I've been having a symilar problem of shuttering between gear changes, and also an occational pop that sounds kind of like a peice of sheet metal being twisted. Just started all of a sudden. Would changing the fluid and filter really take care of the problem that fast?

Search google for "torque converter sudder" and you'll find thorough explainations of what's happening.

The 5.4L Expedition has a 4R100. The 4.6L uses a 4R70W. The 4R100 uses regular Mercon fluid.

I had this same problem with my 97' 4.6 transmission @ 100k. I took it to the dealer for a simple transmission fluid change/service and they recommended a "Power Flush" and fluid/filter change. This is recommended by Ford for any shuddering problems. The Power Flush runs a cleaner and conditioner thought the transmission and torque converter. It really did the job. It now shifts like it is brand new. I did not realize just how bad it was shifting until I had this work done. I have had just the fluid/filter changed before but never really noticed much change in transmission operation.

well, my friend took his expedition to the ford dealership yesterday and had it checked out. they found out that it had a bad coil. he is going to put a new coil on and see if that will stop the problem. If it don,t he has only about 200 miles before the extended warranty runs out on the powertrain. We'll see what happens after the coil change, and i'll tell ya what happens. Thank's for the help.

Mine has shuddered since about 50k, and I'm at 105k now. A fluid flush has helped a bit, but it still does it from time to time. Especially if I have to hit the gas above 40mph, after coasting down from speed. Or after accelerating slowly from a stop and punching the gas near a shift point. Nothing seems to have solved it completely. I've had about 4 or 5 flushes since 24k. My truck seems to burn fluid quickly.,,,,98

O.K. so after yall's advice I'm going to take it to the dealer and get them to flush my tranny. But does anyone know why I'm getting a random popping noise? It seems it is coming from the bottom of the engine where the tranny is, and I can feel it through the petal. it kind of sounds like a sardine can being twisted and flexed, like thin metal being hit or twisted or somthing. My CEL is on, but I dont feel like spending another 90 bucks at the dealer for them to tell me that i just need to flush my tranny. This whole thing has got me real upset. My poor ol ford

Identical Issue / Can I change it?
All these responses are very interesting and useful. I have a 4.6L 4x4 automatic, 49,000 mi. that is shuttering in different gears. It started shuttering in OD, now it is also shuttering between 2nd and 3rd. Can I get an additive and transmission fluid/filter and do this myself?? I have never changed this trucks transmission fluid/filter before. I have in many of my past vehicles. Or do I need this power flush thing?? Please let me know. Thank you!
