My EB F150 is at the dealer right now for harsh/stuttering down shifts. They did the flash to correct the hard up shifts. Apparently Ford issued a SSM to replace the clutches in the transmission with higher pad count. I can't find any info on the SSM online, but I will ask for the SSM number when I pick up my truck. They told me if replacing the clutches does not solve the issue, or if any new issues arise, then the transmission will be replaced with a factory new one.
I'm kind of aggravated over the whole ordeal since the truck only has 2,760 miles on it. I started noticing problems around the 1,500 mile mark and they got progressively worse from there. Up shifts were so hard it felt like I was being rear-ended. Down shifts were so rough the entire truck would shake.

Just had mine flashed due to hard shifts. The tech said both a TCM and PCM update was available. It appears to have fixed the issue for now but I need to test it further.

It's actually extremely hard to make one do a 2-1 coasting downshift in the first place - you can't go faster than 7 MPH, if you do it will shift into 3rd gear and never go back into 2nd anyway. Mine appears to have this problem, it's not terribly aggravating since they get them out of 2nd as fast as possible anyway. I'll ask them if I should be concerned when I have the oil changed.

That is exactly what mine is doing. Its not really bad, but it is noticable. Even my wife who normally doesn't say much about car noises or jerks asked if that was normal. I wonder how long it would be I would be out of a truck to get this service done...

Should only take a day or so. It's them getting the parts in is what takes the longest. I took my truck last tuesday. Wednesday they found the problem/tsb, pulled the trans and ordered the parts. Parts arrived Friday. Dealers trans guy wont have time to do it until Tuesday(tomorrow) and the truck will be done by Wednesday afternoon. So, for me, a week and a day if all goes according to their plan. lol

You can always just lockout all gears above 2 and force the downshift from 2 to 1. Easy peazy :-)
I'm having the same 5 to 4 hard shifts too. I can actually make it do it on the fly by controlling the gear lockout. I'll get up to speed nice and smooth and soon as the truck shifts into 5 and settles itself into 5, I'll lockout gears 5 and 6 which in turn forces a downshift to 4. BANG!! Every single time. Now, I can completely avoid that by first taking my foot off the gas pedal, letting the truck start to coast while still in 5 and then lock it out to force the downshift to 4. Nice and smooth, like you'd expect. But that's the difference.....I have to first the truck start to coast itself along before I force the downshift via lockout.
For those that are curious.....I've tried this in just plain manual mode and it's not as easy to replicate. I guess because there's a different TC lockup pattern or something? Don't know why though. But in auto using the lockout method above, every time.
I'm at 5.7k miles right now and getting close to oil change time. When I take it in, I'm leaving it for them to deal with this issue. Hopefully they'll fix it.

It will be 2 week come Tuesday (7/5) that my truck has been at the dealer for the transmission. If it is not 100% right I might need a lawyer and someone to bail me out of jail.

Had mine at the dealer this week and they looked at my 5-4 and 4-3 harsh downshift and as usual, they siad no issues and all updates are current. I am sure Ford will issue a TSB soon, just wish they would hurry up.
