Hey guys have a question about something my transmissions been doing. A little background, 2002 Supercrew w/5.4. Bought the truck last October and the guy said the trans had been rebuilt with a monster kit. Got a bunch of receipts when i bought it but none on the trans, so i dont know any specifics about it. My problem is lately when it shifts into 2nd gear there has been a sort of a bog for about 1-2 seconds then it kicks in and goes. I do have a hypertech programmer but didn't mess with any of the trans settings since it says not too if you have a shift kit or so-on. So does anybody have any idea what would cause the bog? If i missed any specifics just let me know and thanks for the help.
