hey, I have the three bank column of isspro gauges on my truck and the trans temp gauge register starts at 140 and tops out at 320 or 340. The problem that I have is that if it is not above 60 degrees, the trans temp does not move. Should I purchase one that starts at 100 or is that a really big deal?

Does it not even go higher then this if you tow something? I would not worry bout it if it nots even getting to a 140 it not running hot or anything unless you like to watch the guages move. even if it was only running at a 140 not really that warm.

Trans temp is only supposed to be 70 to 100 degrees above the outside tempurature. I wouldn't worry.

Thanks for the useful information, I didn't think that it was a big problem and also, the only thing I really pull is a bass boat on the weekend, so it does not get any higher than about 150.
