Is It Possible For The Apps To Act Up Then Become Ok? At Times Truck Is Fine Then Others I Have To Play W/ The Throttle To Get It To Shift From 1st To 2nd. Say Its Bad For A Couple Days Then It Will Be Fine For A Wk Or So Then Act Up Again? Only Thing I Can Figure Is The Apps. Truck Has 58,000 Miles On It. any Input Is Greatly App. !truck Has Dtt Trans In It I Know Its Not That.
