over the past week, this has happened 5 times. I am usually cruising along about 35 mph, not speeding up or slowing. I will try and speed up slightly but the truck doesn't accelerate. After pressing more and more it will finally go. Then this am I coast down my driveway (it's about 1/4 mile long downhill) I pull out onto the street and the truck won't accelerate, staying below 10mph. I pull in another driveway just passed mine and restart truck, everything works fine.
I'm thinking it's pump related, hoping it's not transmission. What you fella's think?
