last winter my tranny did this thing where when i first drive it when it was real cold out, it wouldnt shift out of first gear for about 10 seconds, it would just keep revving, and then finaly slam into 2nd.... it went away with the warm weather, but since last week it does it to me all the time, and its been like 75 out every day..it doesnt suprise me because ive been beating the hell out of with with my nitrous, and it doesnt bother me because as soon as it dies im swapping it for a tko 3550, but any ideas on what it might be?
