Re: transmission cooler lines

the only thing the sites say are 67-70 t400 and 71-72 t400, they dont say anything about engine size, i was curious if the lines ran different on the earlier trucks, ill look for a diagram.

Re: transmission cooler lines

Re: transmission cooler lines

it would be alot cheaper and easier in my opinion to just bend your own. mine cost maybe $60 and that includes the tool i bought to bend them.

Re: transmission cooler lines

The radius of the bends coming out of the radiator are different, I don't remember which is which but they both should fit.
