Default tranny issues

So recently ive been having problems with my tranny. its auto. if i am pushing the truck a bit hard and get to say a red light i will not shift back into 1st most the time. and when im accelerating it almost feels like a fuel cut but i lose alot of speed going into final gear. not sure if thats a good enough explanation but if anyone can understand that let me know if you have any thoughts

sounds like 2 gears are trying to come one at the same time??? does it pull you down for a second then shift into a higher gear an take off like nothing happened??? might do some preventitive maintenece (SP) and have everything above the valve body re-adjusted.

now that sounds like to much throttle pressure. that is the black cable that runs from your IP to the tranny. i dont remember the specs so im not gonna guess on the adjustment you can fry a tranny if it is adjusted wrong. check into that

youd know if its slipping. i would do a fluid change and take the pan off and make sure the bands are torqued to spec while your in there. then look at sensors. dodge auto trannys are a pain to deal with hope you find the problem
