got a 87 4runner auto 22RE

trying to take off the transfer and gear case off the trans. i can see and feel only two bolts on the outside. and with the removal of those two bolts, it seems like it wont come apart. i suspect the tranfer has to be unbolted from the tranfer gear case. is the true?

the manual setups are a cinch.

i dont want to unbolt the tranfer if i dont have to

thanks
 
i have got to the point where i am trying to separate the transfer. and again it si stuck.
i did find out, the part i was trying to separate before is non seperatable.

this transfer case is hydrolicly and mechanically controlled. :bang:
 
the 2 seals inbetween the trans and transfer are leaking. causing oil to be pushed from the trans to the transfer, causing the rear output to leak. 2 attempts at replacing the rear seal led me to this conclusion.

after further invetigation, it turns out the entire unit must be completley dismanteled to gain access to the seal.
 
Sounds like fun. I have an auto with a hydraulically shifted transfer behind a 3.0 and when it started making noises I started looking for manuals, rebuild kits, etc. I found nothing. Trans shops would exchange the trans & transfer only as a unit, & no one seems to be remotely interested in rebuilding it or selling parts for it. Advanced Adapters buyers guide treats it as a footnote, saying that they experimented with adapters, but the trans was mostly useless without the transfer case. It is a shame too because once my brother decided that it must be destroyed we discovered that in mid-hillclimb, under full throttle, it has the capacity to shift into low range without incident. Now I like it.
 
Hi Wristy,

In the March 2008 issue of 4 Wheel Drive & Sport Utility Magazine, I believe that there is a photo of the type of transmission that's giving you trouble. (see pg. 82)

From 4 Wheel Drive & Sport Utility Magazine:

"Toyota used just one automatic transmission in its `95-and-earlier pickups and 4Runners. The auto trans was factory-married to a transfer case that was different from all other Toyota cases. Inchworm Gear offers an adapter that allows the auto to bolt up to the geardriven T-case."

well its good to know they are tuff, but are certainly not leak proof

thanks for the info. at least not all hope is lost, i suppose. that truck really needs a manual trans
I dont subscibe to any mag other than 4WD Toyota Owner Magazine: Tacoma/Land Cruiser/4Runner/FJ Cruiser/Tundra/Everything Off-Road Toyota!
 
its for my buddys truck. i think this job has convinced him to swap in a manual. i have a transmission, a R150. but it needs a turbo bell housing to work in his. and i have a extra clutch/brake bracket. i said he can have everything he needs. so im sure hes going to start looking for the bellhousing
 
If it isn't too much trouble I'd like to know where you find it, for common ones I use Troy at Cal-Mini or just call TAP. For some reason our local recyclers are getting stingy about selling a bellhousing without the transmission.
