Installed my chip today, help please

[hemicross]

I have a 2000 ford excursion 7.3 and I just installed my chip today.

1. i remember corey telling me something about dissconnecting a red box under the dash to get the theft lift to stop blinking but can anyone clarify exactly where it is?

2. i was messing around on the 80hp daily driver tune and first to second gear is awesome, got the tires to bark, but from 2-3 it doesnt want to shift on full throttle, it tries but it keeps jumping? i guess, it will shift as soon as i let go of the pedal, i really dont know how to explain it, it tries to go into third then releases then does it again, probably 2-3 times per second, basically its bucking.

what could be causing this? do i need a new torque converter or does the transmission need to be serviced with some type of band adjustment? if anyone could point me in the right direction i would appreciate it
