Mk2 Big Saloon : overdrive inhibitor switch

[Rubce]

Hi All

Can any of you please advise on the ease of access to the wiring to the overdrive inhibitor switch? The switch is not wired in on our Saloon and I wish to amend that situation.

Thanks

Hi Bruce, Darren says it is best accessed from underneath as it is situated on the right side of the tunnel  but you could also cut an access hole in the gearbox tunnel if you wish.  Hope this helps 😊

Bruce, jack up the front of the car and place on axle stands.

You may have to take off the exhaust section adjacent to the gearbox, there is a mount that the exhaust hangs off that is attached onto the gearbox, take this off.

Undo the propshaft, swing the prop out of the way.

Place a trolley jack under the rear gearbox mount to support the weight of the g'box, under the 4 nyloc nutsthat hold the gearbox subframe onto the bolts that hang off the through from the bodyshell, take off the rubber O rings and tubes remembering the order they fit.

Undo the soft pad around the gearbox lever, take off the weird panel that fits around the gearlever including the rubber seal. Take of the gearlever, similar clamp to that used on small chassis gearboxes.

Now using the trolley jack to control the drop, lower the gearbox back until you can get your hands up, you may be able to go through from the gearlever aperture in the car. Be careful when dropping the box downwards as you may find the cyl head hits the heater box, place a slim piece of board there to protect the heater box (This is a for mk1 , not so sure about a mk2). Also if an engine fan is fitted, watch that the fan does not cut into the radiator. Just take your time watching everything as you drop the back of the g'box.

You should be able to see the inhibitors, if not use a mirror. J type wiring as you know is very simple, no relay is needed.

Pain in the posterior job as one is on ones back under the car....

No need to cut an access hole.

Bloody hell, that's a lot of work just to gain access! So much easier on a GT6!

Thanks for feedback and suggestions everyone

There is a big grommet in front of gear lever, that also assists access. May need to take console out.

Thanks Colin, I forgot about the big grommet.
