Jim, the 1st and 2nd gears are hardened so that the teeth dont break on them as easily. The gearbox on the 951 can be a weak point when power gets high. Powerhaus II sells them if you are interested.

I will also ask Pete to move this to the 951 board where you are likely to get more responses.

I'll copy it to the 951 forum. That way it will be in both places.

I've never heard of anybody having trouble with 1st and 2nd going on the non-S gearboxes. Is this really a problem?

I believe they are only hardened on the turbo S.
