I have a 98 Blazer that just recently bought.... it started having issues with shifting and accelerating.

Anyways, to describe the problem in more detail, when I'm driving I need to slowly accelerate, and even when doing that it seems like it will often rev up and then jump into the next gear, instead of a more smooth transition. If I give it too much gas at once, it will usually just rev up and then start jerking back and forth on the road, as if it was getting engine power, then none, then engine power again, and so on.

if anyone has had this problem i would apreciate the help thanx
