Intermittent hard shifting can be a sign that something is starting to fail or there is some junk floating around that gets stuck in the valves every once in awhile. Also might be the computer boosting pump pressure to compensate for something going out(least that's what I have read).
You might try a complete fluid change including the torque converter. Sometimes this fixes it. Or you might try one of those power flushes at a tranny shop.
I am no tranny expert so you might need to talk with one or hope one of the guys has better answers.
Good Luck,

Had the same problem with my '94 F150. Trouble code pointed to the MLPS. I replaced it with the upgraded '95 sensor and wiring connection kit. Fixed it right up. No more neck breaking shifts. Good luck....Van

Sounds like you've got the same problem as me (94 5.0L E4OD). I've had the MLPS replaced, the speed sensor on the rear differential replaced, the ABS module replaced and no luck. I still get erratic hard shifts. It always seems OK first thing in the morning but on the way home after work it often starts to act up. It's at a local Ford shop again right now and I'm waiting to hear back from them. Have you pulled the engine codes? Are you getting a 452 code?

Ill be following this thread with big interest. My 97 F250 E4OD does the same thing,(SLAMS into gear, at a higher RPM too) just started doing it about a few months ago. I'm debating to pay to get the code read or buy a reader myself.
One thing I did notice, If I start the truck and let it idle without touching ANYTHING, for at least 30 secs the truck runs fine. If I start er up and go, it's almost guarenteed to shift like crap.

Code readers are fairly inexpensive - well worth it in my opinion. I still haven't driven around enough to be sure the problem is fixed. I'll write again when I'm confident it's fixed!

Good luck. Since they replaced my speedometer (PSOM) I have not had any of the problems I had before and I've been driving it around for a while now. It seems like in my case at least the 452 code (bad vehicle speed sensor signal) was as a result of a bad PSOM and this resulted in one confused transmission!
I'll be interested to hear what they say about your truck

check the little plastic gear on the tranny end of the speedometer cable. it sends the signal for the speed sensor. it took care of my initial problem. now the damn thing wont shift into 1 or 2 at all so im back to the code analizer. good luck

Well I had trouble understanding the message, but my problem points to a speed input / sensor located in the transfer case which needs replaced?, according to Ford shop. Estimate was $225. I'm going to get more details when I can talk to the tech., but for now I just told the counter to go ahead and order the parts I need.
