Does any other auto tranny Yaris owner regret not getting the MT?

If you want the close ratios of a 6-speed gearbox, then the C160 from a Levin Trueno may be a workable solution, otherwise I'm considering picking up a salvage C60 for measuring and fitment tests.

I meant I wanted a 6th gear installed at the factory, with the R&D and tests behind it, and the warranty.

I don't want to chop up my new car. She's not even 550 miles or one month in my ownership. This isn't some old beater I can just dissect and duct tape back together. This is my only means of transportation.

I would want a 6th gear for highway runs, and higher MPG. Though, I'm sure the engine would be lugging at 60mph in the imaginary 6th gear. I'm guessing 1500RPM. Not enough torque in that little mill.

But a man can dream.
