shift solinoids. but first check the transmission fluid. also this has the 4.9l right? auto zone sells shift solinoids for $30 each . if it is 4.9l it has the 4t60e transmission. i think thees shift solinoids are in the side transmission cover. when u replace the solinoids use a multimeter to check the wiring harness. disconnect the wiring harness located on top of tranny. unplugg shift solnoids and conncet multimeter to connector terminals put meeter on continuity it should not beep . if it does internal wiring harness is bad.( BEFOR DOING ABOVE : CHECK PCM CODES. ON INSTRAMENT CLUSTER HOLD WARMER BUTON AND OFF BUTTON DOWN FOR A FEW SECONDS AT THE SAME TIME A SERISE OF CODES SHOULD DISPLAY WRIGHT THEM DOWN AND EMAIL ME AT BRANDONDAY87@YAHOO.COM. FOR FURTHER ASISTANCE.
Dirty transmission filter. Most "service" places only pump out the fluid through the dipstick tube and tell you that the filter will be OK. That way they don't get an ATF bath when they pull the pan. I'm guessing that the crud in your tranny is pluging the filter after a few miles, when you shut it off, the fluid runs back down, washing the dirt and metal pieces back into the pan.
Try a tranny service change a place that changes the filter the pan gasket and fluid not some of these quick places that just drain a couple quarts out of the tranny lines and thats it that wont help but a complete tranny service should help.
