    Default 96 olds 4 speed trans cooler line leak

    I recently replaced the cooler line going to the transmission on my station wagon on the bottom side of the car. I can?t get it to stop leaking from the fitting. I tried Teflon tape and that just made it worse, I was wondering if anyone here might have run into this problem before, and what they did to fix it.

    What I did before was wrap the fitting in a piece of large hose and bed it in epoxy with some clamps. Messy but it worked in a pinch and for a long time. A better way would have probably been to cut off the fitting and support bracket, and just run new hose and clamp it over the metal line really good with fuel line clamps.

    Transmission cooling lines leaking means either low-level of fluid or interrupted flow in the transmission. In both cases, the result is an overheated transmission that may stop functioning if the condition persists. Sometimes, it is difficult to spot the leak at the initial stage.

    Hey, sorry it?s been forever since I made this thread. I could see how the interrupted flow internally in the trans would cause this issue, but how would the low fluid level effect that? Also, is there a way That I can diagnose whether or not there is a fluid flow interruption?

    I dont know where you live (your profile is blank), but depending on where you live, you could always bypass the radiator tranny cooler, and do an external tranny cooler. You would have to live in a warmer climate, like Florida, Texas, Arizona, etc.

    The only way for the tranny to have a clogged anything, is for the tranny filter to be clogged. If you are concerned about that, change the filter.

    I have already replaced the filter and fluid, but, I live in Arkansas, that might work.
