yep, i could add an aux cooler but the work it takes for the small engine to get that chunck of steal to move in deep snow with stock gearing is asking a lot. a doubler would make that truck a force to be respected...

as far as i could tell (and remember) the only difference between the 2 trannies was the length of the output shaft so... i just wanted someone to confirm that i could sut the output to length, what that length needed to be and that there was an adapter i could purchase...or not.
in the end i will be stripping the one LJ78 in Ontario and check if this can be done or not. if so then the auto equiped LJ78 can move up a big notch in it's off road capabilities...

If it's anything like the 90 series that I took apart, the built in tranny cooler could be blocking the flow in the rad very much, that and the high heat coming from the TC slip in difficult terrain could exceed the already marginal cooling capabilitiy.
I can only see benefits from fitting a big separate tranny cooler and getting rid of the stock one in the lower rad tank.

you still should not remove the cooler from the lower rad since you need the engine heat to bring hte tranny fluid up to operating temp...or so i have been told.
i have an aux cooler sitting here and if i get time (and if the units do not sell) then i will give that a try...what do i have to loose but some unwanted heat...right?

On a lot of automatics, oil does not flow through the oil cooler until it reaches a minimum temperature, then it is redirected through the cooler. If that is the case with your transmission, "engine heat" can't be added to the transmission oil by way of the oil cooler in the radiator until it is already hot.
We are currently working on an A440 crawler (MC26 adapter kit). The MC26 would allow the use of any T-case behind a RF1A reduction housing ( 3spd/4spd, split case, RF1A, VF1A and even Dana junk). We just have so many projects in the works that they never get finished. We have started changing this.
BTW off topic does any body know the proper Toyota name for the 3spd, 4spd and Split case? (example: RF1A is the mini truck gear drive case)
Thanks

My Split Case BF1A behing my H55F it's the same alum box that come behind H41 and H42 here in Panamá ( even with diferent gear ratio inside ) but never know the name of the t-case ( that's not a "split case" ) that come behind the 3 speeds ..
I realize this post is 2 years old...but I figured I'd give it a shot. I need that stubby input shaft you have circled in the first post. If you ever did find a source for one could you point me in that direction.
I've bought some r151's from a mine but they were missing the cases. I have a couple split cases but no way to mate them.

I forgot all about this thread. No, I never found the shaft and haven't really pursued it.

I have a complete R151F/splitcase setup to sell as a whole unit if you're interested. It's from a 1987 LJ71 with approx 150,000kms on it

Dave at Japan 4X4 can locate the intermediate shaft for a decent price.

crushers...think I found one in the US. Not bad about $130 new from toyota with the coupler. Dave was my next stop if I didn't find it at Peak.

What are you asking for your tranny/tcase?

thanks for the replies guys. I found what I needed from Peak Mech.
The last piece to my puzzle is the adapters for the b3.3. Supposedly they will be ready soon.

one more question
now that i have the r151 and and split case in front of me...
does the shaft just slid thru the case and into the couple in the tail housing ?
are the gear, bearing and spacer reused in the same configuration as they were behind a 4 or 5spd?

everything is the same for 4 speed and 5 speed...

Well I guess I'm just gonna order the stub shaft and coupler and hope it works. I'm using a split case from behind a h42 that was in a 81 40.
Oh yeah if anyone cares...the newer r151's have a 7.5 input shafter vs 6.5 in the older years. I believe it changed in 1995 but don't hold me to it.

My turn to revive an old thread.
Does anyone have pics of the r151f/split case combo? I ran across this thread among other bits while doing the search function. I'd be putting it behind a stockish 2f in a stockish 72 fj40.
