Careful selection of connection points can make this job fairly painless. For our testing purposes, we tapped into one of the legs of the water pump for high pressure and sent the return water to low pressure found in one of the tanks of the radiator. This 7-3/8 long extension housing can eliminate transmission crossmember modifications when replacing a TH400 or TH2004R transmission with a 4L60 assembly. Remember the pump is the “motivator” of the coolant through the system, so the high pressure area is found just after the impeller of the pump and the low pressure area is found just befor it. Turbo 400 Performance Racing Transmissions by FTI Performance - FTI TH400 Performance Racing Transmissions are built with Unbeatable Performance & Durability. By introducing a pressure differential across the cooling jacket of the pan, water will be caused to flow through it. To do this you must identify the low pressure and high pressure sides of the cooling system and tap into each. The next step is to configure your vehicle so that a small amount of flow is diverted from the radiator and directed through the pan. This passage allows the water that is being cooled by the radiator to also remove heat from the transmission fluid. It has similar dimensions to a standard deep powerglide transmission pan but then add a water passage that runs through the base of the pan. The heart of the system is our revolutionary new transmission pan. The transmission quickly dropped to within 5 degrees of engine temp and followed the coolant temp all the way to150. That is, the observed engine temperature at the end of the run was 205 and the transmission was 215. lbs of input torque, though that can be easily upgraded with aftermarket improvements. This model has a conservative rate of 450 ft. It is highly regarded for its supreme durability. All of our transmissions will utilize the Reid Racing transmission case which maintains. Introduced in 1964, the TH400 is an automatic shift, three-speed, longitudinally positioned transmission. On this Website you will find many performance / heavy duty transmission parts the others dont sell. HHP is proud to present the TH400 transmission for the Gen3 Hemi. It is also known as a 3L80, Turbo 400, or. TH400 Performance Transmissions and Parts from PATC. Likewise, on the cool down cycle our data showed that the transmission fluid would drop temperature within 10 degrees of the engine. This transmission was used in many GM applications including Chevrolet, GMC, Cadillac, Buick, Oldsmobile, and Pontiac. That is, when exiting the staging lanes with an engine temperature of 165, the observed transmission temperature was 150. Our testing data shows that the warmup cycle of the engine raised the transmission to within 15 degrees of engine teperature. This new deep transmission pan for powerglide transmissions acts as a fluid temperature stabilizer and offers more consistent temperature for more consistent runs. By applying what we have learned by our extensive knowledge of cooling systems, we have created a new method of cooling transmission fluid as well as pre heating it to a suitable level before each run.
