I'm curious as to why stock auto v6s have 4.56 gearing and auto 22res have 4.10s. It seems like it should be the other way around. I mean, wouldn't having 4.56s in an auto-i4 setup yield less stress on the engine? Of course the engineers knew what they were doing, but I don't. Why does the larger engine have a higher gear ratio? For example, stock gearing in a chevy with a 350 is 3.XX,((3.93?)) correct? Yes, the 350 can turn the wheels better, but in theory, shouldn't that be the same for the 3vze compared to the 22re? I'm sure I just don't understand gearing correctly.

This really doesn't matter, I was just thinking about....

 

I believe it is because the transmissions are different. I can look it up if you really want me to.

 

I believe most auto 22re's came with 4.30 gearing.

 

because the 22re has more power

 

i actually had 3.73 gearing and a .69 final OD in my truck before i swapped a 5 speed

...But i have a 22r and it's 2wd

 

im going to say b/c maybe the 4cyl trucks came with smaller tires b/c they were not the "premium" trucks like the ones with v6/auto.

V6/Auto was considered the cats ass back in the day. The new bigger engine and not having to shift with the auto.

I believe the stock size on 4 cyl trucks was 235/75/R15 (~29") and the 6 cyl vehicles got 31-10.50R15s

 

Actually the 2nd gen 4Runners with the 31" tire option and auto tranny, came with 4.88's.
That's what mine has.

It has to do with the auto transmission. The lower gearing makes up for the power loss due to the auto.

 

Not true, unless they changed ratio's mid way thru the 2nd gen. My 2nd gen, '91 V6, auto, 31's, came with with 4.56's. I wish I had 4.88's.

 

alright, even if auto 22res came with 4.30 gearing, its still higher than the auto v6s. What about gear ratios within the tranny? Would that effect it? I didn't consider tire sizes, either. I need to quit posting at 3 am

 

Mine certainly came that way. Maybe they switched midway through the '95 year or maybe it was was in the SR5's or whatever.
At any rate, it's marked on the door sticker and a manual checked confirmed it on mine

Ya, who knows, I've got the SR5 as well. Like I said, mines confirmed 4.56's.....wanna trade??? lol

 

Mines an SR5 3.0/Auto 4:10's (as indicated by the door sticker) and stock tires were 215/75 15 - so really there is no set guideline...
