this all started on my vaction last week. the week before i had the transmission serviced. it was fine all week and than i pulled my camper to the outer banks, nc from knoxville, tn. we stopped about 2 hours from the coast and stayed the night. the next morning everything started fine until i got to the coast. when i hit the stop lights and tried to pull out from a dead stop 1st was fine and when i hit 2nd the rpms came up and i slowly gained speed. after i got in to what i think was 3rd it was ok. it seemed to have tbl between 15 to 25 mph. it even does it unloaded. the trans works fine if cold but when it gets hot the rpms would climb. if i do not let it get high enough into 3rd and give it to much pedal it would down shift and i could hit redline. i got the truck and camper back home. the camper is only like 9000 lbs and i had about 400 lbs in back of truck. does anybody have an idea what the tbl could be. any help would be appreciated. would anybody know a good place to take it to in knoxville tn. not sure i want to take it back to the dealership. i have about 104000 miles on it.
