Transmission no longer shifts into 3rd or overdrive. With shifter in overdrive and in stopped position once you take your foot off the brake to begin acceleration the torque converter slams to a stop and the engine shuts off. Transmission fluid full at all times, engine warmed up. Repeated stalling, repeated tachometer quits. Repeated engine quits when you place in overdrive from neutral. Must start movement by placing in lower gears 1 2 or 3. this transmission never shifts out of second gear. Put it on code analyzer and got 2 codes that indicated pc solenoid torque converter solenoid issues. Seems like these 2000 Buick have recurring defects and GM won't standby their product. Why on earth would a company that designs cars ever put a battery under a car seat. One spark with hydrogen gas under that seat could kill an infant in a car seat if it exploded.. come on!!!

Shortly after taking delivery of vehicle which had 60 miles on it, I noticed when accelerating from a stop or accelerating when turning the car lost power.I would press the gas and it wouldn't go.took to paul batt Buick & skill Buick many, many times, never found problem.at 30K miles, Buick said I should change fluid & check the pan fluid, which showed nothing.problem still occurs.this could be a hazard if vehicle behind me thinks I'm moving and car slows to a near stop w/O brake lights going on. I have 55K miles on it now & problem still occurs.neither Buick or the dealer has attempted to resolve this problem.skill Buick and paul batt Buick were less than helpful.

Service engine light came on. Dealer said code was an 0741 and 0743 showing electrical or possible tourque converter. Dealer said they were unable to duplicate. However it shuddered upon hard acceleration during merges onto freeway or turnpike ramps. The original estimate was about $3000. The garage finally had to take apart the transaxle to for a diagnostic.

The speedometer randomly changes or converts from miles per hour to kilometers, still experiencing problems after serviced.
