P38A Select neutral message, stuck in Low.

[Offie]

This happened after I replaced the front drive shafts (after taking hub off) and could it be due to tightening up the drive shaft nuts with gearbox in "Park". I think I have caused something to mis aligne in the transfer box. Maybe the round disc under the blue cover on the transfer box motor????
I took off the transfer box motor and put it manually into high, put the motor into high position (fully clockwise by putting 12+ to yellow wire and -to orange) , remounted motor and took fuse out. Now I drive in high only with no message and indicator noise back, no sport mode either........any ideas as to why it sticks in low with select neutral message?

Maybe the transfer motor has failed ?

I doubt you have the physical strength to damage the transfer box tightening up bolts. Corroded connectors, damaged wiring toasted transfer ECU, Hi/Lo switch operated by the gear lever would be my first port of call.

I agree , At least I now have the car running and I will next check out the ECU and H/L switch as you suggest.........at least these are cheap parts!! Incidently the car has only done 50,000miles from new (1995, P38 4.6) so I know there is no major wear and tear.

Is the gearbox ECU under the drivers seat ? (RHD vehicle).

 

[Grrrrrr]

No. Passenger side on top of the EAS ECU.

I would think it might be the cable adjustment on the gear selector lever. It might not think it is in neutral when you have it in that position. So I would be looking at the gear lever or cable.

Wow. Nice find.
