Engine running fine but will not move

whymenow

2003 jeep liberty 3.7l..driving down road with everything running fine when for no reason it was like I moved the gear shifter from drive to neutral..no noise just coasted into nearest driveway.This is a 4x4, checked trans fluid...no smell..nice pink color. Ran main trans through all gears..still would not move..ran auxiliary trans through all gears ...still no movement

ANY HELP WOULD BE APPRECIATED

Well presuming the transfer case is not in neutral (you might check that), it seems like the transmission has failed. It's very hard to diagnose a modern automatic transmission remotely. What needs to happen is that it has to be towed to a qualified shop and a scan done to monitor the line pressure. If the pressure is 0 in all gears, then most likely it's something like a front pump failure and the transmission will have to come out.
