SH-AWD, VSA, & ABS light on with P0847 error code
I have a 2007 Acura RL with 141,000. I was driving entering on the highway and all of a sudden the SH-AWD, VSA, and ABS light came on. I finally had a chance to hook it up to my odb-II scanner and came up with error code P0847. My google of that code says that it is a Transmission fluid pressure sensor. It is odd because about 3 weeks ago I had the dealer do a transmission service on the car. Any idea what this could be? I checked all the fuses, the car still drives fine but only in FWD. Anyone know what this could be?

Obligatory "how old is the battery?" question.

So basically I need to replace the 3rd clutch pressure switch which at 141K sounds like a pretty normal replacement. I have that as part number 28610-RAY-003. I think the 4th clutch pressure switch is 28600-RAY-003. I am gonig to start there and see where it takes me.
Thanks,

I had P0847 come up the other day. I had the 3rd gear solenoid switch replaced. Do we know if it's more common for the 3rd gear switch to need replacing? Do the other ones (I'm assuming there are ones for the other gears) flake out after awhile as well?
