add the option to create 8 gear transmissions in LFS editor

+1... and why not even more.

Yes, why not even more. Some modern cars and suvs have 10 speed automatics. Also can be used on bus and truck mods. I hope this suggestion be approved.

10 speed for the SCAMA please

Also, allowing ratios higher than 7.500:1 would be cool. like 12.5000

CVT speed could also do the trick.
