3 gear transmition works as follows
Diff rotates forwards, Idler in transmition rotates backwards which means spur gear rotates forwards. For the spur gear to rotate forwards the motor has to spin backwards eg anti clockwise which lifts the car.
It does not mater which way you have the transmition mounted LHD or RHD for the car to go forwards the spur gear has to rotate forwards hence why on the RHD you have to run the motor in reverse
4 gear transmition works as follows
Diff rotates forwards, Idler in transmition rotates backwards which means spur gear rotates forwards, then additional idler on motor plate rotates backwards and the motor has to spin forwards eg clockwise which pushes the car into the ground and gives you more rear end grip on power.
4 gear is the way to go wether it is like the X6 and has the extra gear in the transmition or like me you come up with a make shift way by using an idler on the Motor plate.
