I have a Rubicon JL unlimited Manual transmission and have found the reverse gear totally and dangerously underpowered in 2 or 4W On even low grade inclines with any light mud or snow on the ground . Anyone else burning out their clutch till it’s smoking trying to get this beast to back up a hill in reverse . Dealer says there’s nothing wrong but didn’t test it on mud or wet or incline - just black top. Worried about needing to back up from a cliff and never making it back in this rig. Last Rubicon could walk her as backwards up anything !
