Transmission slipping?

519 Views 4 Replies 3 Participants Last post by  Bigpapa72
I have a 09 with the 4.8l. When I'm on the highway doing 70 mph and ease on the gas my rpms go up but the truck doesn't take off. Anyone else have this problem or know what's wrong? Thanks

how much do the rpm's go up? sounds like it could be slipping..

how many miles on the truck? did you check your transmission fluid level?
