    Hey, I had to bring my 7 1/2 foot Meyers Diamond plow in for yearly maintenance. The truck is a 2007 GMC 2500HD Crew Cab Classic with the 6.0 gas engine. The shop is 30 miles from my house and I was going about 55 MPH. My Transmission Temp Gauge was running at about 190 to 200 degrees is this nornal or something to worry about??

    Its a little high. Thats what mine runs towing my 5th wheel camper. I dont think you damaged anything but try and keep and eye on your temps on highway. I try and angle or lower plow to increase windflow. What was your engine temp running at?

    Mine always runs high in warm weather with plow on. My older Dodge not so much but my Chevy always does.

    Chevrolet says 180-220 degrees F is considered normal operating temp on that trans, but as we all know - the lower the better on trans temp. I wouldn't worry.

    Been running Chevys for plowing for 8 years now, trans temp always run about 200 degree's. In the summer if you had the plow on it will be higher. My rule of thumb is to never let the trans temp go over 210. If it does change the trans fluid and filter. I also change the trans fluid and filter every year with amsoils trans fluid and a wix filter. If you have never changed the fluid now would be a good time to do it.

    Just remember the factory gauges aren't always dead on correct. I wouldn't worry too much. When I had a 2500HD regular cab it would push about 200 with the plow on traveling. Never worried about it and it never gave me problems.

    Optimal trans temp is usually ambient outside temp plus 100*.

    That may work in the summer but I have never had a plow truck run a trans temp with a plus 100 degrees. If it was 20 outside the trans temp should be 120 degrees, heck mine runs that year round without a plow.
