Some more info.
The SUV has a 1,948 cc type 483DL TCIC diesel that puts out 92 bhp @ 4300 rpm and 190 newton-metres of torque at 2500 rpm.

The two-speed transfer case has a low-ratio of 2.48:1 and a high-ratio of 1:1
Electronic shift-on-the-fly is possible, meaning there must be a way of synchronizing the transfer-case with the spinning front axle. It has automatic locking front hubs.

Can anybody throw more light on the Tata 4x4 mechanism, please?

Postscript: My old Mahindra MM540 4x4 had a Spicer-18 two-speed transfer case with a low-ratio of 2.46:1 and a high-ratio of 1:1. Originally the front axle splines were keyed to a flange bolted to the full-floating front axle. Later I replaced the flange with a Warn 29062 Premium Manual hub.
