I have been having intermittent problems with my 2004 Discovery automatic gearbox. Initially it was the M & S lights flashing and being in limp mode of 3rd gear. Have had LR garage look at it twice - cleared faults which indicated problems with solenoid 2. Now it has stopped flashing the lights but seems change up from first when cold, but will not change down below 3rd once I have gone a couple of miles.
The operation of the gearbox is otherwise really smooth.
The LR garage checked the external wiring looms - nothing found and no change, still a fault indicating on solenoid 2. I have had a discussion with an auto gearbox specialist in Dublin and they suggest that the internal loom or the solenoid should be changed, this can be done readily by dropping the sump. This specialist company is nowhere near me and can't do anything for a couple of weeks.
1. Does changing the solenoid sound like the possible fix?
2. Where can I get the solenoid as a spare part?
3. Should I have a go at it myself (I have an excellent mechanic from work that could help me)
Any advice gratefully received.
PS I see someone else on the forum is asking about whether to get anAuto or Manual 2004. At the moment I wish I had a manual.
