Trans Cooler Question

[markfagus]

Hello guys.

I have an 88 with a 3.0 and auto. It has developed a leak that has progressively worsened. The leak is coming the passenger side fitting where the steel line that is part of the radiator over time has loosened. It does not leak a lot, but it is enough to annoy me and mark its territory.

Is the connection on the passenger side of the radiator the hot or cold return line to the trans?

The radiator itself works perfectly fine. No leaks, no overheating issues at all.
My question is, can I "replace/bypass" the tranny cooler in the radiator itself and install an aftermarket trans cooler and pull the lines from the radiator and route them to the external tranny cooler?

I would rather not replace the radiator unless I absolutely have to. I can get a tranny cooler and install install in less than an hour for $50.


Sorry if my question is a dumb one, I just cant find anything on the web that tells me if an aftermarket tranny cooler works as a replacement to the radiator or in addition to.


Thanks,

Mark

I forget which side is the supply/hot side.
But you sure can replace it with an aftermarket one.
And that's actually better than the one in the radiator.
It will cool better, and if the one in the rad ever starts to leak internally, you would have trans fluid leaking into your coolant (not good).

^^^ ? ? ?
He's talking about the transmission. He doesn't have an over heating/cooling problems, just a trans line leak.

If you are perplexed, I am as well. I swear I didn't respond to this thread and was responding to another "overcooling" thread.

I promise.
