First US 2ZR-FE Yaris swap gains exposure

Yes, if you get the xD gearbox, you need the xD axles. RagNaCat discovered that the differential is the larger one that's similar to the other 1.8L family. Not sure if they're direct swap from a Corolla or Matrix on the axle side, but the Celica and Matrix final drive ring gears go on the xD diff (and not the Yaris/xA/xB).

The speedo sensor hole looks to be the same on all of the C-series gearboxes I've encountered. Looking at the parts diagrams for the xD, the speedo gear is still installed on the differential. If that's the case, you should be able to drop a standard speedo sensor in the hole and keep your Yaris ECU, assuming you have the differential-based speedo in the first place. My 09 has it, and all of the other C-series gearboxes I've torn apart use what appears to be the same part. Looking at the compatibility of the speedo sensor (83181-12020) it's used on lots of stuff: "TOYOTA: 14 models, 905 variants between 1991 and 2013."

The speedo hole was there on the 2012, just capped off, but I don't recall the plastic speedo driven gear being on the diff carrier.

Hmm. I guess it wouldn't serve any purpose, since the bearing seats against the diff carrier itself, but it's still shown in the xD parts diagrams.

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...

The US Yaris has the C50 as well, but uses a different differential carrier. Other than that, the gears themselves should be the same (part numbers and everything). There are some global variants of the Yaris that use a C53 or C54 gearbox, but they should have the same bell housing bolt pattern and mount bosses.

There's a few variants that use the EC67 gearbox, but it's very different from the C50. The slave cylinder is directly on the throwout bearing, and the hydraulic hard lines are different. The case is also 2-piece instead of 3. Here's an eBay UK listing of a similar gearbox.
