I have a 2003 Saturn Vue 2.2 L engine 4cyl. The vehicle will not move when it is in gear. I hooked it up to a ODD scanner, and it said it was the transmission speed sensor and was low on transmission fluid. I've replaced the speed sensor and filled it up with transmission fluid. The vehicle still will not move when it is in gear. Any suggestions?

have the same problem?

What are the exact code number's you have in the computer?There isn't a code that tells you the transmission is low on fluid.

Thanks for the answer. This is Ben's mom. I am checking this web site for possible answers. Ben is in the U.S. Air Force in Anchorage, AK. That is where the Saturn Vue is. He currently does not have time to tow it back to the base car shop to get the exact code. He said it was the speed sensor and low pressure transmission fluid. He is very upset about this vehicle. With temperatures getting as low as windchill -30 degrees, a vehicle is a necessity and this Saturn has let him down. He still owes 5,000 dollars on it, and is making payments on a vehicle he was told could not be fixed. Is there any hope of fixing this vehicle? When he purchase this vehicle from an on base lot, it had a new transmission in it. Can this vehicle be fixed, or is it junk yard material?

Having the code's would really help to figure out the proper repair. If it has a speed sensor code it could need speed sensor's I have replaced speed sensor's on those transmission's before. But if it has low transmission fluid pressure then it could have a bad valve body or bad transmission pump I have seen both but have seen more bad valve body's then pump's.I would need to know the reading's and how they performed the pressure test. Also the exact code's they have. Problem is if it has low transmission fluid pressure then the side cover could be damaged. The side cover is the input and output shaft's with the belt going between them plus the side cover that hold's it all together. It's fixable but it will cost a lot of money just in part's not including labor to repair it. Without all the detail's I can't tell what exactly the repair will be. Those transmission's in that vue is a piece of junk I have replaced repaired and rebuilt a lot them. Never liked them I remember the first time I saw and drove one of the vue's with that transmission when I went to saturn training for it. While I was in school for I thought to myself this transmission is not going to be good.

Saturntech9, just contacted my son in Anchorage. He does not have the original codes because he has used it since on a friends vehicle. He does have the latest one after he replace the speed sensor and transmission fluid. When he hooked it up, the new code that came up was P0720. This was on the memory of the ODD. Does he need to put it back on the Saturn again, or can you figure out what is going on? Any input would be appreciated. Ben's mom.

Ben insisted that is the code. When you google in Saturn Vue codes, the P0715 says it is the Input/Turbine Speed Sensor Circuit Malfunction. What I don't understand is how can a speed sensor make the car not go into gear? Ben already replaced a speed sensor, why is it coming up again? I'm really confused.

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.
File in Section: 07 - Transmission/Transaxle

Bulletin No: 04-07-30-001

Issue Date: January, 2004
Subject:
Speedometer Fluctuation (Replace Input/Output Speed Sensor Assembly)

Models Affected:
2002-2004 VUE
2003-2004 ION Vehicles
with VT25E (Vti) Transaxle (RPOs M75, M16)

Attention: Technician

Condition:

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.

Cause:

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.

Correction:

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.

Service Procedure:

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
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
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.

Tighten
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.

I talked with Ben. He did not see any gel. He does not know if what he put in the Saturn Vue was both the input and output. I will let you know where he ordered the part and the part number, could you please look at it and see if that is both the input and output sensor, or is it the right part in the first place. Ben ordered the part through Auto Zone. It is called a transmission speed sensor, part #SU1539 for $74.99. If you could please look this up and let me know if that was the correct part or not, I sure would appreciate it. I don't know if this web site would let you call a cell number and you could talk to Ben. Is that allowed? And how could I get it to you without the whole world knowing his number?

We don't talk on the phone on this web site it's strictly thru the internet iam sorry about that. As far as that part goes I looked it up and it's the input and output speed sensor's.I have never used the aftermarket one's I have always used the factory one's so I don't how they work. Also did he torque the new one's in place?It's important that he did.I posted the trouble tree for low input sensor voltage and low output sensor voltage that way he can check the sensor's he installed. Let me know what he find's.

I called Ben and he did not torque it. I told him you have the info he could print out and do it. When he can get to a computer and print it, he will try to torque it. I'll let you know what happens. Thanks

The trouble tree's I posted will lead him to the step if he has to torque the sensor's.I would tell him to wait on the torquing step until he follows the trouble trees.
