well i drove mine home which is like 15 min from my gfs house, got on I-95 and the car made a hard shift cant remember what gear it was shifting into but it was at 3k rpms for about 5 sec then shifted hard, then heard a squeaking sound, didnt know if it was the trans or my belt because im having squeaking issues with my belt at the moment. So idk if that was the trans slipping or what. Never had a transmission that slipped before.
