The synros on my passat were totally fudged... then i put in castrol fully synth .. available from halfords, its about £12.00 per 1L but works wonders, i did run ATF in the manual box, which is silky smooth, but it worried me due to the bearing issues the passat boxes have, so i used this castrol and its as good as perfect, and i honnestly couldnt get it into 1st unless i stopped and double de-clutched, even then it was hard, Now its almost as new, accept when very very cold, then its notchey. So i honnestly belive in your box it will put an end to your issues for many thousands of miles.
