In the automatic cars the diff can be upgraded to a 4.27:1 ring and pinion.
The factory automatic ratio is 3.77:1.

My car was equipped with a 4.27:1
Where would I be able to get a hold of the factory 3.77:1 ratio?
Can it be purchased seperately from toyota?

Anyone have one avaliable.
I am up for a trade if anyone up for it.
