Vannin' Home Forums Chevy How to.... new guy looking for help with trans fluid cooler lines

Hello

I just joined (although I've been visiting the site for awhile).

I recently purchased a 1990 GMC Rally 2500, 5.7 (350) v8.

I'm pretty sure one (the lower one) of the transmission fluid cooler lines is leaking (ruptured). I have found puddles and followed drips down the driveway.

I've been trying to look up parts at auto parts shops and not even finding these lines listed..

My questions are - 1) is this an 'easy' fix? (I have replaced a power steering hose / line before, but I'm not very mechanically inclined - nor do I have a lot of free time at the moment.
2) Are these parts still available at auto parts shops? - am I calling them the right names?

I have to work tomorrow, so I will attempt to take and post some pics after I come back (I'll also introduce myself properly then..).

Thank you for taking the time to read.

they usually have everything you need...

Oh & welcome to the site....

You may end up having to bend up your own. It's just 5/16 or 3/8 steel tubing.

Have you tried a GM dealer?

When I replaced the trans lines on my van (88) there were no direct bolt on lines to be found. I had to get straight lines and bend them myself. Not hard to do with a little hand held pipe bender. You can use the old line as a pattern to bend the new one.

Thank you for the replies.

So today I was talking with a respectable guy (backyard mechanic) and his opinion was that I could cut the lines and use fuel line and clamps..

I can't really do anything until Tuesday in any case as Monday is a holiday here... and I need to buy transmission fluid.

My transmission has MD8 written on it.

If you use any rubber lines make sure there made for Tranny fluid.

And keep the rubber line away from anything sharp. I mean anything. Better off with metal line.

Well...if you go that route, you still need to at least single flare the steel tube where you cut them to keep the rubber hose from sliding off. Even clamped the hose can still slide off.

invest/rent the proper tools to fix these lines correctly.
your trans fluid is the life blood of your transmission.

IF you blow off one of the rubber lines you can burn up the trans by running it dry.This can happen pretty quick.
