I had an aftermarkit Transmission cooler installed on my 07 ram 2500, but it's not doing it's job. The stock one actually kept my transmission temps down a lot lower. The bad thing was we had to cut out the old one to get the new one in, so I was wondering where I can get the stock Transmission cooler with the associated tubing for a cheap price? I know it won't be cheap but I would like the best deal.
Thanks!

 

Also, just for curiousity sake. There's two coolers that the transmission fluid goes through, I think the first one is a "water cooler" or something like that? Can someone give me some more insight on how that cooler works? Thanks!

 

Transmissions without external coolers usually are cooled through the regular radiator. When an external cooler is installed it usually goes from the radiator to the trans cooler and then back to the transmission. dodgepartsonline.com. Is the one you installed smaller than the original?

 

Ya, it was smaller, but it had bigger "fins" on it, and had bigger tubes transfering the fluid.

 

dodgepartsonline had the cooler for around $100, but tubing im not sure. Did your new cooler go from the trans through the bottom of the radiator, through the cooler and back to the trans or did you run it directly from the trans and back to the trans? You may also look for an aftermarket fan to help air flow to the cooler. If you do not have enough air flowing through the cooler it will not work well enough no matter how large the tubes, and fins are.
