That hasn't been true in 25 years since it was redesigned as the Soft Locker version of the Detroit Locker, yet some still spread outdated information on it.
Those of us who have actually owned and driven them as I did on a daily basis would absolutely and totally disagree with that. It is absolutely the best behaved automatic locker available for our TJs. You wouldn't have been able to tell one was in the rear of my TJ if you rode around with me. It is only 'quirky' for the first day or two until you learn how it likes to be driven. It's a complete non-issue after that.
