4L80E cooling lines

[DP]

On a '93 truck which line is to the cooler and which line is return from the cooler?

Thanks, Dave.

DP - probably no help, but on the '96, the output from the tranny goes into the Radiator first, then to the cooler, then back. Where they actually are at the transmission ( which I bet is what you're looking for) Can't help. Doesn't keep me from chimin' in tho', huh smile.gif

Output from the trans goes to the top of the radiator first.

Thanks.
I want to hook up a temp sender in the line from the gbox to the cooler. I've had a boost gauge, temp gauge, and a piller pod for two years, now that I think I've got a boost problem, I'll finally get them installed.
