Installation is a lot more difficult on the 88's.
Take pictures before removing the old lines. Every clip, bend, etc.
It really helps when reinstalling the new lines.

One of the tranny cooler lines blew out on the highway. I pulled over once I saw the white smoke trail and saw tranny fluid gushing out of the line right in front of the rear wheel. There was no notice at all, never even leaked a drop before it blew. I do almost all my repair work myself but after looking at the lines, i decided to bring it to a local shop. I ordered up the FS stainless steel lines. Was a little disappointed in the workmanship of the shop but to be honest, it wasn't an easy job. Two techs spent about 5 hours and that was using a lift! I'm sure it could be done at home but you have to decide what your time is worth and how much aggravation you want to put yourself through 
That said, the FS stainless lines are good quality and should outlast the car....------------------

LOL Not what I wanted to hear! Mine were fabbed up from scratch years ago by Bob Steiger. I think he free-lanced the routing entirely.

Yeah, I could see it taking a while to do. I used a combination of coated brake line (see previous post) and rubber tranny lines. Took a couple of hours at home. Not that bad really.

That's a name I haven't heard for a while. Twin Lakes Fieros.
My experiences with him are memorable, and not in a good way.
At all.

Connecting new cooler lines - Can anyone tell me which way fluid flows through the tranny cooler (86 GT)?
Input at the top of the cooler, output at the bottom? I should have taken notes but I thought it would be easy to find on PFF.
In the photos below, "A" goes to the cooler so I just need to know the direction tranny oil flows through the cooler - top to bottom or bottom to top?

It really makes no difference which way you hook them up on the transmission. Keep the loop in the one hose.

I have read that the radiator is cooler on the outlet side than on the inlet side. If this is so then it would make sense to follow the coolant flow pattern with the trans oil lines. I will measure the temps at the radiator top and bottom this week to see if there is a difference, if it is significant. or if this info is inaccurate.
Just for reference, on my Fiero the trans oil leaves the Champion radiator internal trans cooler at about 140*F. This would appear to be safe operation for the 4t65eHD.

Resurrecting an old thread.
Does anyone know what the "loop" is for on the tranny cooler liner near the engine?
I had a shop replace my lines and they eliminated the rubber hose loop.

I'm guessing here, but the trans lines are secured to the frame, while the transmission is attached to the cradle, and then the frame via rubber mounts. The transmission will wiggle around, and a loop in the line would be the best way to prevent stress.
