1. Turn off your MDS, as long as it is in 8 (or less) MDS will be disabled.
2. To limit excessive shifting - say you are traveling along at about 65 mph and there are constant rolling hills that cause your transmission to downshift and upshift almost constantly between 8th and 7th gears. You would just lockout 8th by pushing the minus button until the 7 appears in the dash - this will limit the top gear to 7th gear and most likely stop most if not all of the constant shifting.
as an example.
2 - is much more common, esp. when loaded or towing.
I went from 3.92 gears in my 14 sport, to 3.21 gears in my 18 sport, man does this 18 hunt for gears alot. But i dont worry about it, my 18 is ALOT smoother shifting than my 14 was. Dont even feel it shift. So, it can hunt gearing all it wants, its doing what its supposed to do. If this ram 8-speed bothers some folks, go drive another brands 10 speed...lol, talk about gear huntin`
mostly easy fix for the MDS around town and no tune required.
also not that i have dynoed the truck but it can hold 6th (1:1 ratio) for dyno pulls, makes it easier and safer.
same as paddle shifters on newer cars but just buttons not paddles. same effect though
Tpony is spot on. Going into tow/haul mode will change the shift program as well. In tow/haul, mine down shifts rather responsively when going down hill. When i use the +/-, i drop into 8th gear, it too, causes mine to down shift sooner when going down hill.
My 1500 engine and everything will turn itself off. Almost instantaneous the engine starts again as does does electrical components. The transmission indicater showed it changed from D to +/-, and a 6. In order to get it out of +/-, puts it into neutral and back into drive and the engine then continue runs again. What is going on?
