Default Re: why 4.10s

[QUOTE=. Also, before I bought my truck I was looking at the Titan, and in all their brochures, they seemed to make sure they made the point that their 5-speed transmission with a rear differential ratio of 2.94 was the equialvent of a 3.73 rear end with a four speed trans. What does our 4.10s equal out to and what does the 4.30s equal out to when compared to a four speed tranny? Thanks,

--------------------
The final ratios (diff ratio x OD ratios) are as follows: 4.30 diff: 5th 3.13, 6th 2.52. with 4.10 diff: 5th 2.98, 6th 2.41. Very little actual difference in what each would tach at highway speeds.
---------------------
The way that Nissan ratio is expressed above is not worded correctly; if 4th is 1:1 @ 3.73 then to achieve a 2.94 final would mean that 5th is 0.79 approx.
