he ultimately wants me to send him the tranny..however the warranty doesn't cover the shipping which is a grand both ways to my buddies shop the warranty also doesn't cover fluid and filters, or GM products in the tranny, it does cover $50 per hr of labor though at an authorized dealer, but it doesnt specify if diagnostic time is included..i also don't think just dropping it and looking at it is a solution, as you said mike, something caused this and i think its something electrical...but i am very ready to doubt it's a TCM issue...that's why i have been on here asking individual questions trying to figure out what leads to what...i have looked at all the GM diagnostics sheets and gone through them....i have several EFI logs of the incident happening......i am almost stumped with little left to try, and now that it is leaking fliud i am VERY reluctant to try what i haven't tried yet which is the different NSBU (old one that i replaced thinking it was the cause of another problem), and getting the wheel speed sensor codes totally out of the way
