OK, I'm in 4lo and I'm creeping up a rather steep dirt road when I get to a rocky wet spot. The wheels start slipping and the slip control engages (loud grinding noise from left front). The slip control is supposed to create traction by breaking the slipping wheel and thus giving more power to the other tire. In this case though, evidentally all the tires were slipping, the slip control activated and the vehicle would go no farther. I backed up and retried....same thing. I guess the slip control was breaking all the tires. My question is ......I thought the slip control was supposed to be deactivated in 4lo. Anyone know?
