POWER TRAIN - AUTOMATIC TRANSMISSION
07/19/2005200923006/14/2004
 Issue with transmission upshift from 1 to 2 gear, 2004 oldsmobile bravada awd the transmission has issues when it shifts gears and causes my family to get thrown back into our seats causing whiplash. it also drastically reduces the rpm, losing speed. this scares us considering that other vehicles might rear end my car. unfortunately the gm dealership holds our vehicle for maybe 2 days and drives it for a short distance. since they cannot find the issue as it is random even though this condition as described in their service bulletin says that it is random, the vehicle is returned since gm will not pay them. they want the condition t worsen before they fix it, putting us is harms way. i would suspect this hapens with the trailblazer and gmc envoy as well.
