Lord Sorbington Posted March 15, 2008 Share Posted March 15, 2008 I've had a quick look at this - my overdrive (J type) doesn't always engage / disengage and has sometimes cut in and out whilst driving.You may recall that the gearknob switch on my car has been disconnected - the overdrive is operated by another switch on the console.I found that the switch had a broken contact so replaced it with a Halfords item to eliminate it as the cause. No difference unfortunately. A green and a yellow wire are connected to this switch. Is this right? How would they have been connected to the gearknob switch? There are the remains of two black wires on the gearlever. Link to comment Share on other sites More sharing options...
AlanChatterton Posted March 15, 2008 Share Posted March 15, 2008 Sorbs,Ther is a hole in the side of the gearlever, about halfway up which the wires go into, then pop out under the switch ontop.Wiring wise................Reversing light switch (side of the box) has 2 green wires going to it. One is the ffed to the reversing lights, one is an ignitioned live. Piggy backed of the live goes to the 3/4 isolator (top of the box) from this up the gearlever to the switch. From the switch to the O/d solenoid then to earth.To be safe, I would rewire the whole thing.If you want, being as I have done this many times before, I can do this for you, and I might even be pesuaded to give you a proper switch!!Have to be after Easter though................

Lord Sorbington Posted March 15, 2008 Author Share Posted March 15, 2008 Thanks Alan, I'll arrange something for after Easter. The gearknob switch is still there but whether it works or not is anyone's guess. I've just not had time to investigate lately........ Link to comment Share on other sites More sharing options...
AlanChatterton Posted March 15, 2008 Share Posted March 15, 2008 No probs, we'll get together after easter and we'll rewire the whole thing, easiest way really. Link to comment Share on other sites More sharing options...
Lord Sorbington Posted March 15, 2008 Author Share Posted March 15, 2008 I hoped I'd got it with the broken switch contact but I'm never that lucky! Link to comment Share on other sites More sharing options...
2500 Stiffler Posted March 15, 2008 Share Posted March 15, 2008 This (amongst other things) is what happened to my Dad's 2500S in the early 80s - caused him to sell it as he was bored of the local garage sucking their teeth and giving the verdict of "it'll be expensive guv..."So I bought an auto!
