Can anyone identify what model this transmission came from? I myself am totally stumped and that rarely happens when it comes to this kind of thing. Some of you who are as much of a parts nerd as me will find this to be a fun challenge. It has very few clues by which it can be identified and I will list them below.
I know it’s a H150/151 or maybe even a 152, but it has some bizarre twists that makes it a bit of a mystery.
I’m confident I have all the right combination of parts to make this setup work behind a 3FE powered fj80, but I’d really like to know what this trans came from originally for future maintenance and parts support.
It’s obviously suited for a 80 or 100 series, but I don’t know of any specific model that used one quite like this. It came with a 3F bell housing, but I am 100% certain it was not a 3F transmission to start with and here’s why…
1. The input shaft is the same as 1HDT and/or 1FZ, 14 splines and much bigger diameter than a 10 spline 3F input shaft
2. The oil pump is always on the back of the 80 series H15x transmissions and this one has the oil pump integrated into the front bearing retainer. Which brings me to my next unsolved mystery…
3. What the heck is up with this bearing retainer? No release bearing that should fit does, not 1HZ, 1HDT, 1FZ or 3F. No, the bearing that works turns out is for a 2H/H55F combination and the retainer is also the oil pump. Something I have not seen on any Land Cruiser I’ve worked on.
4. This thing came with a HF1A part time case, which I was going to save for another project, but turns out that the splines on the back of the transmission won’t fit your regulator 80 series full time case? They only fit this part time case specifically. The drive line flanges on the transfer case are also larger than the 80 series (2 3/8 vs 2 1/4), thankfully the package also came with new driveline ends that do fit.
