I've been having a lot of problems with my 2000 F350 5.4 V8 automatic. When you put it in reverse it gurgles like a diesel, the rpms drop way below 1000, and it just sounds like all power is dying (my alternator and battery are fine). If you just keep your foot on the gas and back up it'll surge backwards on its own WAY faster than you want, but if you take your feet off of everything it stalls out. It's also been giving me problems going down the road where the rpms will go up between 3000 and 5000 but it'll just sit at 30 mph until it finally kicks back and goes. I'm running 93 and have been using fuel injector cleaner and it's not helping. Any advice would be greatly appreciated!

 

It sounds as if your vehicle is trying to compensate for incorrect inputs to the PCM. I know we don't have much to go on, but this is what I would try.
Check the connections of all the plugs at the trans. Open them up and look for corosion which could be giving alternate paths for wrong connections.
Then Check all your vacuum lines for broken or hose problems. I don't know at this point if a poor ground connection could do this , anyway check every one you can find. Questionable grounds can drive you nuts. Does it do these things in park?,,,,,,,,,,hanky

 

It runs fine in neutral and park. Someone else on another forum suggested pretty much the same thing as you, so I'm definitely gonna give that a shot. Thanks for the input!
