Guys,

I drove my 97 the other day and when I hit the highway I noticed white smoke pouring out the back of the car. I pulled over popped the hood and noticed that there seemed to be a red fluid shooting out of a pinhole in some metal tubing in front of the exhaust manifold. It was shooting directly onto the hot manifold which caused the white smoke ( this is kind of a blessing ) - I limped it home ( about 3 miles but the tranny starting slipping BAD! ) - I assume this is tranny fluid and the tubing is so the fluid can go to a cooler.

My first automatic so please correct my if IM wrong.

I need to know where to get this part and how to get to it to replace. Any help greatly appreciated. :thankyou:

Pictures to follow..

If it is the finned metal tube, it is the tranny cooler, if it is the line below, IIRC that is the power steering cooler.
You could probably get one from a junkyard, but personally, I would get a 6 row universal tranny cooler for $45 and run that instead. Just bypass the tranny cooler that is there.
I run an additional in-line tranny cooler anyway. These trannies tend to run hot especially in hot weather.

Sounds like the metal return line coming from the radiator and going back to the tranny.

Best thing to do is get a good aftermarket cooler, the tank styles are much better than the tube and fin. Then get two 3/8" x 1/4" mNPT hose barbs and some3/8" hose. Replace the fittings in the tranny with the hose barbs and run hose instead of the steel lines.

The steel lines are very restrictive and probably ready to rust out in other places.

Can't you just run an additional tranny cooler in line with the stock radiator (and have the oil go through both?)

Stock there are two tranny coolers - the first is in the radiator, the secondary aux cooler is a tube that runs along the bottom of the radiator - one for PS (bigger lines) and the other for the ATX. You can add a third cooler behind the tube cooler, but depending on where the leak is at you may want to skip a lot fo the other mess.

Will this work for a 94? My has a leak and I have been thinking about replacing the hard lines. :thankyou:

That's interestering. So there really isn't a dedicated coolorer though..? It just runs a line across the bottom?

But technically speaking if you added a tranny cooler it would make 3 passes.. alright.

don't want to be a bastard. but can someone confirm this is true for the Gen3's? I have never seen a hose going into the radiator (form the tranny), just the single finned line underneath, which I connected my secondary tranny cooler to.

It is a dedicated cooler, but it is just a single pass cooler which is connected to the power steering single pass cooler.

I can attest it goes through both. In the Gen 3 SLO's there is no addtional cooler under the radiator like the SHO's got, the only ATX cooler they have is in the secondary radiator core. The additioanl ATX cooler in the SLO's liek the G3 SHO has started for them in 2000 (arguably Gen IV). The Fluid leaves the tranny, goes to the lower fitting on the radiator (passenger side IIRC, then goes out of tthe upper fitting (about 1/3 rd up the radiator), drops down to the passnger end of the aux cooler, and goes back across to the drivers side where it returns to the tranny. This "last mile" is generally where additional coolers would be plumbed in. Also whenever moving oil in a cooler it is best to run it vertically from bottom to top so that air entrapment in the cooler isn't an option, they will self prime in this manner.

I had to cap all of these lines on my MTX.

This is the exact opposite of how I thought it flowed. I may have my in-line filter runner the wrong direction. :(
