Could somebody please explain how a LSD gearbox works compared to a non LSD gearbox
I know the basics but have never found out exactly how they work and i am sure there is a lot of people that dont know how they work:D

since FWD use a transaxle that means the final drive is built in to the gearbox. A gearbox with an Ordinary Final drive will have what is called an Open Differential.

Final Drives are often called Diffs or Differential where in fact the Differential of a Final Drive is the gear set between the drive shaft outputs which allow both drive shafts connected to the wheels to rotate at different speeds while a vehicle is cornering in order to maintain vehicle stability and drivability. Positive drive traction is only applied to one wheel.

A Limited Slip Differential will have clutches or some kind of locking mechanism between the two driveshaft outputs that will lock or provide more resistance between the differential outputs to provide positive drive traction to both drive wheels simultaneously.

Honda's ATTS introduced in the 1997 VTiR Prelude is an electronically controlled type of differential where in fact the ATTS unit will actually speed up the inside wheel when cornering to assist in reducing under steer during higher speed cornering. ATTS housing consists of hydraulic pump and clutches which are controlled by an Electronic Control Unit.

Honda's SH-AWD System is a more advanced ATTS type of system that can perform ATTS type of functionality on the front and rear wheel and also control power between the front and rear wheels to assist in vehicle stability and control.

These are just brief descriptions of the above technologies, someone can provide more in-depth descriptions if they like as there are many types of LSD Types. The Gearbox it self will be the same its just the final drive that will have the LSD or not as part of its differential.
