Not sure what i should do with my 5r55e

Check this out, it's tranny info from ford that's been reviewed by the transmission rebuilders of America or something like that, but these guys rebuild tranny's, they have a club so theyre really into it.....you may want to try to adjust your epc solenoid a 1/4 turn clockwise, it says 3/4 i did that it was too much, 1/4 did the trick......they mention it while talking about the" ranger flare" on ranger tranny's, i think page 75 but not sure. https://atracom.blob.core.windows.net/manuals/individual/2000/2000_web_ford.pdf

It is from ford......the admins here at this site loved this, they put it in the tech library here on this site its such good info......im the one who found it online while fixing my tranny, it's great knowledge

All you have to do is click on it, theres like 50 pages of great ford tranny info.....problems,info,fixes, etc

ATRA generally is a good resource.

So the shop flushed the trans and put new fluid and a filter in… did they adjust the bands? Pretty sure like the A4LD it was derived from, there are a couple band adjustment screws. That could be part of the problem.

That said, I also have come to highly recommend shift kits for autos. I went pretty near whole hog on the A4LD in my 92 and it went from a mushy/slushy thing that worked to a smooth operator that was capable of lighting up the rear if you got on the gas too hard and too quick. I got the bands only half adjusted because of rust too. I’m not sure I never want a stock auto any more in one of these trucks. I’m intending on upgrading all of my autos.

I'm probably way off base here, but aren't there several sensors on trans/engine that are involved in the shifting? Seems like if one of those was bad it could cause problems?
I don't know about '99, but I know on my '97 there are sensors, but in fact one sensor in the shop manual, doesn't exist, it was pointed out to me here that it's an error, and there was a bulletin that one of those sensors doesn't actually exist in my year.
But I don't know if it would produce this apparent slipping and others know more.
My '97 5-speed auto works great. The only thing I noticed, relative to the '99, is that if you are as you say Sunday driving it will be in 3rd in almost no time, but it downshifts fine if you get on it. I'd assume if there is actually a difference it's because the 4.0L is stronger than the 3.0L so it doesn't have to rev as much before it shifts (if you aren't on the gas).
But if you do stomp it it'll wind out pretty good before it shifts.
I imagine that didn't help you at all.

So my new valve body assembly with shift kit came in along with my deep oil pan, if worse comes to worse ill buy the damn rebuild kit for $500 and take vaca time to rebuild it myself

 

[Burnsy]

How'd you make out ?

How'd you make out ?

Waiting for my rebuild kit to show up and do everything at once, im hoping to so it all this weekend

So finally I have any update on my transmission, i pulled it out and tore it all apart, the three issues I found, #1 the reverse piston had a blown out gasket, #2 the valve body has a blown out gasket, and #3 the first coast drum when you pull it apart had a bad gear thing, I ordered parts, the new drum came with that gear thing welded into the drum, I put all new clutches and bands, heavy duty converter, reman valve body with shift kit installed, deep oil pan, new sensors, harness, basically everything I could think of when it was out. I also gave it a paint job, so far so good. This in my first automatic I've rebuilt, so im happy, seems to shift it the right times now, still have to break it in, i have maybe 5 miles on it, im sure it has to relearn. I also think that I probably could have just replaced the valve body and the gasket for the reverse piston and that would've fixed my problems, all the clutches looked good and the bands looked great, but then again this was my first automatic

Awesome man

...#3 the first coast drum when you pull it apart had a bad gear
...parts...new drum came with that gear thing welded into the drum...clutches and bands, heavy duty converter, reman valve body with shift kit
...deep oil pan, new sensors, harness...everything I could...gave it a paint job
...happy, seems to shift it the right times...break it in...5 miles on it...has to relearn

Sound like you've done good work!
Any pics, list of vendors & part numbers, things to watch for during disassembly+rebuild,
that you can share would be a great resource for ohers?

Bad news I spoke too soon. After driving for a couple weeks, it still wont up shift when its wide open throttle, half throttle everything shifts fine, i also feel like it should pull harder then it does, i dont understand. Everything looked pretty good inside, so im waiting for my lane pressure guage to come in and test that now, ill keep you posted

There's a lot to those. I had a buddy back in the 70s somewhere who's brother was an automatic transmission man. I'm not sure exactly why but we, several of us, were riding in his plymouth fury, think it was a 4 dr, might have been a 2. I can't say what engine or transmission but he had just completed doing a full blueprint of the transmission.
He probably had a 440, and when he'd punch it out he'd talk about everything it was doing through the gears
At that time I believe I had a little Honda, so it wasn't difficult to understand what he was talking about, and it sounded like a race car going through the gears, every one of them so dang accurate and true.
There is a lot to know in those things if you're going to build one, and there has been for a long long time
I wish you well with yours, but I've already told you about all I can
