Thanks Mike,  I might take the switch off the other g=E2=80=99box first =
and try it.  However, given that the switch has a steel ball on the end =
which engages onto the brass shift fork, I suspect it is the brass that =
wears.  So unless the replacement switches are a smidgen longer, I =
don=E2=80=99t see how that would change things.  Anyhow, I know what the =
problem is, so when I have it apart I will figure out a solution.

Thanks,  Mirek

Hi Mirek, normally there are thin fiber washers under the switch which =
are used for adjustment.=20

Most are fitted with 1 washer but occasionally you will find 2.

Removing a washer will effectively move the switch further into the =
gearbox which should resolve your issue.

If there are no washers it's probably best to buy a replacement switch. =
The switches available from the usual suspects seem to be quite =
reliable.

Hi listers, I am finding that my BT7 (i.e. sideshifter) is dropping out =
of overdrive if I wiggle the shift lever to the left.  This is without =
doubt opening the contact in the gearbox switch that only permits the =
O/D to operate in 3rd and 4th thus causing the O/D to disengage.  =
Pushing the lever to the right re-engages it. I do not recall any =
adjustment on the switch to screw it in further, in fact I think it is a =
pipe thread and will only go in so far.  I am not sure what part of the =
shift lever actually bears on the end of the switch to engage it.  The =
workshop manual is not much help in figuring it out.  Is it the switch =
or is it what ever it bears on when in 3rd or 4th?   I have not had the =
g=E2=80=99box cover off to look at it yet but thought I=E2=80=99d ask =
the list if anyone had encountered this. =20

=20

Thoughts and ideas?
