Ok, i had the infamous weird shift in between 1-2 and 3-4 sometimes in my 2002 silvy 4.8 4l60e, but more than not, anyway, so after many researches on this board i decided to get a transgo kit and have it installed, so i took it to a trusted local shop and had it installed, they said everything they could see while they had the tranny apart looked good, they said the fluid looked good and everything. So they put it in and i still have the bump, knock whatever you want to call it every now and then in between the above shifts, not as bad, but i now am thinking its something else, like a u joint or something, so im not sure what is going on now.
