I would appreciate your advice and comments regarding additives for gear boxes, please.
My '85 Laser has the original gear box with 247,000 miles on it, and it has never been touched, apart from a couple of oil changes over the years. It is currently filled with quite new 'ATF' fluid, and the gear changes are still quite smooth. However, it is now starting to make a little noise, and my local garage has suggested an additive (such as Molyslip) may help a little. He doesn't think it has yet got to the stage where it needs stripping/rebuilding.

Check out the online video. I tried out that friction test at a show over ten years back (when current engine 2.0 litre was in it's first car) and bought a bottle - then bough a bigger bottle a couple of years later for box & diff & my 4x4. I still haven't managed to blow the 2.0 litre engine up yet with over 160,000 miles on it, about 50% more power going through it and regularly thrashed.
