'98 Jimmy, 4.3, 61K miles, auto trans. Tonite when shifting into
4-hi, the truck sort of "slid into gear" when I stepped on the gas. After that, the truck didn't want to shift out of 1st. Same with 4-lo. The truck moves in and out of all modes with no problems, and there's no service lights lit, no blinking switch lights, etc. 2-hi works perfectly.Any ideas?
Thanks Mike
