When driving normally, the car seems to skip, like the transmission is trying to change gears. It happened several times while going up a hill and sometimes when driving in normal conditions.

If it's throwing a code, have it scanned. Sounds like the Mass Air Flow Sensor (MAF) or the Throttle positioning sensor, (TPS) Could aslo be a dirty O2 sensor. Scanning will tell.

SOURCE: 1999 buick lasabre hesitation while driving.

there are really only 2 things that cause this problem most of the time i have seen it, 1st a defective Mass Airflow Sensor, the second is low fuel pressure from a failing pump or obstructed fuel filter do u have a check/service engine soon light on at any time? have u had the system tested for trouble code's? Go to any Kragen or Autozone and ask for a OBD 2 trouble code test, it is free, record any code's that show and post them back here on this same thread.

SOURCE: 2003 BUICK REGAL TRANSMISSION PROBLEM.

This is a common problem on some GM cars. There is a pressure control valve in the side cover of the transmission that needs to be replaced. The transmission does not have to be rebuilt. You will need to get a side cover gasket also.

Try unplugging the electrical connection on the transmission to lock it in 3rd. It might get you moving. Although the transmission is going to need rebuilt or replaced.

Losing power going up hills


sounds pretty normal. what speed do you try out the passing gear? anything above 35-45 mph and it will feel like neutral. Passing gear is actually only 1st gear. When you press down the pedal, it forces the transmisson to shift into low gear.

Car looses power up a hill


How slight was the hill and how much weight did you have in your car? When you got power back was it because you were no longer on the hill or were you going downhill?
You may just need to drop down a gear to get the power back, if you have a heavy car even slight hills can cause it to lose power especially if your in top gear. You have a "sports transmission" option (I'm pretty sure it's on all the DSG transmissions) you just need to move it across to the +/- bit and move the stick to the - to go down a gear. Otherwise you'd have to wait until your auto decides it's lost enough revs to go down a gear. Which is why I hate autos.
Otherwise it could be bad fuel or something wrong with the turbo.

Stalls out when braking quickly, worse with going down hill


Assuming that the vehicle is equipped with an automatic transmission, it looks like the torque converter lock-up system doesn't release as fast as it should, so if you brake hard, the converter is still locked up and your wheel brakes stall your engine (just like pressing ******* the brakes with the clutch pedal released on a manual transmission vehicle). Normally, when you brake hard, the lock-up should release and prevent the stall from happening. Might be a bad torque converter, or a bad lock up solenoid in the transmission... Before jumping to anything else, i'd try checking the fluid level in the transmission and an oil/filter change in the transmission. Lots of times one or the other can cure the problem.
