Message Alright, first post on tt and first z.

Bought a 91 na with swapped low mileage engine and other goodies about a month ago. It was done professionally, but same transmission and as far as I know same clutch. About 140k on the car taking into account the temperamental odometer (word on how to fix this as well is much appreciated).

Problem: Tached up shifts make me look like an idiot
Tranny grinds going into every gear over about 3500 rpm.
Under that its smooth sailing except for not wanting to go into reverse sometimes.

I've read up on this for about two days now but there aren't quite answers that address every gear. I've added gear oil, castrol, but I don't think redline alone will solve this. I've adjusted the clutch too, but it didn't help. So is bleeding the clutch going to fix this? Or am I looking at a synchro job here?

If it is a synchro job is it recommended to replace them or just get a new transmission?

Point me in the right direction here fellas
