I have a 01 computer running the car, using a LT1 style converter and trans. The car runs and drives fine, shifts at wot and all that stuff.

Went to the track get up for the first pass, do the burnout, then roll up to the line, go WOT and the car feels like the trans slips. It feel loose like this until you shut the car off, restart it and it feels normal again. Did this all day, if I don't do a burnout, it hits hard and just blows the tires off in 1st and 2nd.

I logged the runs, the trans temp never got hot (under 200), the fluid still looks good, even tried adding some more fluid to see if that would help, and no luck. Never got a code for the trans all day.

I've deleted P0502, P0503, P0751 & P0757 since going to the track and it doesn't feel any different after doing a burnout still. I do want to get out one more time this year, and hoping that I can have it fixed of a few things to try/log while there. It was suggested to delete P1870, I haven't tried that yet.

Regardless of anything, fix B1207 being out-of-range.
