Hey all,

I know that this might be a crazy question, but has anyone put anything more than a 6 speed in a diesel truck? Would it be remotely possible to put anything like a 10 speed in?

I know that it would be an insane amount of work to get something like that to fit, but sometimes it would be really nice to have more speeds.

Anyway, its just something I was thinking about, what do you all think?

 

There's a red Chevy Dually on YouTube with a 12V Conversion that has a 10spd in it
I did come across a Peterbilt on E-Bay that had 5.9 12V with a 13spd
