Well im not sure if i have trans problem or not. If I put the trans in drive and go through the gears when the RPM's get to about 2000 the truck almost stops accelerating, until you give it much more gas, this happens in every gear. but If you push the button to take it out of overdrive and drive like that it doesnt do it. Anyone have an idea?
Thanks

 

Mabe you chipped some gears or once I started my truck and started to long that damaged my flywheel
