These are control system issues so they are electrical
P0702 Transmission Control System Electrical
P0705 Transmission Range Sensor Circuit malfunction (PRNDL Input)
Replace the transmission range selector (large switch on side of trans) switch and make sure the connector to it is not corroded, clear the system codes and give it a try.

Check engine light is on. Is it the PO705 vehicle speed sensor A maken it do that?
Yup, if you scanned your engine computer and you got a code P0705, you can bet that's why your Check Engine light is on.

P0705, however, is NOT a Vehicle Speed Sensor code on this vehicle. It is a Digital Transmission Range Sensor code. It is caused by an open or shorted circuit in the TR-1, TR-2, TR-3a or TR-4 circuits. This code CANNOT be set by an incorrectly adjusted TR Sensor.
