I recently came upon an interesting bit of kit, as the Brits would say. I've always been interested in the land rover LT230 transfer case. Some version has been used in most land rovers for like 50 years. They are super beefy, with some beefy aftermarket support if needed, they have a high range reduction (discovery is 1.2:1, defender is 1.4:1) with a good low range of about 3.3:1.
What I found was a 700r4 to LT230 adapter kit. I've got a 2wd 60* 700r4 in the garage waiting for it. The combo would put me around 55:1 crawl ratio, which with torque converter factored in, would be around 100:1+. Should be much easier to control in the rocks. And even with the 700r4's 70% overdrive, the high range reduction will bring that up to around 85%, close to the 5 speed OD, and keep my highway revs where they are now, aka, in the "power" band.
The hurdles here are going to be the full time 4wd, so I'll need to make sure I can get the front to stay vibe free, and offset rear output, which may introduce vibes to the centered rear. Eventually I can swap an offset cruiser rear or Dana 60. They also make s part time kit for the case. It'll probably also end up as baby's first automatic trans rebuild.
But anyway, it should be interesting when I get around to it in, oh, say, 3 years :lol:
I got my Bluetooth obd1 connector and the app for my phone, so I'm going to be working on the over fueling issue first and foremost.
