Radiator to transmission cooling lines
« on: July 22, 2021, 01:56 AM »
I appreciate all the info! I have been getting all the parts just by following your advice. Thanks!

I made a rookie mistake. When I removed both radiators to get them serviced I did not mark the hoses when I took them out. Dang-it! I don't know which is the transmission return line for either vehicle. I did purchase the service manuals. They explain everything in great detail according to the different transmissions but all I need to know is which is which on my radiators to connect them properly.

There's a picture on the "78-82 Dodge Chassis Service Manual" transmission section 21-26 Figure 8 that tells me "TO COOLER" and "FROM COOLER" but once again I don't know which one is which on the radiators. Any help will be greatly appreciated once more.
Thanks!

It doesn't matter. I go to the transmission oil cooler, then to the radiator and then to the transmission in (from cooler). This way, in the winter your trans fluid will not be over cooled.
