Title: 2.6 gearbox problem solved!
Post by: Migalot on 02 May 2018, 16:33:28
Had many limp home situations caused by the autobox not wanting to change up, then doing so like a kicked mule and giving me the management light. Always had to stop, turn off and reset before it would all come back to normal. This began to occur practically every journey.

I even went to have the fault codes printed out:
P0730 Incorrect gear ratio, and
P1625 Controller voltage switch signal too low.

Frankly, I got sick of driving the car and began looking at spending shed loads on a new car. One evening in March, I desperately needed to use the car, but it would not start at all. Called the AA and got a superb mechanic. He diagnosed a crank sensor and, ahem, agreed to fit the spare I had (don't tell anyone!).

Bottom line is that the car now starts and drives beautifully and the gearbox behaves perfectly, even in situations previously know to have prompted the management light issue.

Who'd have thunk it? ??? ???

My Omega's a keeper now.  :y :y

Interesting. Although the crank sensor is known to cause apparently unrelated faults, I don't recall it causing gearbox issues. Has the ATf been changed and level checked (known issues) to confirm that it will not cause further grief?

ATF all checked when the diagnostic was done on the box last autumn. Truly amazed that the issue has gone now the crank sensor has been replaced, but not complaining!  ;)

IT has now reached the mileage, 60k, where OOF recommends an ATF change and filter clean/change. :y
