Hi all

I have recently had the transmission on my Stag with J-Type overdrive
completely stripped and reassembled by a gearbox specialist after the
discovery of a lot of swarf in the overdrive filter. The nature of the
swarf indicated that there was significant issues within the gearbox /
overdrive unit. This was undertaken when the overdrive stopped working
and it was deemed that the electrical components were working correctly.

While it was discovered that the gearbox did require a new layshaft and
bearings, the rest of the gearbox and overdrive looked fine, so it was
all reassembled and installed back in the car. It was determined that
the swarf was from a previous gearbox rebuild many years ago (by the
same specialists, where the overdrive was not touched).

When I drive the car now, the overdrive is very slow to engage - where
previously it would engage smoothly and almost instantaneously, it now
engages smoothly but anywhere between four and six seconds after
commanding it to do so at the switch. Disengagement is instantaneous.
Another issue, for which it is going back for rework, is that they have
bypassed the inhibitor switch that only allows engagement in 3rd and
4th...

Any clues as to why the engagement is slow? I can them give them
suggestions when I request the electrics be sorted correctly...

Cheers
