Regearing transmission 5th gear?

[spookybathtub]

Thanks for everyone's input. I guess a 6 speed transmission swap would be better, to keep the powerful 5th gear, and then have 6th when cruising on flat highway. I think I could get a used 6-speed for under $200. I could do a lot of the work myself, but I think I'd need a little expert help. If that sounds appealing to anyone in SoCal, let me know.

You would be cruising at about 3500rpm at 62mph with a 6 speed, so you won't get what you wanted to achieve.

The echo has the longest final gear, I wonder if you could swap that in. That would bring you down to 2500rpm at 62mph. But let's not forget the Yaris is a heavier car, and doing this is still counter productive I think.

That's unlikely, as the C160 is much harder to find, will be more expensive, has a much more aggressive final drive (4.5 to the Yaris' 3.7) and requires notching the frame rails on the driver's side. The C60 is more common, but is too wide to fit between the frame rails. If you've got access to a used one in good shape for $200, more power to you!
