I've been having some trans overheating / running warm issues with the Allison in my truck.
So I ordered an aftermarket transmission cooler that bolts to the OEM lines - its a Setrab unit from Ingleside Transmissions in CA. I got it today (one week shipping from CA to NC) - and got it installed.
I got everything buttoned up and went for a quick 15 mile drive and it never went over 175*.
I need to drive it more to see how much it cools it down.
Now for the pics:
