#1 of 4 Confused???Transmission Temperature Gauge Reading by carolinadeb Jan 22, 2009 (8:58 pm)
I recently bought a 2005 2500HD with about 20,000 miles on it. Today, I noticed that the transmission temperature gauge was barely reading anything. This is while driving over an hour at 55 mph in 45 degree weather not towing anything. Is this normal? If not, what could be the problem? Should I be concerned?

Replying to: carolinadeb (Jan 22, 2009 8:58 pm) I assume this is a diesel or an 8 litre with an allison trans...if so yes, they have an excellent cooling system and that is very normal...will run very cool anyway especially at highway speeds where the torque converter is fully locked not allowing much heat to be generated. Most of the heat generated in an automatic trans is from torque converter stalling. Replies to this message: carolinadeb (Jan 24, 2009 3:03 pm) jeff2500hd (Feb 22, 2009 7:36 am)

Replying to: rhtrans (Jan 24, 2009 6:36 am) Actually it is not a diesel. How do I find out if it is an 8 litre with an allison trans? I drove it today in 64 degree weather at varying speeds from 35 to 65 for about two hours and it registered 80. Replies to this message: jeff2500hd (Feb 22, 2009 7:36 am)

Replying to: carolinadeb (Jan 24, 2009 3:03 pm) I have a 2500HD also and it has the 6.0 gas in it. Tro help you out I bought the truck new and from day one it runs cool. Only on a hot day especially pulling my camper it will go upto 180 to 190. During winter months I rarly see it move. Take Care....
