Trans Cooler

Hey all,

Found a nice looking Mopar trans cooler out in my scrap yard and was wondering if itís still in good shape.

Also saw another what I think is a trans cooler but iv never seen them this big before so maybe Iím wrong about what it is.

Thoughts on this mopar





Is this a trans cooler as well?

The first one as long as flushed and not leaking should be good the 2nd is ac condenser and not a trans cooler.

Right on thanks, at first I was worried the trans cooler was going to be bent 3/4 of the way down but I just recovered it and everything looked good



Not bad for 11$ lol Iíll have to get the lines another time. When I pulled it, the trans fluid poured out and there were no signs of leaking, so I think itíll be ok.

Uh, that's not worth risking installing it from a junk yard. It's also at least 20 years old. There are better options today. B&M brand has a bypass orifice built in for cold weather. I've got my transmission cooler bypassed with a large dedicated cooler and a smaller cooler for the power steering.

I would backflush it before use (IIRC the fluid flows bottom up. Someone should be able to verify). Some brake cleaner and if you have access to a compressor a shot of pressurized air just in case there is any debris inside it.

BTW thanks for that shifter trip. Looks SO much better than the old (and now incorrect) 249 trim.

Right on maybe Iíll use this for the meantime till I can upgrade to something like Polka has.

Iím glad that worked out for ya. I saw 2-3 more out there again today and almost picked them up for future 242 people. Itís probably the best way for me to contribute to the forum for putting up with my stupid questions lol

I may just have to take me a long weekend and go up there. I could stand to replace a number of broken items (trans shifter mount, seats, center console, possibly sunroof slides).

Polka, do you think it would be too risky even after a good flush, if it has good flow? I mean worst case Iím out $11 and 15min

For $50ish you can get a big 11 x 11" on amazon. I'd keep the Mopar one and use it for my power steering

Just put an inline filter after it if youíre scared it has some contaminants in it.

Does power steering need a cooler? Seems like a couple of you have mentioned that, but I havenít ever read/seen people run the power steering fluid through a cooler.

If you have oversized tires and youíre doing a lot of crawling then it is definitely useful to keep your pump from burning up. For a pavement pounder or light off-roading with 33s or smaller, probably not an issue.
