Flat driveway here still shudders. I noticed the trans temperature making a difference as well. Another user had success with flushing transfer case fluid and switch to royal purple atf
Just interested to know, how many owners with the 1-2 shifting issue have the car parked on a slope or have slope in their driveway?
I had the issue when I lived up north with a steep driveway around 30 Deg slope with a level garage at the top. The shift change from 1-2 would only be smooth at or above 45 Deg C or 113. F.
Having moved to a flat level area, its all as smooth as silk even on very cold mornings where the OAT is around 0 Deg C..
