Hi everybody,

I hope some of you could help me identifying the problem I have with my 120K 94 Aero.

In the last week she has beggining to make noise when shifting quickly from 2nd to 3rd, but if its made gently the gearbox is smooth as ever has been.

I think it could be a problem with the syncro but I'm not sure.

Thanks in advance for your help, and greetings from Spain.

Hi Suso,

The way you describe the problem definately sounds like the synchro is going on 3rd. Basically you can either drive it carefully with no fast changes, have a box rebuild or replace the box.

Suso,

I suggest you drain, and refill the gearbox with new oil.
This probably won't fix the fault but will remove any bits of metal that may have worn off the synchro, if that is the problem, and new oil may extend the life of the gearbox a bit.

Thanks Harvey,

I'll try changing oil first. Surprisingly I have found that box has stopped making noise, but I still don´t know if it has happened 'cuz I was half asleep this morning when going to work.

I'll be sure this afternoon when coming back home.
