I have a full set of 2002 saturn factory vue repair manual's which should have the same code's as the 2003 vue and there isn't a code p0715 listed. There is a p0716 and a p0717 that are for the speed sensor.I also looked in the two online repair manual's we use on this website and same result's. You may have found it on google but it could have been for a different car that was listed for that vue.I have seen bad speed sensor's cause the vue to not move. So were at a road block here I need you to ask him if he removed the valve body and replaced the input and output speed sensor's as a pair because there wired together and you have to replace them both.I also posted a bulletin that has a gel that builds up and causes speed input signal issues talk with him about that and see if he saw anything like that because that would all have to be cleaned up like the bulletin say's.I have seen that gel in more then one of those transmission's.

Speedometer Fluctuation (Replace Input/Output Speed Sensor Assembly)
2003-2004 ION Vehicles
with VT25E (Vti) Transaxle (RPOs M75, M16)
Some customers may comment on a fluctuating speedometer. This fluctuation may occur at highway speeds and higher engine speeds in which the vehicle exhibits a hesitation condition. The fluctuation may also occur when the vehicle is not moving and the transaxle is in Park or Neutral, or during a vehicle launch from a stopped position.
A conductive foam emulsion may accumulate on the control valve body cover and then drips onto the module leadframe located on the control solenoid valve assembly. This emulsion coating may short the electrical circuitry of the input and output speed sensor signals resulting in an erratic speedometer.
Replace the old input and output speed sensor assembly with a newer design. This newer design incorporates the use of an integrated bi-directional zener diode that protects the speed sensor circuitry from foam-induced voltage spikes or irregularities.
1. Remove the 17 bolts from the control valve body cover.
2. Remove the control valve body cover.
3. Remove the control valve body cover gasket. Discard the gasket.
4. Clean the underside of the valve body cover of any white foam or gel-like substance.
5. Locate the electrical connector for the input and output speed sensor assembly.
6. Slide the grey locking clip in order to unlock the connector from the control valve body assembly.
7. Press the connector tab and remove the connector from the control valve body assembly.
8. Remove the bolt and manual shaft detent assembly from the control valve body assembly.
Important :It may be necessary to move the detent lever in order to gain access and remove the bolt securing the output speed sensor to the transaxle case assembly.
9. Remove the 2 bolts and the input and output speed sensor assembly from the transaxle case assembly. Discard the old speed sensor assembly.
Important :The part number for the NEW input and output speed sensor assembly is molded on both the input and output speed sensors.
10. Install the NEW input and output speed sensor assembly, P/N 24229640, and the 2 bolts on the transaxle case assembly.
Tighten the bolts to 11 N.M (8 ft-lbs).
11. Connect the input and output speed sensor connector to the control solenoid valve assembly.
12. Slide the grey locking clip in order to lock the connector in place.
13. Install the manual shaft detent assembly and bolt on the control valve body assembly.
Tighten the bolt to 11 N.M (8 ft-lbs).
14. Install a NEW control valve body cover gasket, P/N 24220201, on the transaxle case assembly
15. Install the control valve body cover and 17 bolts on the transaxle case assembly.
Bolts to 11 N.M (8 ft-lbs) in the sequence shown.
16. Check the transmission fluid. Refer to Transmission Fluid Checking Procedure in the appropriate Service Manual.
17. Test drive the vehicle. Drive the vehicle for 15-20 miles (24-32 km) at highway speeds in order to achieve normal operating temperatures and ensure adequate transmission fluid circulation. Verify that the speedometer fluctuation concern has been repaired.
