More 5r55w tranny problems.. help
2003 Ford Exploreer 4x4 5R55W Auto Tranny.
From driving the car it does not shift into 2nd or 5th gear. The O/D light flashes, and the check engine light comes on. Gives Code P0775, which indicates a problem with Solenoid 2.
This weekend I changed the Shift Solenoid Pack with a brand new one from Ford, and the exact same problems still exist. It's as if I hadn't done anything to the car.
I have read somewhere that 2nd and 5th gears share a band in the tranny, could the the problem.?
Thanks.

Hmm.
Well I didn't actuall reset it with my code scanner, but when I first started up the car, the check engine light was off, and the O/D light was acting normal, so I had assumed the codes were clear. I actually had to drive it for a little bit before the lights came back on.
Clearing it with my code scanner may be worth a try.
After thinking about it for a couple of minutes, I rememered that I did have the battery disconnected for a couple of hours while I changed the solenoids. So I am thinking this should have reset the computer..

Ok, I did some resistance checks on my old soelnoid body, and I beleive that it was actually good. So, that wasn't the problem.
Any ideas? Things I can check.
I can get a salvage tranny, I have been considering just swapping it out.

Ok, I was able to adjust my O/D band. In fact after I torqued it and then backed it off 2 turns, I don’t believe it was out of specifications. So, I guess the good news is that I don’t believe my O/D band is broken.
I also checked my ohms between the PCM (Connector 175B, I believe) and fuse 37. I got approximately 29 ohms for all of the pressure and shift solenoids, so based on that I don’t believe I have a broken wires, or bad connection, between the PCM, and the solenoid body.
I did notice the following. I can start out driving the car. The O/D light will be off. I kept accelerating once I reach 30mph, the O/D will start flashing, because the car will have not shifted into 2nd gear.
However, if I accelerate to 25mph, and release the gas, the car will shift into 2nd, then I put my put back on the gas, and keep accleration and it will shift into 3rd and 4th normally.
This reminds me of the time I had a bad vacuum modulator on a C-6. I could do the same thing, let off the gas and it would shift.
But to my knowledge these don’t have vacuum modulators, they are all electronic, so I am really confused.
Anyone have any ideas?
Thanks!
