What happens when you try to start the engine with the box in Neutral and the clutch out?

Really not getting the issue.

Is it stalling because it won't go into gear? Or is it stalling when in neutral and you let out the clutch.

Sounds like failure in the gearbox.

Does it also roll with engine off and box in gear?

because with the engine off, I can select all the gears, and the car starts and runs with the clutch in, I suspect it is something to do with the throw out. Is it common to have a failure with this model at the throw out?

Which engine is it?

Sounds like the fingers from the pressure plate are starting to come off.
You'll need a new clutch.

Well it is gearbox related and you'll see the clutch when the gearbox comes out.
So gearbox or clutch, the box has to come out.

Yup you won't know until removing the gearbox. Then you can properly identify tbe problem.

But whilst its removed you may as well replace the clutch and slave no matter if thats not the issue. Change tbe gearbox oil as you'll need to remove tne half drive shaft abd thats if the gearbox is okay. Generally the petrols dont suffer any gearbox issues. Its very much over engineered the box to the ts or jts power output.

So I suspect clutch will be your issue.

I would drain the gearbox oil into a pan and see if there is any debris in it, if there are bits of metal then worth getting a used gearbox and new clutch to fit. No bits in the oil means its probably clutch failure.

Tomorrow I will do as u say and drain the box looking for metal. Does this also drain the diff i.e. the same oil? I'm looking to confirm that it is or isn't a diff problem. Anyway, if it is the diff would the clanking sound be quicker if I let the clutch out in a higher gear?

No it won't make a difference at all.
I imagine its tne clutch though. Seriously. Ts boxes are pretty sturdy as the gearing and revs allow for an easier time for the drive train.

Its usually a clutch that goes. Even then its more about age of clutch than the friction pad wearing.

Same oil for gearbox & diff, yes.

If it is the diff at fault then the clanking sound should change frequency depending on which gear you let the clutch out in..

I would say its likely to be clutch too, but you never know.

Box is out.
problem is in the box. And as I dont have a manual, does anyone have the workshop manual steps to safely strip and re-assemble the Gearbox?
