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.

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?
