Yeah. If you're good with a rebuild long term it's not a huge deal to worry about. Wife's Envoy had the same trans and I toe in OD when it lets me. If it hunts I pull back to 3rd. We got it at 63k so young enough to love it and make it last as long as possible. It had a filter change before I got it and I did a full flush within a week of purchase. We're creeping on the 50k mark since, so another full flush is on the horizon. Keep them clean and keep them cool is your best bet at a long life. Aside from extreme ignorance, you should expect at least 150k from it before really worrying about it. 2007 had most all of the updates they gave the thing.
