Re: My transmission temperature gauge hardly moves

Yes on the downshifting. Better engine compression retardation in itself. Helps some. From what I think I have seen in posts here some of the trans/retarder auto trans downshifting might be not working fully with the brake light disconnect on retarder mod.
That mod is a big plus for me as the ability to use the retarder with the cruise control mostly automates the up and down grade use.
As was posted having the retarder come on down grades does help you notice if you are exceeding the speed limits if set at the limit.
I looked at VDO's gauges offered and can only find the zero to 400 degree model.
The VPMS's trans temp display on the computers screen is more helpful as was stated here.
I tend to use the retarder primarily until getting close to 240 degrees then turn if off and start using the service brakes until the trans temps drop 20 degrees or so then start using the retarder again. Alternate.
Rarely do I need to go slow. Wolf creek pass comes to mind where I did reduce my overall speed substantially. Rare.
The coach and toad at 36,000 pounds combined do use the braking systems harder than normal but well within their limits if you have the brakes in their best condition. Weaker brakes make the retarder work harder.
