I am still having problems with the gate issue going from 4th gear into 5th as the solenoid is not always working to stop me going thru to reverse & the stick getting stuck.
I have unplugged & plugged back in, tried to pinch the terminals in the plug for a tighter fit. Its worked for a while but the problem is back again now. I am now of the thought to cut the plug off & try & get a more permanent connection on the solenoid.
Would Land Rover supply a new plug or would this be part of the wiring loom & not available as a spare part.

Has anyone has done this & managed to get a new plug ?

Thanks for any help/advice.

There was always going to be one!

I have often wondered myself about how the reliability of this seemingly over-complicated solution to overcome what it essentially a badly-designed H pattern.
Other car manufacturers seem to manage by sticking "R" to the left of 1st gear with either a push-down or lift-collar-type mechanism.

I have often felt the solenoid engage as I rest my hand to the right when I come to a stand before reversing back onto my drive.
Good old synchomesh in reverse means it just pops straight in when it's ready without that awful grinding of straight-cut sliding mesh-type reverse boxes.

Sorry for my rather unhelpful two-cents, but I shall be watching this with interest because mine is bound to do it at some point... "We're in danger, we've got to get out."
