My Olds Intrigue will not idile down after starting it, it will stay at about 1,000 to 2,000 RPM even after shifting it into gear.

Cars not control choke themselves electronically, this is likely the car trying to warm itself up quickly. The jerking will occurs anytime you shift into gear at an RPM over a low idle as the torque converter is being engaged. If the high idle last more than a couple of minutes then you might have an issue.

Sounds like you have a shift control problem, either in the transmission or the ECM controlling it. Check for trouble codes (DTCs) with a good code reader.

Loud noises are not good in an automatic transmission. I suggest you have this looked at professionally before something serious happens and you are stranded.

Thanks for your visit today.

Take the car to Autozone or similar business for a free scan of the engine computer even if the check engine light is not on. The retrieved codes provide clues to the trouble spots. Just shotgunning parts at the problem can get very expensive as you have already discovered. Hope this helps!

your torque converter maybe to blame here. a simple fluid pressure test will tell you that. if the pressure is good, your valve bod might be due for a change.

try to reset the computer if that doesnt work reset the idle speed it may have picked up bad codes

make sure the radiator fluid is topped up.

sounds like somthing is cloged up in the valve body or something in your valve body is broke best solution is take it to transmisson mech

my 1997 volvo stopped going on me today and the sport and winter light is blinking like it is engaged. Can you help?

I have a 99 olds intrigue 3.8l Autozone computer states poor electrical connection or short circuit, or failed vehicle spped sensor or drive gear mechanical fault. speedometer works sometimes and drives great next time it raises rpm and speedometer does not work. Where is the speed sensor or where is the elctrical circuit I can check to see if connections are good.
