you guys are so stubborn. What is wrong with the thing running like factory? If its not overheating and the temp runs stable then why dick with it???? This isnt a gasser, stop treating it like one; it doesnt run better the colder you make it. Mike has said countless times DONT DO THIS.
your trans will NEVER heat up, you'll never get lockup, and you'll waste a shit ton of fuel, not to mention be annoying to drive.
If the original poster is enough of a know-it-all that thinks he can run it against what all of the allison experts have said/advised, then he should be able to look up/source is own damn radiator without help from us.
