stuff the ABS and 4x4 issue, you can rewire it so you these systems don't affect the 4x4 operation anymore!!!
at the end of the day we dont have hubs that can unlock so we will never get "2LO".
If the D40 was like the Hilux and ran vacuum controlled hubs, then we would be able to to it easy.
Yeah that's another way to do it too, but I'm not sure I want hubs that could unlock on me when I needed them to be engaged because of some fault.
In a straight line, or on grass/gravel, 4LO in our cars isn't a problem.
I think sometimes having a lower first gear for takeoff up inclines with a load would be handy - but that's where the auto comes in. Lockable front hubs or not, there's no way to change the final drive ratio on-the-fly other than the factory set gearing unless someone develops a new transfer case which has gearbox functions, and if they do, I'd be asking them to provide those functions pre-engagement of the front drive shaft, allowing those extra gears to be available in both 2WD and 4WD.
Then you'd have the best of both worlds.
I doubt you'll get that on-the-fly switch happening. The transfer case would eat itself first, it's not like a gearbox where part of it can remain turning while the gears change. One day it might be different, but there's a reason why you have to stop, put the car in neutral, run around it twice tapping your hands on all 4 indicator bulbs, get in, flash the headlights twice, adjust the rear view mirror, step on the brake, use the LEFT indicator once, then change from 4HI to 4LO (this works, by the way).
There's only ONE servo that manipulates the transfer case and it rotates through 270 degrees to achieve it (90 degrees every second, so it takes 3 seconds to go from 2HI to 4LO). There's a whole section of thread on it, the first post is here, and you'll see photos of the wiring job plus discussions and pictures on how to make it more workable inside the cabin.
We can't escape the limitations of the transfer case (vehicle must be stopped) but you'll see that there are ways to get around the computer. I was hoping (for our boat owning friends) that we could find a way to engage "2LO" but with a single servo that just isn't going to happen. If there were two - one to manage the engagement of the front drive shaft and the other to change the drive ratio, then no problem - but there's just the one, so we're (for now) stuck with what we have.

So, am I correct here?, if your ABS gets damaged out in the middle of the bush, you can't engage 4WD????
If that's the case, then I'm off to Jaycar.
Funny this thread popped up, just the other day I was thinking if there's a way to replace the servo with a stick.
Apparently You can still get 4H but Not 4L, BUT i have read that you can trick it by turning the car off selecting 4L then turning the ignition on wait for it to engage then start the engine, HOWEVER i havnt unplugged one of the sensors to disable the ABS in order to check if that is correct.
that post is similar to what I have done tony, except I used a 3 way switch in reverse polarity setting for one...
Who know is you would get a rwc for the car after having this done, but without having the abs or 4wd light illuminated on the dash, whoudl you even suspect most mechanics to even look?
