6R80 Gen1 1st Design Rebuild 

I had a 07 Expedition bought new from the Ford dealer 6R80. The SUV was ok but the transmission was a big pile of junk. Did not even have it 24 hours and already had transmission problems. Took it back to the dealer and they said that it needed a "reflash". It did work for about 3 months then started doing the same thing. It would start in second gear instead of 1 st gear. Every time I took it back to the dealer, they insisted that it was fixed. But only for a while. Then the problem returned. I got tired of going to the dealer and just learned to live with it. On extended warranty then it started having other problems. Driving down the street the transmission would start banging so loud it sounded like someone was running into me. This time I took it to the Ford dealer on extended warranty that I paid extra for they finally fixed the problem. They said that the valve body was defective. They replaced it and then it ran just fine ever since. Basically, I bought a new valve body through the extended warranty to replace the defective valve body from the factory. I learned since that dealers use the "reflash" as a crutch just to get you out the door instead of actually fixing the problem. When you hear "oh it just needs a reflash" demand a real repair and don't let up until they actually fix the problem.

Thank you bro
