Basically the truck downshifts around 1500rpm when I let off the throttle while cruising.
It did this awhile back and got annoying so I switched out to a full manual vb. I hated that as well so I got a Cheetah vb and also switched from a green stripe modulator to a black stripe. Upshifts are nice but the downshifting is back. I tried adjusting the modulator in and out and it doesnt change much. What could be causing this?
