SMG 'clunk'

sjb · 15-01-2013, 06:23 PM

Hi. I forgot to add to my other post that when I test drove the CSL there was a slight clunk from the diff(?) on the upshift. Now I have a manual M3 so don't know the in's and out's of the smg. Silly question coming..... Do you have to lift off when shifting up or keep it planted? The seller said to lift a little for a sit second and this made it smooth. The shift was set to half way between soft and ferocious! Just checking there's not an issue with the diff....
Cheers.

Bit of a clunk is fine,don't start lifting,it as it can cause the clutch to start slurring.

Basically when driven hard with no lift off, it feels like the diff is going to wrench itself out if the car. So sounds normal.

It's not smooth, but it's all part of the drama

dont lift my friend or the clutch will slur and the gear change will stink,

keep your foot in it and allways drive it in manual with the gear change in one of the top 2 setting.
