With this transmission, it allows your truck to turn in a small radius by keeping the pivot point at the rear axle and the front swings around on that axis under power with the rear locked. Essentially, no forward motion while turning, so you can turn shaper than you would even if you had 4WS (Wheel steering).
This tranny offer 3 mode, 4 wheel drive, 2 wheel drive (disconnect only) and disconnect with break (lock rear tires), base on how far your sevo throws.
