Not clear as to what the issue actually is. A bit hard to figure out with the info so far. Is the movement of the shift mech getting stiff when hot or is it just not selecting the gears. Are some gears more difficult than others? Is the clutch not releasing fully? What clutch, master and slave cylinder do you have? Whose rod change mech do you have? Does it have the lockable rotating adjuster? A few pics of the gearchange mech at the gearbox end would help to see what the issues might be.
With a bit more info the actual problem may be more evident. You are not too far away if all else fails. I have been over once before with Martin Gough when you were doing the painting of his red 40 - which is now my car!
Hi Mike, good to hear from you, I remember the painting and it’s nice you’ve got Martin’s car, I’ve tried to contact him a few times but no reply, if you remember a few years back yourself and Martin took my car to Mick at Southern GT and he fitted the rod change amongst other things, the latest box is a new Chris Cole Renault Quaif upgrade, clutch is AP and without digging into my file I can’t this minute give you the details, 3/4” Girling master cylinder, not sure about the slave but if I remember that is 3/4”, to be honest it’s done very little mileage since this box was installed a couple of years back, the car is relatively OK when it’s moving in the upper gears but traffic is a no no with queues behind me as I try to get first gear, it’s certainly worst with this box...any help would be appreciated.
Cheers
John
