For the trans I'd just do a pan drop and filter change, flush is asking for trouble. Maybe I should start swapping 3800's for people as a side job, had no idea that was the going rate. Not bad for ~6-8 hours of work.
I'll do that then. Just curious, why would a flush be bad? The tranny is approaching 150k miles.
