possible transmission and gearbox problem
 

Model is an 1986-87 S4 with an S5 turbo 2 engine.

I havent yet taken the time to look if its a manual or turbo transmission.

Problem:
1. revving the engine above 4k rpms, a cliciking/rattling sound comes from the transmission or gearbox. If I hold the stick shift during this time, the clicking stops or is less.

2. similarly, there is a chafing or metal grinding sound coming from transmission/gearbox area. I cant really pinpoint the source of the sound yet.

I am told that the first problem is due to gearbox which is a little worn out. Are there any other possibilities?

As for the 2nd, I have been told, that its a synchromesh problem. My problem is the sound never occurs when my mechanic is in the car... lol. Car doesnt like me.

Does anyone know what be wrong?

Synchros have nothing to do with rattling or noises.
Synchros going bad makes the transmission hard to shift into gear with the engine running.

Thanx a bunch, will have to source for a gearbox then.

At the moment, I'm working with a new mechanic whom I dont know too well but is supposed to be a rotary specialist and thus far he's done quite a good job fixing my problems.

I just need to know from other sources what possible things to watch out for so I know what's being done.

Is there anything else in the transmission that I should be watching out for?
