.
What is the best factory 200-4R transmission?
The best factory 200-4R transmissions can be found in the Monte Carlo SS and Oldsmobile 442 that were released in 1986 and 1987. They all came with locking torque converters.
What is a Level 3 200-4R transmission?
Good for motors up to 500 horse power using pump gasoline, see chart below. This level 3 200-4R transmission comes with our hardened input drum and shaft. Plus it has all Alto Red Eagle clutches and Kolene steels. Compare all of these features with any other performance 200-4R transmission on the market.
