Since first adding the stinky stuff it seemed like I could vaguely smell it after driving a few miles and then stopping. Trans temp gauge would typically be in the 150-160 range.
Yesterday I pulled a trailer weighing approx 9,000# for about forty miles at 55 mph, several miles of it being up a 6% grade. The truck ran fine, trans stayed in fourth, TC stayed locked, trans temp went up to 190 (probe in side of Mag-Hytec pan). I could smell the fluid while driving, and when I stopped the smell was very strong. It's not a "burned" fluid smell, just a horrible odor!
Prior to changing the fluid I never smelled anything, and pulled some loads long distances, up steep grades. Whatever came in the transmission sure didn't smell like the "fresh" stuff I have in it now!
Any thoughts?
