Auxillary transmission cooler question

So I have a '98 ZJ and I've never bothered to add an aux trans cooler - but I'd like to do so this next week. I'm not a big fan of the traditional aux coolers because they mount in front of the radiator and block air flow. If that's the only/best solution - clearly that is what I'll do. Before I do that though - does anyone run one like this - and if so - where did you mount it?

That cooler is very cool.

The problem is space for it. If you put it underneath, it's in harm's way. If you have removed the stock airbox or AC accumulator, those areas could be possibilities. I thought about doing this many times. The lack of space, additional price and complexity of the install kept me from doing it. But I would like to see it done.

Yep - those were all my thoughts exactly. I thought I'd ask in case someone has found an original/interesting place underneath that was tucked up enough out of the way.

You could probably tuck it up someplace underneath and put a shield on it but you would have to do a bunch of clever trans line routing. The easiest thing to do is to put a large one in front of the condenser. If you think it will hinder cooling, it won't. I have ran mine that way in 110*+ heat in the desert with the A/C running. I bypassed the radiator and it lowered motor temps a little.

You might ask Zjrookie. I recommended that same cooler to him back in April and last I heard he was putting one in.

I think the same thing about the tranny cooler in front of the condenser. I bought the biggest hayden tranny cooler advance had and installed it. It looks like it takes up almost half of the condenser. I dont use the a/c much at all so that isnt an issue but engine cooling is. Never read of anyone saying the transmission cooler caused any overheating or lack of air flow though.

I don't know that I'd try to get too creative with trans cooler location. If the cooler goes it can take the trans with it, so I'd try to leave it where I know it's safe.

Yeah I agree but space is an issue and I want to keep heat as low as possible plus with a skid it will be fine worse case I run the lines back to the rad

It's really not necessary. Mine always stayed cool with a big aux cooler in front of the condenser. Even running the ac at full blast in 110* temps.

I have mine spaced a couple of inches in front of the radiator and have seen no difference at all in engine cooling. The trans, however, runs much cooler.

Same as above post, I got a B&M super cooler and used the brackets to space it in front of the AC condenser, no difference in engine temps. The only other place there is room is underneath the rad, you'd need one of the specialty coolers for hot rods to fit one there, and its more vulnerable to small rocks kicked up, sticks etc unless you have the factory front skid plate.
