Re: 146 1.6l gearbox
How dead is your old box?
I've just replaced my old 1.6 boxer gearbox with a very low mileage one. I got it pretty cheap, and was changing the clutch anyway.
My old box worked 100% ok. All the synchromeshes were fine, and it it had a smooth gear change. It was just getting a little noisy, making a whining noise at certain speeds. After removing it I checked the oil level and it had run low, so flushing it and adding some nice new semi-synthetic oil may well have cured it! as it really wasn't that bad. If I hadn't got another box so cheaply I wouldn't have bothered changing it. My old box had covered just over 88k.
If you have a box with worn synchro's and don't mind a few whining noises you can have it for a small donation. It is complete with all the sensors / plugs etc and the remote unit. The mountings are all good as well.
Let me know if you are interested.
