problems with the s80
 

so as I'm doing about 55 today, all of a sudden the rpm's dropped real low, all the gauges shut off, ABS, Check Engine & BRAKE lights came on, A/C stopped working and a transmission service required message along with brake filure message along with engine serive required message came on. As i pulled into a parking lot the brake pedal was really soft and i had a hard time stopping and then the shifter would only move to the N or D positions but even in D the car barely moved. Sooo, I've had the ABS module rebuild a while back ago and hadn't had any problems but I left the car there and just drove it home with no problems but the tranny message was still there. I pulled these OBD codes from it:
PO722
PO455
P1633
P1631
P1618
So, anyone have any ideas? I'm thinking its time for an '05...
any help would be appriciated,
thanks

RE: problems with the s80
 

Did you shut off and restart the car- then where able to drive it home? Its kinda unclear.

If it drove normally after shut-off/restart.Then it MAY be a control module problem possible communication error. Sorry but I don't know generic codes. So they don't mean anything to me.

Shout back and I'll try to help.
