Twin Stick question

[Toy-Cra-Ze]

Im not really familiar with the twin stick thing but how does it work can it go in place of where the original transfer case single stick goes where you shift from 2wd, 4 high, and 4low or do you have to have duals to have a twin stick?

if no one has replied before i get home.... i will school you

Alright thanks.  sorry for the stupid question but im just not sure how it works. i saw yours in your 4runner but still was a litttle confused on how the whole twin stick thing really works.

Thanks

Just imagine that your normal transfer case shifter has the LO and the HI connected to it, as well as the 2wd and 4wd. The twin stick goes over the transfer case or can be a forward shift. all its doing is seperating the LO-HI from the 2wd-4wd

[PhantomD aka Zach]

A toyota gear drive case has two shift rods that are actuated by the shift lever, in stock form you are only allowed to operate one at a time (using an detent inside the t-case)

shown in the bottom right of this picture


a twin stick shifter actuates these shift rods individually, allowing one shifter to control 2WD-4WD and the other to control HIGH-LOW, thus allowing you to have 2WD low. Plus more shifters in addition to the dual cases  8)

you do not need dual cases for the mod, but you do need to remove parts of the transfercase to allow the shift rods to move independently. find install directions online and you will see the work involved.

any reason for having 2wd low?

[krogen223v]

I would use it all the time when moving trailers around the yard mainly cuz I had a square tube driveline that made a lot of noise

[bleakhorizon]

looks like it got answered....

and i use 2wd low all the time, i have a locker in the front and in 2wd low it doesnt engage it. so easier steering.  I of course shift into 4wd when it gets nasty, but im amazed at what you can do just in 2wd sometimes...

and to krogen... thats damn near the only reason i put hubs on my 91 runner lol... so i could use 2wd low while moving trailers and junk

[Toy-Cra-Ze]

So would it be worth spending the money to buy the twin stick and put it in the normal transfer case spot? Or would it just be better to get it if you were going to get duals?

[Nimyad]

it's good no matter what, even if you go duals later you still have your twin sticks

[toyotech]

if you guys done mind, could u just explain duals? reasons for duals? thanks, been much helpful

[Nimyad]

well if you have duals with stock gears you'll be able to go about twice as slow and you can right now. if you have duals with 4.7 in the rear case you'll be able to go almost 5 times slower then you can right now. it's more control for crawling

[Toy-Cra-Ze]

Thanks for all the info now i actually know everything about the twin stick.

There are two types of twin sticks for Toyota.  One is for forward shift, and one is for top shift.  So, if you get one for a forward shift now, and go duals later, then you will need to get the other.  But if you have a top shift now, and get one, then later you will have the right one.  The bases have different bolt patterns.

thanks for pointing that out, didn't really think about that... i have a forward in my truck but a spare top just sitting around that i'll eventually twin stick.

[Toy-Cra-Ze]

Well i have a forward shift in my truck but my Dad has a top shift transmission outside in the yard that he might give me. 

[toyotech]

i was just thinking, cant i just put it in 4wd low and leave the front hubs unlocked giving me 2wd low?

[Nimyad]

Ya but your driveline still spins

[toyotech]

Ya but your driveline still spins

true but u still get 2wd low on the free lol

Putting the t-case or t-cases in 2wd will make it easier to turn if you have an auto locker in the front axle.  That's the main reason why I bought one.  I will be testing it in Moab in a couple of days!!

I thought I would add one more way to attain 2wd low.  I wanted nothing to do with switching to manual hubs, though now I wish I had done twin sticks because it's more elegant than what I did. 

I found that there are two vacuum switches which activate/deactivate the front axle when you shift into/out of 4wd.  This system is called Automatic Differential Disconnect (ADD).  I found which of the switches locks the axle, and wired a switch inline with its power source.  Now I can just flip the switch, disconnecting that vacuum switch, and making it so the front axle stays disconnected when I shift to 4wd, allowing 2wd low.  Yes, the driveline is still turning with this option, but it's not like I'll be driving down the highway in low range, and I spent about $10 to get it done. 

Like another mentioned, I use 2wd low for wrestling around heavy trailers with my little 2.7l tacoma.

[Nimyad]

Add is only for ifs though. Most people here run a solid axle which require a twin stick to get the same effect you're getting.

Just wanted to say I appreciate the Feed back from this topic I had been wondering many of the same questions!

It's actually a good idea.  There are alot of us still running IFS, because we are broke.  Not all IFS has ADD.  The quick way to tell is if the rig originally came with hubs or not.  If they came with hubs, it had the standard diff.  But if it didn't have hubs from the factory, it had the ADD.

[Nimyad]

Also ADD rigs came with a different transmission and transfer case.

[Dirty_D]

Interesting.  The more you know...

I know it's not for everyone.  I just figured there are a lot of people with the same ifs truck with add like mine, and what I did is a decent option for those folks.  I hadn't really read anywhere about this modification, so I posted it it.
