    6r80 dyno troubles

    I'm working on a 5.0 6r80e swap tune and I'm having trouble keeping it in the gear i want to dyno in.

    I normally would just tap shift into the gear i want and not have a problem but this is a swap into an old f100 and they did not setup the tap shift.

    So I tried to change the shift map so that it wouldnt shift into 5th and i changed every table to match but it still wants to shift to 5th and 6th.

    There are a few things that make it shift at WOT. Post your tune. If you are worried post the stock swap file. It's the tranny I need to see

    Change the test lock in gear value under trans, it overrides all other shift scheduling.
