i have a ? with my shift into 3rd and when the tc locks up. when the truck shifts into third on a hard accel it will shift and then the tc will lock up normally. but on a gradual accel it will shift into 3rd and the tc will stay unlocked but at around 45ish if u tap the throttle you can feel the tc lock up, and then if its unlocked in 3rd and i have to mat it as soon as i hit the throttle it will lock up immediatly. is it something in the stock programming thats screwy or am im starting to get something screwy inside the box? its been like this ever since ive had it and since my buddy owned it.

I'd say it's a programming issue. my stock TEE4 programming locks the converter @ 38 under light throttle but can't say I've paid much attention to when it does it under hard accel.
