Slow to up shift

[Matt Delro]

Hi All,

2013 SVT with 85k miles.

Before the engine is warmed up my truck has a rough time upshifting from 2-3-4 it holds these gears far to long when I’m trying to leave the neighborhood (20 mph) tapping the gas lurches the truck forward without an upshift. Any ideas?

Thanks

My Lightning did something similar on the 1-2 shift. Wound up being intermediate clutches. Have no idea if these transmissions would act the same, though.
