Hi, I understand the different ways TC works. However I do not know what actually occurs on a Defender with TC. Does it brake the spinning wheel (To get a diff lock effect of driving the wheel with traction or weight on it). Or does it use suspension and diff sensors to apply drive/brake to specific wheels, or possibly Diff locks though I am sure I have never heard of a standard defender with diff locks? I am interested if I should have bought one with TC and would it have been better off road? Thanks. Jonathan
