    I need advice on tranny temp etc, while towing my tt. What temp range should I watch for? Any other gauge spec I should keep an eye on? Trailer is #4400 loaded

    Also changing out the fluid more often is a good idea if you tow regularly

    Towing my 25' TT, loaded at 5400#, my scan gauge trans temp is between, 195*F - 210*f. of coarse that depends on how hard i'm working the truck and if i'm going up steep grades. but typically its the above stated temps. I did a trip from RI to Canada, traveled route 90, a lot of hills, trans temp never reached more than 215*F. I also may add, I have a larger trans cooler on my rig, I removed the skimpy factory and installed a larger capacity cooler. Makes a big difference. Before the installation of the new cooler, my trans temps were reaching 260*F, and that's not good. Add a larger trans cooler, you wont regret it.

    Thanks guys I'll keep a watch on it. Here is what I'm getting driving in town and on highway w/out tt- 122-133 temp. Would that be right? And water temps around 186. Any other gauge I need to keep a watch on? I get 11-12 mpg w/trailer @ 60mph

    For instance, I just towed 3000+ lbs from Ohio to Florida, I was getting 13-14mpg going 67-70 mph. With that weight I drive in D most of the time, but keep a sharp eye on my transmission temp. When i hit grades going through the Appalachian Mtns, the temp tends to start rising and rising at a noticeable rate. Many of the grades are long ones and if I stayed in D, the temp would climb well over 200* I'm sure, so at the base of these grades is where I shift down to 4th, which keeps temp down and steady. Every now and then the temp will keep rising anyway but I've found if this is the case I can feather off the accelerator for a second and that usually stops the TC from thinking too much and the temperature drops back down. Being able to monitor the temp like this is invaluable.
