I have a '96 DeVille and a service transmission message. The code is a PC0717 and I understand this code to be the input speed sensor. My question is, what is the least expensive way to get this fixed. I know the tranny has to be pulled opened up and reassmbled and reinstalled. I am wonering if anyone has a shop manual to tell me the labor hours involved, so a shop won't rake me for doing this. Any help is appreciated.

'96 Deville same code, No idea. Any luck ? Car is old with 201k. Worth fixing? Not sure :confused:

There are others here more knowledgeable, and hopefully they'll respond too.

I went through this on my 96 Deville 9 months ago, also diagnosed with a bad input speed sensor. My results:

1. Knowledgeable friend says it's a big job, a full day (8 hrs) partially because of the position of the tranny to the engine.

2.I have a reliable local mechanic who had a transmission specialist look at it. The estimate to repair was $400, BUT my mechanic said basically he couldn't guarantee this would work for long. I dunno, maybe he just didn't want to do this labor intensive job. He really suggested it was time for me to get another car (120k miles).

3. The car looks great, so I put in a salvage yard tranny for $1k. Happy ever after.

jtauber, I have a question...why did you decide to put in a salvage yard tranny rather than replace the sensor on your own tranny and put IT back in :hmm: ? Seems to me that you had to expend the labor and bucks to pull out yours anyway, and it would have been just as easy to put yours back in with the new sensor as it was to put in the salvage yard tranny. Just curious. faustd

I know there are 2 speed sensors, i cant remember which one is easy to get to and which one is hard...

If memory serves the turbine sensor is the easy one?

The shop manual does not give hrs. for repair. Just the proceedure.
There are 2 speed sensors.
The VSS (vehicle Speed Sensor) located on the housing above the right output shaft. Easy fix.
The ISS (Input Speed Sensor), I've heard it described as a $20 part located $2000 deep in the transmision.
You are correct, the trans does have to be removed and the side cover opened. No ideas on the cost.

fausted,
good question about why replace vs repair. I'm not mechanically inclined, so my mechanic was selected based on referral and reputation. He was really saying $400 may not a good long term fix. Before I got the salvage tranny I called into the local radio program car guru, and without mentioning the boneyard name, he singled them out in the broadcast as reputable.

The replacement tranny was from a 98 DeVille with 48k miles. My car has been properly maintained and looks just great, so I want to keep it for a long time.

Right or wrong decision? I dunno but I'm pleased with result.

so anyone know wahts involved in replacing the input turbine speed sensor?

Probably looking at 12 hours according to alldata.
You'll need more parts, you have to remove the side cover and channel plate.
An experienced tech could do this in the car, but it's tricky.
Also those who know can remove certain bolts and remove the pump and channel plate as an assembly.
It's a pain I know.
