@Truckin222 i meant auto transmission. The Detroit has “slack” like the other full case auto lockers so that it can lock and unlock. With my manual transmission on the trail, it allowed the vehicle to rock back and forth a foot or so. With and auto trans, when you are in gear you have the torque converter constantly taking up that “slack.”
Also, the Detroit will ratchet once you disconnect the rear. When I put it in front wheel drive only, I could tell it would ratchet in turns but most of the time on soft ground the tires would drag so it wasn’t as noticeable. Out west in high traction places it being able to unlock helped.
Down the road if you add cutting brakes you will be set.
