Th400 Transmission Cooler Lines Diagram 871 posts · joined 2010. #4 · mar 11, 2013. lower port on cooler. you want the hot fluid to rise to the top of cooler. then return to your trans. 1999 trans am ws6. virginia speed built lsx 418. th 400 & 5600 stall. mwc fab 9, and alot more bs. C3 tech performance th400 transmission cooler line routing 1970 454 kindly help. standard copper radiator fitted; does the top cooler line outlet on the transmission connect to the top of the radiator, and bottom outlet to bottom of radiator, as its not clear from the diagrams i have seen.
Th400 Transmission Cooler Lines Diagram On the transmission (th400) the bottom line is out and the top line is the return. on the radiator the top is in and the bottom out. in other words the bottom transmission line runs to the top of the radiator. the top transmission line runs to the bottom of the radiator. Not so fast, i think the bottom outlet from the transmission (heated fluid) goes to the top fitting on the radiator. just as the heated coolant flows into the top of the radiator. after flowing through the transmission cooler towards the bottom of the radiator (where it is coolest) it returns to the th 400's top fitting (inlet). Correct routing: run the trans bottom pressure line to the bottom fitting of the radiator. the top line exiting the rad should be routed to the bottom line of the external cooler, read it stops (aeration), then route the coolers top return line back to the trans top inlet. basically bottom to bottom and top to top in theory. The turbo 400, also known as the th400, is a popular automatic transmission used in many classic vehicles. to effectively repair or rebuild a turbo 400 transmission, it is essential to know how to read the parts diagram. the turbo 400 transmission parts diagram is a visual representation of the internal components of the transmission.

Cooler feed out i just had my th350 rebuilt and was told the feed goes to the top of the radiator and the return goes to the bottom. the reasoning was the radiator is cooler at the bottom. i made new lines and installed a cooler when i installed the tranny. But make sure it runs thru the radiator first and then the external cooler. you could loosen the lines while the vehicle is idling. if oil flows from the line, youve found the pressure line, if it flows from the radiator, youve found the return line. you'll want to plumb the external cooler into the return line so the atf gets cooled by the.
