Well remembered Hamish - though I hope the stick doesn't have a 'gator but rather a gaiter.

My TR3a overdrive keeps jumping in and out of over drive when engaged or not engaged - any ideas?

Thanks.

Thanks for all the feedback to my post but problem is hopefully solved.

During my faultfinding the battery went flat and and I replaced it, subsequently the overdrive has started working again - why I don't know, I can only assume that there wasn't enough voltage to work the overdrive unit, although the car was starting just fine - just maybe one of life's mysteries.

Thanks for all your input, but it was the last thing that I would have thought was the problem.

But you said it was jumping in & out of overdrive while driving - the battery would have been on charge then, so voltage level would have been fine. ?

Thanks Bob, that was my assumption too but I went for a drive with a new battery and the overdrive behaved itself, although sometimes slow in engaging overdrive so it could be intermittent which as you would know is the worst fault to find. I can only assume that it is the Solenoid as I don't think that there is a problem with the wiring or the switch as I have checked both.
