1998 Sebring JX p0740 and p0700
 

I recently got these codes after the check engine light came on. The light will come on for 2 days and go away for one and repeat itself. After the light first came on the car now will shake and shutter when keeping the same speed, such as cruise control, but as soon as I press the accelerator the car will stop. Also, when the car is shaking and shuttering the speedometer will go "loose" and wiggle back and forth +/- 5 mph or so but when the shaking stops it corrects itself and shows the correct speed. The codes seem to suggest something with no RPM drop at lockup. Has anyone else had this problem and know what the fix was? Thanks!

need at least a new toqure converter possible a rebuild as well.
