Fiddly bottom screw on D type overdrive

[Eagerbeaver]

A recent 350 mile trip to Skegness in my recently revived GT6 was only marred by the failure of the overdrive solenoid. Removing the faulty item was awkward but replacing the bottom screw looked impossible without much dismantling.

I worked out that one way of doing this easily is to bond the bottom screw into the screw hole of the solenoid with silicone adhesive. This was strong enough to hold it whilst I positioned the unit in place but weak enough to break the seal to screw it in the overdrive.

It took 2 minutes to get the screw back in – success!

Hope this helps someone.

I replaced the screws holding my solenoid with a hex headed bolt by pinching two of the bolts that hold on the inspection cover (they are the same thread and simlar length as the solenoid screws). I then undid the bolts holding the overdrive to the mount at the rear and jacked up the gearbox and overdrive as far as it would go and used a 1/4 inch drive socket with an extension bar to position the bolt in place. I used a bit of blue tack in the socket to hold the bolt into the socket which allowed me to offer it up to the lower solenoid mounting hole and get the tread started. Still quite fiddly and the rathchet would only managed a couple of clicks at a time but I managed. I replaced the bolts I'd pinched holding the inspection cover with allen screws, some  metric ones that I had could be "made" to fit as the thread was not much different and the inspection cover is not under any strain.

That's a good idea as next time the screws should be easier to undo. I'd thought of blutac too but didn't think it would be stong enough with just the original screws.

Unbolt the gearbox mount from the gearbox and jack the engine and gearbox up (inside the car). This gives about 2" of clearence enough to get better access to the lower screw.
