Transmission fluid temperature is one of the things that I monitored continuously with a digital scan gauge. Since we mostly traveled in the Western mountains and always towed, I felt it was an important thing to monitor. Naturally traveling from Florida, I always had quite a few miles of flat and level travel before I got out west. After I switched from Dex III to Transynd I noticed that my normal cruise fluid temperature had dropped about 10 degrees. The transmission also seemed to shift smoother. That was close to 60,000 miles ago and my Allison transmission still shifts like new and my fluid looks like it was put in yesterday. I do change the external spin-on filter every 10,000 miles and top off the fluid. I know that there is probably no need to do this but the filter has a magnet that I always check to see if everything is OK. So far the magnet has always been clean and the cost for an external Allison filter is cheap.
