Re: 2004 Yukon XL occasional slow 1-2 shifting

Sorry for not mentioning that it's a 1500. Yes 4l60e. Ive been trying to research a little on my own and keep reading about the stock programming being "adaptive". Could this be part of the problem? Im taking your advise Cline and Im not doing anything before the trip except checking the fluid level. I would really like to figure this out though now that it's on the radar. Is there a good place to start?
