Hey all. Bought the 91 a month or so ago. Love the truck. Had a few issues which I am slowly working out. Main one has been the TPS for the E4OD. Still having shifting issues after replacing and trying all types of settings. Truck "hunts" for a gear at 30 to 35 which with the 25% factor for tire size is 37 to 43 give or take. Nothing seems to change it. Just shifts in and out of 4 untill reach higher speeds. Unfortunately its the perfect cruising speed for our little country roads. (deer, kids, dogs). So I am asuming it is just the nature of this truck? Also I have been checking the fuel mileage. It is pretty poor. Got less than 10 last tank. My buddy has the same truck with the 5 speed and an early ATS without the waste gate and he says his gets 15 to 18. His is nearly worn out, smokes like a chimney and he never maintains the truck. Mine never smokes, starts clean and runs like a clock. What gives? Do these E4OD trans suck up that much fuel to operate? What kind of mileage are your auto trucks getting?
