Hi,
Thanks for the reply and explanation. I would like to differ on the quoted part only. TC size won't increase. Why? Look into the TC operational mechanism. There is only an interlock in the TC preventing it from slotting into 2WD-L. If the interlock is removed 2WD-L is quite possible without adding any other component.

Even Late BD Sir also touched upon this earlier. Quote:

That's why T18 transfer case has an interlock. As long as 4WD is not engaged, the smallest lever will not go towards the front, means low will not be engaged. |
Remember these gear levers. Heavy load-hauling trucks do have such setups. They have huge gearbox to accommodate the extra cogs! I believe TC reduced this enormous size of GB by providing a single reduction gear system. The net result is quite similar. |
