Im really confused ive had 2 differing opinions about my problem. Ok before i had my problem i noticed that it was shifting hard. (i have a e4od) So i changed the tranny filter and fluid. it helped for a while. then one day, it just went all weird on me. i was driving hwy speed it was ok until i let off the gas then it was like it was falling out of gear, grinding and such. one day it completely let go and wouldnt do anything, but if i put it in 4 wheel it would go. i have no idea what to look at or even where to start. Please guide me!!!
TY
