Why not just get the XB tranny?

if it's worth it to you to have shorter gears, then it's worth it

the actual transmission case will not fit without modification (from the xA or xB) in the yaris (confirmed by Morgan)

however, you could purchase a used xA/xB transmission from car-part.com or a local junkyard for less than $200 and disassemble it yourself, you'd only need to buy wear-parts from toyota.

be careful that you don't purchase a transmission from an older ECHO, as they have a 6bolt ring gear, and the scions have an 8bolt ring gear.

i personally HATED the short gearing in the scion. 4300rpm at 80mph was annoying, and did not yield very good mileage. the ECHO transmission i had in the xA was awesome, and my mileage improved almost 10%. the only time i missed the shorter gears was on very tight autocross courses.
