i have a 1992 ford explorer 4x4 4.0 engin with a4ld auto transmission the problem started about 4 months ago when i changed the trans fluid and filter the truck would drive fine when warm but when the truck was cold and you put it in gear it would move 10 or 15 foot and than it would stop moveing for a few seconds almost like it was not pumping fluid and than it would engage and move fine and than do the samething over again until it warmed up a bit than it would run great yesterday 12-16-03 the truck was started to go to work and warmed up when i was ready to go the truck backed out of the drive went down the street about 3 blocks and did its deal with not moveing about 5 foot from a stop light when the light turned green it drove about 30 foot and the truck wont move anymore in any gear it starts revs but dont move it made no sound before it stoped moveing it does no leak any fluid and everything is topped of fluid wise the linkage moves when shifted cable is fine but wont move

help Thanks rick
