I always wondered why i crunched going into gears while in lift , it wasnt all the time but 50% of the time, i rang a couple of gearbox guys and they said it was the synchros , and then another guy said it was the way you drive, but tonight was the first time i ever downshifted into high RPM (6500-8000) and it crunched every single time. So i am pretty sure my gearbox synchros are gone, mind you this was downshifting into 2nd, didnt try 3rd or 1st, and to be honest i dont really want to, i dont often drive my car hard. Anyways What would be worth doing to the box? Rebuild, replace? + places to take it to? If so how much would it cost roughly and yeah any other info, thankyou :)
