I have a potential issue with the gearbox or F1 Pump on my 2005 4200.
I drove the car the other day and all was fine, until the gearbox red warning light came on briefly and then went out again. I continued driving the car and parked it in a supermarket carpark for an hour. When I returned to the car and disarmed the alarm I could not hear the F1 pump priming and of course the car would not turn over. I tried switching the battery isolator off for a few minutes to reset the system, but that didn't work.
I decided to leave the car overnight in the carpark with the battery isolator switch in the off position. The car started without issue in the morning and I drove it home. I haven't driven it for a few days now, so not sure if the problem still remains.
Sounds like an intermittent problem. Does anyone have any suggestions? Is it worthwhile replacing the relay unit before looking at the bigger job of the F1 pump??
