Rad and Trans cooler

I recently bought what appeared to be a bonestock 92 LS-L. It did have tranny rebuilt 3 years ago and front diff replaced last year. I called the tranny shop that did the work and asked them if they had put in an external cooler they said no. I looked over the car to find the easiest way to add a cooler and found it already has one sandwiched between the condenser and the rad. It does not use the rad cooler at all. Also the rad looks like a very nice aluminum rad hard to discribe but looks more aftermarket to me has the 2 nipples for the trans lines on the bottom of the rad facing the engine, not where I was expecting them which would have been on one side or the other. Those are not connected at this time and there seems to be 3 tranny cooler lines, one on the passengers side and 2 down the drivers.
I am very new to this car, and to subaru's as well could anyone tell me if this sounds right, and why there seems to be 3 cooler lines.

Re: Rad and Trans cooler

I believe I was mistaken about the aftermarket rad.
Looking at a stock rad on this forum I believe mine is the same. Here is mine.

But looking down the sides it looks very nice, maybe its not original?
I know this pic is some what difficult to get a sense of what your looking at but it is the drivers side down the rad, you can see the tranny lines disappearing in front of the rad, behind in this pic.

Re: Rad and Trans cooler

That's a stock radiator.

There is no transmission cooler line on the passenger side.

Some will disagree, but I'd run that external cooler in series with the radiator cooler, especially being in North Dakota.

Good luck with it.

There looked like a transmission cooler line on the passenger side. I agree running the external in series with the rad cooler should have been done. I will be doing that sooner or later, time schedule allowing.

I was mistaken, the line on the passenger side was the Power steering cooler line. Wow I did not know this car had a power steering cooler.
I redid the cooler lines the trans cooler line closest to the engine, should be the one pushing fluid, is going into the ext cooler then out from there into the rad cooler, then back to the trans line. It seems to make a difference with the torque converter locking. Before I would be driving on the highway and the converter would unlock, higher revs, for 2-3 mins then converter locked again for 5-10 mins then repeat.
