Anyone running a data monitor? Curious as to what others are seeing as far as temps during normal driving (not towing)? My Banks gauge is reading 230-235*F for engine oil temp and 180-185*F for transmission oil temp.

Haven't looked at the oil temps but I've noticed the tranny temps are in the 85-95c range even in cooler weather. From what I understand, these trannys are equipped with a thermal valve for the cooler lines so that it won't send the fluid to the cooler until it reaches a certain temp. I know this was a problem on the 6L80E on later years and guys/rebuilders were removing this valve.

Haven't really towed our 6500# RV trailer yet and I will be keeping a close eye on it this summer.
