Dear Me! Got the P0705 Blues on my 2001 x5 4.4 M62tu with a A5S440Z (5 speed) transmission. Phew, got all that out of the way, now to my problem. Drove the car with a coolant leak. Shortly after, transmission failsafe pops up on display. Code P0705. Confident its not a charging system or battery problem. Thoughts are leaning towards the coolant has migrated into the Park/Neutral Position Switch. Anyone have any input/output electrical values that I can use for diagnosing this switch? I have read of the switch being notoriously faulty. If I find any interruption of electrical signal through the switch, I will open this puppy up to give a look/see. Any thoughts, words from the wise, or from someone who has experienced this switch. Think I should be looking else where in the circuit other than this switch?
