Noisy Echo Gearbox Question

[MARSHM]

Hi . Hope you can help me

Bought a 2001 echo last week 5 speed and it has a gearbox noise when you accelerate and decelarate (170k on the clock)

 A whining and slighty grinding noise

The Clutch is great

The gears engage fantasticly and the car is as sooth as a whistle

Took it to my mechanic and he fees it be a tooth of the main shaft

He thinks that it is more cost effective to buy a second hand box and swap them rather than pull the box down and repair it .

I am changing the oil this week to see what comes out (scared)

but i thought i would ask your opinion on this one.

Thanks for your time.

Before draining the transmission, locate and loosen the fill plug. Make sure that you can replace the transmission oil before proceeding to drain it. I expect that the drain plug will be magnetic so look for filings etc. Best case scenario is that the oil level is low. Worse case scenario is that your mechanic will be fitting another gearbox.

Change the oil, go for a test drive and hope things are better.

This sounds a little like lazy guess work.

I would get a second opinion, without giving that mechanic any indication of what the first said.

It could be bearing related, but hard to tell without a tear down/oil sampling.
