So my son's 95 850 Turbo with 150K started rough shifting and the other day it started running rough and then stalled. He got started and got it home. I pulled the OBDII codes: P0730(Incorrect Gear Ratio) P0172(Fuel Trim System Rich Bank 1) P0123(Throttle Position Sensor Circuit High Voltage).
My suspicion is that the transmission itself is fine. The fluid,while not cherry red, is red enough and it has no burnt smell. I suspect electrical components.
It will start sometimes but only run for a five seconds if it starts at all now.
Where do I start???? Thanks!
