[jeffallan574]

alright so i heard that this was possible but i am new and have no idea how to go about doin this so any help or suggestions would be awesome i will reply to questions asked. Right now i have an auto trans with one T-case and i want to put a T-case from a yota with a manual transmission in my 85' 4runner

You have to have 2 gear drive cases, the origonal case is delited.
Depending on which adapter, or transmission you got there is ome problems with fluid starvation on steep hills.

My buddie runs the inchworm adapter, with duals and man tat thing will crawl.

[jeffallan574 [OP]]

will the t-case from the manual transmission work for this?
and is there anything else i would need to do other than throw an adapter on my old t-case and put the other gear drive case on? i pretty much am in the dark about how to do this i just know i wanna do it

You are gonna need the geardrive case from behind that manual tranny. If you are gonna run duals both tcase have to be top shift.

You have to have a particuar auto, I think its the A340H. You could also start with a 2wd tranny (less work).

I may be wrong, but I think you have the wrong auto to do dual cases behind. If you are going duals Marlin or Inchworm are the best around.

i just read the marlin information and they said i can do it with my tranny if your interested in it at all they explain everything really good on the site http://www.marlincrawler.com/htm/transfercase/pickup_dual.htm
thanks for the recommendation of the marlin i think i am going to go with that

I think i already replied to this but maybe i didn't you need to make sure the t-case is divorced i've seen 85's with this and i don't think you need anything but a doubler. Mines out of a 95 t 100 so all i needed
was a 3.0 adapter and it doesn't leak off the tranny is sealed off from t-case. but if it's not divorced it will bleed off can't climb any steep

[jeffallan574 [OP]]

my transfer case is a Aisin Seiki RF1A two-speed is there any where i can look up or can any one tell me if that is divorced? it sounds like this is gonna be pretty easy and not to expensive if i have the right t-cases

You just need too get under it and see if it will unbolt. But if it looks like a big cylinder it probably won't
or call marlins and if he's in somebody can probably run in the back and ask the tranny tou have is rare
so not too many people know whats up with it i've i only seen one and marlin wanted to get it if he ever wanted to get rid of it.


I love mine with only a 4-7 in it climbes killer thinking of duels but want to see how they stop it in low mine spins rear tires
in dirt with break on.
