Wonder if anyone has had this happen.....
Just had a rebuilt tranny put into my '03 XC70, rather disappointing since it just turned 50K miles. In the past week of normal commute driving I've had a half dozen instances of a vibration or resonance that is either coming from the drivetrain or suspension, I honestly cant tell. Its not unlike driving on one of those warning strips on the side of the road, only lasts 2 to 3 seconds. Everything else seems fine, no error messages or MIL indications. Its only happened in the 30 to 50 mph range at light throttle, mostly on slight upgrade highway. My tranny mechanic says its most likely the tranny adaptive computer reprogramming since it was "wiped" clean during the rebuild. He says give it a couple of hundred miles.
Is it the tranny or is there some other BIG bill coming my way?
Thanks.
