Newb to the forum with his first dumb question

[grimmjeeper]

OK, so you may have guessed by my username that I'm a Jeep guy.

I'm here because I'm researching buying a new 4runner to use as mostly a daily driver. Driving a built 2 door Wrangler with 35" tires and lockers front and rear does have its limitations every day and I want a moderately off road capable (or better) 4wd SUV that can hold more people and stuff and is not terrible on the road. I had looked at a Grand Cherokee but one look at their forums and it's obvious Chrysler has driven the quality of that into the ground and I'm not dumping my money into that steaming pile of dung, not to mention that the local Jeep dealer hasn't inspired any confidence in the one warranty item I had on my Wrangler. The 4runner is at the top of my list right now given what I'm looking for from a daily driver.

Since I love to tinker with my vehicles, I'll probably end up doing some minor mods to the 4runner I buy. I've been doing a bit of searching on here and on Google but I can't quite find the right set of keywords to find what I'm looking for. I built a gear ratio calculator you may have heard of. It lets me pick the transmission, transfer case, and all that and it spits out all the numbers I want. But I can't for the life of me figure out which transmission and transfer case comes in the latest 4runners. I know it's a 5 speed automatic and I can find the low range gear but it would be better if I can just pick it from my list. I also don't know what differentials are under the 4runner so I am having a hard time finding information about what's available for them as far as upgrades.

I'm sure the information is very obviously posted somewhere but my Google-fu is not working for some reason. Can some helpful person out there point me in the right direction? I appreciate it.

Is this what you're looking for (under Transmission close to the bottom of the page)?

With the 5th Gen 4Runner you don't need a gear ratio calculator. You have two choices:
1. Stock
2. 4:56

That is all. Two choices. Simple right? To make it even more simple you can go up to 285's and still be OK with torque and power. Beyond that many have opted for the 4:56 gears. This is not a Jeep so there is not infinite choices. They don't break very easy either.

I still like to know what is in the truck. I'm not going to build this up like I have my Jeep but I like having lots of information even if it doesn't actually matter.

That's exactly why I'm looking at the 4runner and not the Grand Cherokee.

Glad to hear you can use it. I had one Yota guy send me a ton of information for my calculator years back but I have no idea if I have all of the absolute latest stuff. If there's anything missing that you know of, let me know and I'll be happy to add it.

I've used your gear ratio calculator a lot, thanks.

The transmission is the A750E or A750F. Front diff is the 8" Toyota clamshell in use on 03+ 4Runner, 05+ Taco, and FJC. Rear diff is the updated "8.2" same as 2010+ FJC. For the front, there are tons of gear choices available. For the rear, the only options are Toyota 3.73, 4.56, or Nitro 4.56.

That's what I'm looking for. Thanks. :cheers:

On my calculator, it looks like the "Toyota Tacoma and FJ" transfer case option also matches the 4runner. Would it make sense to change that to "Tacoma, FJ, and 4runner"? If so I can do that when I get home tonight.

There are some differences, but as far as gearing is concerned, they are all the same 1:2.57

It's really easy for me to put multiple entries with the same low range gearing. Most of the NP2xx transfer cases are all basically identical but with different names on different lines. There's no reason I can't do the same with Toyota stuff to make it more user friendly. I just don't have the data to fill out everything at my fingertips.
