Tranny thump

Tranny thump
I've searched everywhere and still haven't found a cause or solution to my problem.
When I shift into drive or reverse, the whole truck makes a loud, visible thump. It thumps every time it shifts gears, up or down, while driving. The atf level is where it should be, that's not the problem. Any solutions or ideas why it's doing this?
And not sure if this is normal or not, I wouldn't really know, but when I'm driving, say 45mph, and I let up off the gas and coast, the truck will thump. When I put my foot back on the gas, it'll thump again. This isn't when it wants to shift, only when I take my foot off and put it back on the gas.
The more important problem here is the tranny thump. Help? Thanks.

Check the drive train obviously but your local Ford dealer can advise if tranny software updates are available for your specific year tranny. They can do it at the service desk in the service bulletin section of their computer system (tell them whats wrong, givem you VIN, they'll advise if updates are available the decide if an appoint will solve your prob). I had a similar expeience and a software update solves the hard shifts. 2007 FX4 II.
Good luck dude!
