[QUOTE="William Carson, post: 1024770, member: 72711"] Between 40-50 MPH and 1500-2000 RPM under light load, say going up a hill, i have what i think is called a transmission flash happening. The RPMs bounce, transmission seems to slip in and out searching and i get a slight shudder. Only between those RPM's, always at that speed. I have replaced all the coil packs with Denso, replaced plugs with motorcraft, took it to dealer for PCM flash so they flashed it. Learned yesterday they did not flash the TCM and want another 100 bucks to do it. Figured since i wanted the PCM flashed for a transmission issue they would do the TCM as well. They did not replace the sticker on the PCM to show new code word. I did unplug the truck for 30 mins. No change. So i am taking it in to have the transmission flushed by ford, the TCM updated and have them check for any misfires. Is there anything else i need to be aware of or assure the dealer checks out? I would hate for the dealer to "miss" something which will cost me later to have done. First truck and have been reading this board until i am dizzy learning. Thanks! [/QUOTE]
