I picked up this transmission in trade a few years ago, and do not know what I have. It came with a 3F bellhousing.

Thanks.
Suitable for a 40, or should I do some more trading?

Could work, but the extra length due to the extension housing would make for a very short rear driveshaft. An H42 from an earlier FJ60 or late FJ40 might be better. Better yet, a low-ratio H41, but I'm holding onto mine
. If you found a shorter H42 you might want to go with a matching bellhousing and sell/trade the 3F bellhousing.

I figured I would put the three speed transfer case on the back. Some vendor on here, I believe, makes the adapter. I just re-built the transfer case a few years ago.
you can install a 3 speed transfer to an earlier H42 made before 81.
I'm not aware of a setup to let you install a 1 piece transfer case to a 4 speed that originally came with a splitcase.

Thanks for the info and advice, because even though I have done damned near everything else to my 40, I am not conversant on transmissions. I just know that I have the original 3 speed from my 69 sitting behind a 2F out of a 77 with a later clutch.
I have a 4 speed in my 74 Pig, but have never looked at it.
How do you identify H41, H42, etc?
The easiest way to tell an H41 from an H42 (with the transmission out of the vehicle) is to turn the input shaft on the transmission, with the transmission in 1st gear, and count the number of rotations it takes for the output shaft to go one revolution. The H42 is 3.555:1 and the H41 is 4.925:1. Look here:
Transmission and Transfer Case Specifications: Off-Road.com
As far as I know, the H41 was never offered in the US market. I have one in my '76 FJ40, mated to the 3-speed transfer case from my '71 FJ40, using the older 3-finger clutch from the same vehicle. That combination, along with the 4.11s in the differentials and smaller tires (BFG LT235/75R15 ATs), gives me the low gearing I need for the trails around here. I've got a low mileage (~70,000 miles) H41 out of an '84 HJ47, mated to the original split transfer case - I just might install it in my '84 FJ60 when it's time for another project.
Have a early H41 as well. Tailshaft is worm and plan to get around that using a Fairey Overdrive that the splines run on a different sections of the tailshaft. Poor man's version of a H55F. I also picked up a H41 from a 84 HJ47RV. While not low miles it also had the two direction PTO. Even a blind squirrel gets lucky every once in a while and finds a nut (ten miles away in a junk yard). You didn't mention it but guessing the transfer case had the hand brake attached to the back. Thought I have located a H55 in Australia for a 4X series. Was located in the middle of no where in a HJ47 just rotting away. Turned out to be a four speed but pretty much figured that out ahead of time doing some research. Almost all LWB 4X series came with four speed from the mid seventies on and after 7/80 the hand brake continued on the transfer case not the axle. Website wasn't in English but only one one model LWB in one market that a cable was going to that axle on a LWB. So I'm guessing yours has the hand brake which is wasted on a 60 series. Not sure what you paid for the later H41 and transfer case but mine I know I could sell the hand brake and be money ahead. But I guess you already know that transfer case/hand brake is worth as much if not more than the transmission, even a H41.
I bought my '84 H41 used from Chamba when he lived in Santa Fe. It's mated to a rebuilt '82 transfer case from (I believe) an FJ60, so no hand brake. But I bought it thinking it would go in my '84 FJ60, and I might still do that.

I found a couple of H41's and H42's at Mark's Offroad and a couple of other sites. I won't be doing anything to my rig until after tax season, but I will revisit this thread and others then, to figure out what to buy.
BTW, thanks for all the info and feedback

Toyota had the five speed in 40/42 LX models in 83 and 84. Driveline can't be that short without the hand brake on the back of the transfer. Before 79 the floor was lower under the seats. If that was worse than the fuel tank being there not sure. The 3F bellhousing clocks the transfer case down a little on the passenger side. Again not sure if that was used on the 40 series, but I don't think so. Still locating parts and doing as much research as I can just incase this blind squirrel gets lucky again and finds the correct 40 series top cover for the H55F. That's the one piece I'm losing hope on.
To the OP 60 series transmission would be a better fit in your FJ55. Still would have to deal with the hand brake but have room on the back of the transfer case and think Georg @Orange45 was working on rear axles with the hand brake. Biggest advantage is the split transfer case. Much stronger and quieter than the one piece.
The best split transfer case IMO is the FJ62 split case, which can easily be modified to manual front drive engagement using OEM parts. I had trouble finding used parts so coughed up more $$$ to get new parts. The FJ62 case has bearing supported output gears front and rear.
I've read that. In my stash of parts have a low mileage 90 FJ62 transmission and transfer case that's been store inside for over twenty years. I'm not opposed to keeping vacuum shift but would operate with the 40 setup instead of the troublesome solenoids in the FJ62. I know in Mark's thread on rare transmission cover you bought the low range switch in the FJ62 transfer case. That switch wasn't to let you know it was in low range but to operate the vacuum solenoid to be sure it was in 4WD. Which I wouldn't be surprised if it did the same thing on the one in the fire truck. Later 4X series used a solenoid in market that still got a vacuum shifter. That other cover had a shorter shift rod which makes me.think three speed not four speed. Find it had to believe Toyota would have. Optional H41 four speed that allowed you run low range in 2WD with a granny transmission.
Understood, but since I had the switch already installed I figured why not add an indicator light to the dash in newly available real estate.
I bought my H41 from Spector; they import them from Australia and rebuild them. If you buy at their traditional end-of-year 15%-off sale, you can get one rebuilt for about $800 IIRC. I'm very happy with mine, combined with an Orion transfer case, my stock (for my year) 3.70 diffs, and 33" tires. A great combo that gives decent rpm on the highway and nice low gears for the trail.
