I have a 99 Regal GS supercharged
Recently it started running a little sluggish. We had a tune up done with no success. If you start the car and immediately start to drive whether it is forward or reverse the car is hesitant to go. You have to get up to at least 3000rpms, and it barely crawls. However if you let the car warm up for at least a minute there is no problem. We had the car looked at and we were told the transmission needs to be replaced. Is there something else that could solve this problem that is not sooo expensive. I looked forward to any advise.
Check the idle air control as it is operating when you start the car and after the car warms up it is out of the system.

go to the local repair shop...(IE.carx,midas.etc..) and ask one of the mechanics, If they will print off the diagrahm you need, they will do it for a small fee 5-10 bucks or so as long as your nice!

CHECK FUEL PRESSURE IT SHOULD BE 41 - 47 PSI. IF NOT REPLACE FUEL FILTER.IF NO CHANGE. REPLACE FUEL PUMP.IF FUEL PUMP IS GOOD.YOUR PROBLEM COULD BE A INTAKE LEAK OR SPARK IGNITION PROBLEMS.ALSO USE A SCANNER TO CHECK FOR FAULTY SENSORS OR THEFT DETERENT PROBLEMS.

I would change your plugs and wires with original a/c delco factory wires and plugs.My buick did the same and got corrected with factory wires and plugs.I tried most of the after market and they didn't do the job.

the transmission was serviced about a year ago, just a fluid flush though. It was also serviced today by a local transmission business, and they were unable to pinpoint the exact problem.
unfortunatly it does sound like a problem with the hydraulics in the trans. how long ago did the transmission get serviced?
