Im having similar issues with my 99 f250 sd 5.4 AT. Truck started limp mode and trouble codes :-huh
P0743
p0755
p1747
p1409
p1754

Thanks for any help guys!!

Did you bother reading the WHOLE thread that you joined?

Problem with my F-250 was bad o2 sensor.

Yes i have read the whole thread. I have no blown fuses in main fuse box. Would the o2 sensor still be the most likely problem? I will try a new o2 sensor tomorrow and let u guys know the result.
Thanks for your responses!

You should have stated such, we are NOT psychic. You have TWO fuse boxes, you have to check the correct specific fuse(s) in the correct box.
No
The result will be "It didn't fix it".

I've got a 2004 f250 5.4l
I'm getting a p0135 p0155 and p0755 code
wondering if this is an electrical issue

Yes, it is.

Where should I start tracking it down

For the P0755 the problem is usually in the wiring harness between the PCM and the transmission. It's less likely to be the solenoid itself, or even less likely than that, the PCM itself.

Some places I've read says something about a fuse do you know what fuse I should check

I don't know any way that a fuse could cause this.

If it were a fuse, you'd have a lot more codes, not just three. Probably at least a dozen. perhaps you do but didn't advance far enough through the scan tool's screens to see more of them. Check your scan tool.

Fuse F23 would be the culprit if you find you have several more pages of codes on the scan tool.
