Unidentified transmission and transfercase

[Tim Smith]

I have a couple of transmissions and transfercases that were part of a parts buy and today I decided to open them up and see if they are any good. So far they all look standard to me but this one. I first noticed the difference by looking at the end cap on the transfercase. Instead of being concave as I'm used to seeing, it actually bulges out a little bit. After taking that off, I can see a couple of things different:


The output shaft on the transmission is actually longer than normal. In fact, the shaft is flush with the end of the transfercase.
The gear riding on the transmission output gear is mounted about half way out instead all the way back nearer the transmission side.
The transfercase has an additional gear mounted on the intermediate cluster. I can see the standard gear also in there back behind this gear but I imagine this gear was introduced to pick up the moved transmission output gear (and the new gearing)
The output gear on this transmission has 25 teeth. The standard box I have sitting next to it has 27.

Here are some pictures of the get up.

A regular old transmission and transfercase:

Here are those two end caps, side by side.

Could this be a IIB transmission and transfercase? Maybe a stage 1 v8? I've just never seen this setup before.

Deeper down the rabbit hole.

The stage 1 V8 came with the lt95 box from the early range rover.
My best guess (could be wrong..) is that this is a low-ratio setup found in 1-ton pickups and IIRC the IIB forward control. Good find! :thumb-up:

Oh, I just found the serial number: 24600658. Is there a source book to look this up against? Google isn't helping me too much here.

Agreed. This is definitely a low ratio box. It would be nice to figure out which one. I don't think I will need to keep it for any reason so it would help to identify it for a buyer.

I did find this which is helpful.

That would be an All-Helical, or 1-ton tranny/tcase.:thumb-up:
