I'd like to know as well, how close the 4x4 auto is to the Jeep's 4x4 auto? Does the Ram use the brakes to stop wheel spin in 4x4 auto, kind of like a poor mans "diff lock"?
lsd is Limited Slip Differential. So when say your left wheel loses traction, after a certain rotation a clutch inside will automatically lock both wheels together. 4wd auto is when the vehicle electronically detects slip and engages the front wheels to put the vehicle into 4x4.
LSD/Anti-Spin is side to side in the rear, 4WD Auto directs power to the front if slippage is detected in the rear.Ok awesome. So LSD is side to side, but 4wd auto is back to front, yes?
So if I am in 4wd auto, driving most of the time in 2wd, and my back left wheel slips, will the truck then engage both LSD to counter the side to side discrepancy AND engage 4wd because it senses the back left wheel slipping?
Operating in 4WD LOW the locker can be engaged up to 40 mph (64 km/h) and will remain engaged throughout the 4WD LOW speed range.
Operating the locker in 2WD, 4WD AUTO, and 4WD LOCK/HIGH the locker can be engaged up to 20 mph (32 km/h). While driving with the locker engaged, if speed exceeds 25 mph (40 km/h), the locker will automatically disengage, but will automatically reengage at 20 mph (32 km/h).
