I've got a trans cooler that I want to install on my '78 K10 with a TH350. I wanted to get a sanity check on the installation since I lost the instructions. I'm assuming that the upper line off the tranny flows towards the radiator while the lower line flows back towards the tranny. Is this correct? Does it matter if the trans fluid goes through the radiator before it goes through the auxilliary cooler? My plan was to run the upper line to the upper fitting on the radiator, lower radiator fitting to the upper auxilliary cooler fitting, lower cooler fitting to the lower tranny line. Does this sound right? Thanks!
