So today I was driving on the highway today and all of a sudden the "service transmission" light came on. I came to a stop and from acceleration if felt VERY sluggish but fine once it was moving.

It was dark so i couldnt check fluid but i am planning on doing that first thing tomorrow. Where is the fill up for the tranny? i know where the dip stick is.

So initial guess... am I screwed or could this be a valve or software?

it all depends what the fluid looks like....black and burnt, it's toast. but if the fluid is ok, could be a solenoid or software issue.

 

can i tell the condition of the tranny through the fluid or will i just know if it needs a flush?

this is the first auto i have ever had so I dont really know this stuff

 

it's a good start. start the car go through the gears and then check the fluid on the dipstick. if it's black and burnt your toast, if not. take it to a dealer and get the code checked out.

 

thanks... ill give that a shot first thing in the morning

 

fluids look fine. Got the code read and it was a turbine speed sensor... any ideas on cost or if i can do it myself?

 

looks like this goes by the name of transmission speed sensor as well

 

You should be able to do that one yours self.

 

do i need a lift? and or to pull the tranny apart? i havent been able to find a haynes for an s60 so i am in the dark here.

 

The sensor should be mounted in the top of the transmission.

 

ok if i get a chiltons or haynes for an 850 (i know the pep boys has one for the 850) will that be close enough to help me find it?

 

Maybe but not sure.
Look for a sensor looking thing mounted in the top with a plug coming off of it. About 8 to 10 inches back from the PNP switch.

 

thanks tech... i will see what i can find.

 

found it, not too concerned about the replacement... just looking for the part now... major autoparts stores dont seem to have it but if someone (tech... ) would have a way to look up the volvo part number it would be much appreciated!

 

Not exactly which sensor the code refers to.
I list 3 different sensors on the transmission.
1. 9495031= Tachometer sensor
2. 9495008= Vehicle speed sensor
3. 8636440= Combined input and output sensor. (look like a Y from the plug to 2 sensors)

Hopefully this will help some.

Did they tell you the code at all?

 

yeah the code was a turbine speed sensor

 

I meant did they tell you the Number of the code?

 

it was either P0715 or P0716

 

Hopefully I will remember to look at work to convert the code to Volvo code. Then I can tell you which one it should be.

 

wonderful, thanks a ton!
