Transmission problem
2001 Dodge Dakota V8 Four Wheel Drive Automatic 75000 miles
----------------------------------------------------------------
Backing out of my garage in the morning I get a pretty good thud when the tranmission engages. It feels as tough there is slack that is being taken up before the transmission engages and moves the vehicle. All u-joints and shafts feel tight. Is there any way to test this through diagnostics, i.e., is there a code saved to the on board computer? If so, how do I read it?

Also, the RPM of the engine seems to flutter at road speed. It seems to happen more before the vehicle has reached full operating temperture and / or closed loop operation. The RPMs will jump 500 - 1000 without warning. I have replaced the cam position sensor with little to no improvement. Again, is there any way to test this through diagnostics, i.e., is there a code saved to the on board computer? If so, how do I read it?

Thanks a lot

Is your check engine light on? If yes turn the key from off to on three times, on the fourth one leave it in the on position, the codes will display on the odometer, write em down and post em...

The check engine light is not on

The TPS(Throttle Possition sensor) May have a bad spot...but not so bad as to store a code...
