heh if they are just pipes there wont be performance ones...

There is probably a gm parts number for them but if you go to autozone they should be able to look at it and tell you what you need. Napa and o'reilleys would be better

mine are rusted and swollen also, on the inlet and outlet right before they screw into the cooler. I was wondering if anyone knew how long they were and if its a PITA to replace them? I was just looking at it yestreday and didnt have time to trace it all the way back to see where the next section joins to the sections attached to the front. Hopeully its not one piece that runs all the way to the tranny? :?:

I think if you look at them from underneath they connect to metal lines near the front wheel suspension.

Trans cooler lines blowing off their outlets at the cooler was the subject of a factory recall back in 1995 (campaign 95-C-68 ). If the high pressure one blows, it can spray the exhaust manifold and catch fire. The fix was to install hose-clamp fittings in place of the swaged (crimp-on) fitting on the high-pressure line. I think there are more details about this recall in the TechInfo section somewhere.

well, thats a nice tidbit of info to know.

I looked at them better today before it went back in the shop and they run directly left for about a foot and a half or so around the radiator and into a rubber elbow before they go down. SO, it doesnt look bad at all. FActory recall? I'l have to check it out and get the Pns...
Thanks...

Keep in mind when they label that "oil cooler", they really mean trans cooler.

Those are GM part numbers. Run them through GM parts direct or AC Delco direct. Best prices.
