I just did a bit of reading and I "think" what I've found is that the Yaris transmission(C54?) AND the XD transmission(C50?) have the same gear ratios, the only difference is the final drive. The XD has a 3.94 while the Yaris has a 3.72. So in theory the XD gearbox will give you a bit more acceleration.

I'm still unsure if the Yaris Tsport has a 5 or 6 speed though, the Internet has conflicting information...
