Tranny Shifting Problem

[revrnd]

This thread was closed (due to age) before I could reply. I wonder if in the quoted incident, the driver shifted past M & into 1? I've shifted my '11 from D into M quite a few times & haven't had any overrevving issues.

On the highway he goes "what does this do?" and puts it into "M" and we go from 100km/hr to a nose dive in the highway as it goes into 1st gear... with several thousand pounds of gear in the box and cab of the truck + a quad on the deck ontop of the box..

You should have no issues because tranny should know which gear when going into manual. This guy must have had a error in the software that thought first gear was needed.
