I have a 2004 sport trac and when I try to pull a trailer (small 8'x4') the truck feels like the transmission is going to drop. It shifts really hard and almost feels like it locks into full 4x4 when i make a turn. The truck has 60K miles on it, and has no problems when loaded down with 1200lbs, but when that trailer goes on i have some serious problems! Anybody have any idea what this could be from? The trailer i was pulling can be pulled around the block with one hand, yet i cannot even attempt pulling it anymore due to the drastic change and problems is causes. Any help would be appreciated!
Thanks, Jay
