Power helps the e4 feel less doggish, huge difference in the way mine feels after build than before, no change in Trans.

There have been times, 3rd gear with a load (especially if its combined with a classic WY headwind), a big hill slowly gets steeper, I slowly tip into the throttle to maintain speed, and eventually I'm compressing the floor mat with the throttle, and it won't shift. It will shift if it remains WOT long enough, especially if speed drops. Thats pretty rare though, normally I kind of twitch my foot to quickly increase throttle position maybe 20% and it drops one gear reliably. If I want to go fast the E4OD isn't holding the truck back, but perhaps 96' programming is a little more refined? Punching it at 70 it'll get to 90 in a hurry, passing is no problem.

Edit: my engine is not stock. That does seem to make a big difference.

I'll be stopping by Harbor Freight for a fuel injection pump pressure tester set up on the way home...

In fact it wouldn't downshift when I was using speed control, even losing speed with the throttle wide open rather than downshifting. I know a lot of people wouldn't like that, but I much preferred it over having the trans hunt between gears (if I was losing speed I knew I needed to take it out of OD).

The E4OD in my '97 F-250HD (460, 4.10 gears, 32" tires) is very different. It downshifts much sooner than I want, no matter how slowly I add throttle. I can't use speed control on it with a load in any hills (unless I don't use OD). The 460 with lower gears should be able to lug a lot better than the 351 with taller gears, but this trans won't let it.

Either one downshifted quickly if I abruptly floored it, and gave good performance when I asked for it.

Personally I don't like autos, but even with my complaints about my '97 it's the second-best auto I've driven (the '95 being the best). So I'm still a fan of the E4OD (at least as far as autos go).

Fuel Pressure indicated on the new gauge is 30PSI, either tank...(both are the original pumps) Should be 40PSI I understand...

30-35 PSI at idle is good. Pull the vacuum line off, it should go to 40-45 PSI.

With the vacuum hose on the pressure should increase with throttle. Best test is under load. Pressure should never drop below idle pressure.

Even the new and newer, automatic trucks, not limited to fords offerings, can perform the way youve described and hate.

Its kind of an auto thing to a certain extent but youve been given good advice to troubleshoot, just in case. Good luck

Right or wrong, ive yet to like a factory auto transmission, even modified/tuned. The problem isnt off idle acceleration, its having a transmission that responds in a way thats pleasing, during the many other driving conditions.

Most of the problem is the factory shift strategy. It is programmed for economy IE lug the engine as much as possible. It also locks the torque converter at WOT in 2nd and 3rd gear... So you loose the torque multiplication of an unlocked converter.
