This custom built transmission pan is used to regulate fluid temperature. It has a heat exchanger built into the bottom of the pan that is hooked into the vehicles coolant system. This system has proven extremely effective when consistency of the vehicle is key.
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. This new deep transmission pan for powerglide transmissions acts as a fluid temperature stabilizer and offers more consistent temperature for more consistent runs. Our testing data shows that the warmup cycle of the engine raised the transmission to within 15 degrees of engine teperature. That is, when exiting the staging lanes with an engine temperature of 165, the observed transmission temperature was 150. Likewise, on the cool down cycle our data showed that the transmission fluid would drop temperature within 10 degrees of the engine. That is, the observed engine temperature at the end of the run was 205 and the transmission was 215. The transmission quickly dropped to within 5 degrees of engine temp and followed the coolant temp all the way to150. The heart of the system is our revolutionary new transmission pan. It has similar dimensions to a standard deep powerglide transmission pan but then we cast in a water passage. This passage allows the water that is being cooled by the radiator to also remove heat from the transmission fluid. 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. To do this you must identify the low pressure and high pressure sides of the cooling system and tap into each. By introducing a pressure differential across the cooling jacket of the pan, water will be caused to flow through it. 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. 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. Careful selection of connection points can make this job fairly painless. Run 2 hoses an -6 or equivalent and you are set.
