I have just bought a 96 M3 Evo with 76k miles. The gearbox was a bit clunky so I had a new clutch put in (expensive). The change is much better, but is still "notchy". There is a slight soft resistance before each gear engages, not much but enough to prevent fast changes in all the gears. Is this normal with M3 Evo boxes? Am I being paranoid? The new clutch bites quite high so this should not be the problem. Will replacing the existing oil with Redline MTL, Lubromoly or Mobil 1 Synthetic oil help? Or will I need a new box (very expensive). Please email me on [email protected]

If you dont hear any grinding your good, also an aftermarket shifter might help out as well.

if you decide to get a shortshift kit i highly recommend the UUC Motorwerks evo kits with the ballbearing bushings. TurnerMotorsport sells them and their website is www.shortshift.com
depending on how the car was driven prior to your purchasing it, the blocker rings inside the synchros may be worn. if so it will take a slightly longer time for the synchro to spin the two shafts up to the same speed, which could prevent your quick shifting. i'm not saying thats the prob, because 76k miles is not very old for blocker rings (unless of course theyve been used hard), but its a possibility.
