ID my tranny: e4OD or 4R100
OK, so I'm not sure if I have an E4OD or a 4R100. The trans code is E on a 1998 F150 extended cab, 5.4L Triton V8, 4x4 (Off-road package and tow kit). There is no drainplug on the pan. The pan is not flat. The pan has 20 bolts. The dipstick says MERCON and is yellow.
Yeah yeah, I did a search. You can feel free to make fun of me, as long as you tell me which tranny I have

PS advice is appreciated as well, as I'm about to attempt a trans fluid change

It's going to be hard. 1998 was a transition year. I don't know of any specific things to look at to tell if it is a 4R100 or E4OD.
I *THINK* the 5.4L in 1998 had the E4OD. I'm not certain.
The 4R100 and E4OD are very similar, but the 4R100 is not just a renamed E4OD. Many internals were changed to increase the torque capacity.
In the AODE/4R70W, there were bigger changes. The biggest one is that the gear ratios changed. The 4R70W has a lower first gear. This caused the gear set to be a larger diameter, which made the case grow to fit it. If you measured them you would find that the 4R70W case has a larger diameter.

Yeah, and thanks for not clearing that up for me.
I guess it really doesn't matter, as the fluid change procedures are about the same. I have the pan off now (wow! more fun than the log flume at King's Dominion without a drain plug!), and the TC is drip drip dripping itself dry.
Query: how much metallic gunk is normal down around the magnet? I ask because I have the usual metal "fur", but in addition I have a decent-sized hunk metal that is worrying me. It is very very thin and narrow (like a strip of gold leaf, only steel), and if you were to wad it up (its very malleable since it is so thin) it would make a good-sized spitwad. I'm under the impression that this is not normal. Otherwise the tranny pan is VERY clean and the fluid is bright, not varnished. The tranny acts okay, no clunks, grinding or other strange sounds/vibrations.
Thanks,
Mike
