No,
this particular installation relies on an external contact by the gear
shift lever itself. Not an internal position of the 3rd/4th shift rod.
The usual Lucas pressure switch is mounted on the side at the very
rearmost part of the extension assembly, not on the top in the more or
less center section... this allows only using O/D in 4th gear.. better
than nothing I guess..
