early 99 PSD. Auto.

New Issue:

I have looked and cant find this issue....

when I'm driving down the road and cruising about 1500 RPM, i go to excellerate it shakes until it down shifts.

in my mustangs i would start looking for vacuum leaks. it seems like it doesnt has the vacuum pressure it needs until it down shifts.

any ideas.

thanks in advance
