So I did a search earlier and found a guy with similar issues and his was low tranny fluid. My tranny fluid is full. When I drive its not jerky or anything but its like the computer is not telling it to shift on the right times. Sometimes it will shift fine other times it runs to 3 grand until it shifts from first to second. its been being weird shifting in into OD as well. I was just driving in a 35 and out of no where it dropped down into 1st. Idk wtf is going on. I do have a Jet Performance Chip, do you think its that thing shitting the bed? its a 97 with 50,000 miles so idk what the issue could be. Please Help i gotta drive it home in a week.
