Well Rudi I didn't pull the PNP switch apart, I reassembled everything & did the checks you suggested: Does it crank in Park & neutral ...yes it did Did it crank in Drive & reverse...no it didnt. The reversing lights come on in reverse too. So I took it for a test run, all gears seem to be changing sweetly, but about 3-miles out on the ring road upto about 60, the arrow started flashing again! I hadn't tried putting it in cruise control . So I read the codes when I got back and got 1:2:2 Break in Solenoid S1 circuit. So looks like you were right. I will take it to Bristol Transmissions & see what they can do.
