Yes, 4.6 is Kaaz. We can also get the 3,4,5 gears from Kaaz.

The TRD 4.7 is $1350 but is not a direct fit in the Vitz, it's made for the AE111 C-160 transmission. You will need to machine the housing and swap bearings to fit the TRD 4.7 which ends up costing more than getting the 4.6 from Kaaz.

Goodness me,
I didn't see this tricky to install trd 4.7.
Things going interesting.
Sure 4.6 is too long.
Maybe better 3,4,5 shorter to go 180kph at 7000rpm.
Even better + 4.6 finalr 170kph.
Please tell me price for kaaz 3,4,5 gear set + 4.6 final.

From here

they can see trd 41201-AE061 4.7 final gear is bolt on c52,c56 transmission.
Now I know c54 trans on yaris but not sure on vitz too.
I know 4 sure my 2003 vitz old model fits same starlet turbo LSD.
EP82 Starlet turbo fits c52 trans.
Are u so sure my car (old model vitz) cannot go starlet gear set or final?
Are u so sure my gearbox housing easy fit kaaz ones?
Just not funny to buy something expensive they cannot fit

This will not bolt in, it requires machining/clearancing the housing and replacing the carrier bearings.

Yes. The Kaaz 4.6 is made for our Yaris/Vitz/Echo Transmission.

I agree, so why take a chance?

Can help me understand if better kaaz 3rd 4th 5th or 4.6 final?
I mean 4.6 final than 4.3 shortens all gears and allows each gear to put more torque to ground and shift revs same as stock while 3rd 4th 5th shorten these 3 gears and change shift revs.
Then 1st e 2nd no quicker acceleration and 3rd, 4th, 5th probably miss part of torque band.
My top torque stock cams is at 4500rpm.
Kaaz close gear set when I shift to 3rd e 4th I'm at 5000 and
when to 5th I'm at 5500.
So where's gain with kaaz close gear set when I miss power band?
I mean at 5500 torque curve is going down quickly
not growing not standing.
Am I wrong?
