AHA!! Just what I was looking for.. So regarding the 4:56's what about illegal highway speeds?
What I meant by that was that it cruises just fine at 60-70 in 6th and gives really good mpg ( I average 17.5 to 18.9 )
You can get to 6th around 50-60,with the 4.10's ,I hardly ever got to 6th until 70+.
It also does great at higher speeds/rpms,but gas mileage suffers a bit.
When in 6th with the 4.56's ,you CAN accelerate without downshifting.
If you need to accelerate quickly ,just drop to 5th.
If you want to accelerate REALLY quickly,go to 4th
With the 4.10's I had to drop to 4th and even 3rd at times
