cool trans oil.
any ideas on which would be better. 2nd trans cooler or electric push fan for current cooler. have 2009 ram 1500 hemi, 545 tran. when towing, would like to keep temp under 180 for tans.
I ended up adding a second trans cooler, which is much bigger. It made a hell of a difference, now the temp barely goes up, and i do some pretty heavy towing. I would say that is your best bet.
