Questionhappens only in the morning. The car idles fine, switch to Drive or R speedometer doesn't work, won't switch above 1st gear, huge loss of power (it takes 3.5-4.5k rpm to go 20mph). I let the engine worm up then turn it off, clear both codes (every time they show up at the same time : P0500 and P0720), start it up again and... there it goes... runs perfect. Runs perfect for a whole day. Next morning the same story, three mornings in a row!
wiring? sencors? something else?

Answervehicle trouble code P0500 - Vehicle Speed Sensor Malfunction = Transmission Limp Mode.
P0720 Output Speed Sensor Circuit Malfunction = Transmission Limp Mode.
The computer is getting no signal or error signal from the speed sensor.
