Tranny/Trans Case Lube
I too am an AMZOIL Dealer, for my own use only, and when it came time to change the fluid in my 2001 Dually w/6 speed, I contacted AMZOIL's tech department and they told me to use 05W-30 engine oil in the tranny and ATF in the transfer case!
I followed their instructions and then took off for my vacation to Alaska. By the time I got to Anchorage I could barely get the trans into first gear...I had to put in into 3d gear, to stop the gears from turning, then quickly pull it into first gear! Shifting was a little rough too, especially from first to second.
I had the Dodge dealer in Anchorage change out the Amzoil and put in the Dodge factory lube, which the technician referred to as "like mineral oil".
The tranny began to shift better but it is STILL hard to get into 1st gear while standing still with the clutch disengaged.
Has anyone else had this problem with their 6 speed? Have you found a cure?
