Taller Gears

I am planning on adding a LSD to my Yaris to help in the snow and was wondering if it is possible to buy a taller final drive ratio for the manual tranny ?

the gears from an ECHO transmission may work, but you're better off buying a complete transmission.

PM MORGAN about the issues she had trying to swap transmissions.

1. mounts are different
2. shift linkage is different

etc etc

also keep in mind, the yaris uses an 8 bolt ring gear, and echo is 6bolt ring gear so you'd need to buy an echo LSD if you're gonna use it on echo final gears.

yaris final drive: 3.72:1
echo final drive 3.53:1

Please forgive my resurrection of this thread, but I've been interested in a taller final drive on my 07 HB manual. I remember my 00 Echo manual cruising at much lower RPM's, while my Yaris always seems to be dragging itself along with short, quick ratios.

I also monkey with 1st gen Metros (XFis) and the taller final drive in the XFi is probably the #1 reason they get far better MPG's than the base model. If the echo could be a trans/final drive donor I would be interested in doing it.

Has anyone had any experience with this since this thread was hot?

Thanks,
