Hi got a saph 4x4. When i initially bought it, it was only running about 310bhp max and still is.
The gear changes and selections were fine for the first few months. Now slowly over the months its come to a point where i could hardly select 2nd and third gear when am launching and giving it some. Driving normal theres no problem but when you give it some it jst won't want to select gears very easily. You have to wait til the revs come down and bit then it'll engage into gear.
Could it be a box problem or some setting/adjustment on the clutch cable/rachet etc?
Ive got a spare box which i can replace it with but want to make sure if this one is knackerd 1st...
so any help/suggestion welcome
(oh running an alcon 6 paddle clutch btw)
thanks

yup, second/thrid gear syncros gone mate
if you are lucky it will only be the syncro rings, but from the soudn of it the teeth on the cogs may be gone too
the syncro ring slows down the gears so that it will match the rotation speeds of both, but these are made of brass and wear away easier
what you may find is that, after a while you may not even be able to stay in second and thrid as there will be nothing stopping them from popping out, then it's rebuild time, but the better option would be to rebild the box you've got spare and then get that fitted, at leat you know you'll be putting a good box back in again
