For sale is a brand new in box Derale 20561 automatic transmission cooler that is a direct fit for the Jeep TJ/LJ. It was purchased with a bunch of other parts last year when I was building up my LJ but I didn't install it at the time and I'm selling to put a few bucks towards another project...
Before I install a basic tranny cooler , i just have 1 question.
Will i see lower temps at low speed offroading.
I just can't see it myself.
I really don't want the high dollar unit that you mount under the vehicle with fan.
