2001 Dodge Ram. 5.9 liters. Magnum, Laramie. Transmission won't shift speeds 2nd and 3rd.
My transmission only works on 1st. gear, it doesn't want to shift to 2nd and 3rd. normally,
but only when I turn off the truck and turn it on again it shifts as far as 2nd. gear and
when I came to a completely stop with out turn off the truck and than I keep on going, it
doesn't want to shift to 2nd gear any more.. and reverse works fine. please help.!!
