4r100 shifting issue
hi everyone,
I have a 99 superduty, I have to let off to shift to second around 2300-2500, and it if I accelerate to hard in second it will just rev like in neutral. Rest of geara are fine and shift fine. I put new electric solenoid pack and accumulator valve body with upgraded sonnax valves. But problem still the same. No flashing o/d.

Hi jschlaf, welcome to FTE! Sorry you've found us by way of a transmission problem.
If you've replaced solenoids I imagine you've ruled out low fluid level. Hopefully Mark K can chime in on this one. Sounds to me like you're going to need a rebuild.

Yes fluid is full, I flushed trans and changed filter when I changed accumulator. Thanks mark I'll have it scanned again. When I did have the blinking o/d. It was the eps. But I didn't know I could still be getting codes without o/d light flashing.

there is a black plastic module on the driver's side of the tranny, i think it is called the park neutral drive postinioner, it is linked by cabel the shfit lever, have that checked out. had the same problem as you,, replace the part and works great.

Ok thanks, that would make sense maybe becuase my shifter is hard to move too. Which I have read could be that sensor as well.

I wish, my buddy just paid $189 for the local Ford dealer to scan for trans codes. Result was "you need a new trans, $4950 for a Ford reman.".

That's insane for generally less than 30 mins of there time to drive down rd with scanner hooked to it. Then half the time I doubt there diagnosis is probably wrong it's easier to put in a new tranny than fix the one that's in it.

And if it ever comes down to changing tranny it would be bts or John woods for that kind of money, I hope that price was parts and LABOR.

yeah right, that's their price bringing the truck to them. I do believe they meant parts and labor, otherwise their more loony tunes than I figured. I told my buddy to go BTS if he was going to drop that coin, but he's not, we're looking for a local re-builder that can do it for ~$1500.

And that's why I've been recommending people find a good independent shop. You get better work for less money.
