Hi, I hope someone can offer some advice.<p>The gearbox on my M3 has recently got pretty difficult to use. Especially when cold.<p>I also have real problems shifting from 1st to 2nd and also 3rd to 2nd.<p>There is a slight crunching as I try and to avoid it I have to change gear very slowly at lower revs. (Which I know do!) Someone indicated a synchromesh but I am not clear what that means.<p>A BMW garage in Belgium simply said I need a new gearbox which is crazy as the car drives fine when in gear - any advice and help would be much appreciated!

Put some Red Line MTL in there and see if that helps. It did with mine.<p>It used to grind in 1st & 2nd on cold mornings and now it's much, much better.

Can 'Synchros' be replaced if so do you know the approx cost? - any useful web links? TIA!

Syncros can be replaced. It is ness to overhaul the transmission to do so.<p>You might check with Metric Mechanic or Korman they offer exchange transmissions, but sure shipping to Europe would be substantial.<p>WWW.KORMAN.COM<br>www.metricmechanic.com<p>Robert<p><br><i>: : : Hi, I hope someone can offer some advice.<p>: : : The gearbox on my M3 has recently got pretty difficult to use.
