Can’t tell if my truck has trans tune or not. It does have some random EFI sotf tunes. Doesn’t go into 6th until about 67mph. Converter locks up real hard in 4th. Unlocks noticeably going to 5th, then locks hard again (can really feel the torque when it locks though lol) Also seems to lug in gears 4-6. Like if I’m cruising in 5th and try to accelerate, it’ll just stay in 5th unless I put the pedal to the floor, then it’ll downshift. Likewise when slowing down from let’s say 5th, it’ll stay in 5th till I get on it again, even if I’ve slowed to like 25mph. Downshifting from 3rd to 1st all seem normal. Should I look into getting a new trans tune or does that seem normal?
