The TBD is a gear operated differential..The True "LSD" uses clutch plates
to control traction. As the differences in wheel rotation happen, the clutch
plates slip to keep things from binding.
The TBD style LSD uses gears that sense and ramp from giving traction from
one side to the other to give the side with most traction the most power.
You can feel it in the snow trying to figure it out so to speak. I have the
locker version in my Syncro for snow usage..It just works..Went up the ski
hill one day without locking the decoupler, so it was just a 2wd esentially
and I couldget her to slip, but with proper throttle control, made it
without getting stuck. I am sure without it, i would have been pulling knobs
to get me off the side of the road.
And you should see how the similar discussions here at SdM have gone..Same
results..slip on ice, then it straightens out and continues on...
