Not sure whats going on but I was on a weekend trip to DC. Everything was fine, except that the last stop we made for dinner before heading home last night. I put the car in reverse and noticed some obvious jerks when car moved backwards. So I stopped, shut off the car. Restarted nd did reverse again. No problems. Back on the highway. Did not notice anything unusual while driving about 100 some miles on 83N ( lots of hills/upclimb). Stopped for gas and decided to do reverse to check it out. Same problem...felt the jerks/hesitation. Decided to just get on the highway and pray that I get home. Got home fine. Same thing again this morning. No msgs on the DIC or any lights whatsoever. Anyone have any ideas what could be going on here ? (103000 miles )
