Default 4r44e lost second and OD

Help! First post here but have a 95 XLT automatic that was given to me. It had bad head gaskets, so I have repaired those and been driving it for roughly 3000 miles total. The auto tranny shifts hard from 1st to 2nd, and sometimes 3rd but always seemed to work fine otherwise.

The other day my son was driving it and it seemed to bog all of a sudden and the OD light started flashing. He pulled over and called me. Once I arrived, we were able to get it home by starting in 1st gear, shifting to 2nd but it never changed to 2nd, then to drive, and it banged into 3rd gear and that was where it stayed, We got home though.

I checked fluid and it looked good. I went ahead and pulled the transmission pan and filter. it looked pretty good as well. Nothing jumped out at me. There was just a tiny bit of metal "glitter" in the pan that reacted to a magnet, but I cant really feel it with my finger. I could have placed it all on my fingernail and it would fit so it was just a tiny amount. Any idea what the issue would be? I read that sometimes a SSB solenoid part may be out of proper location that could cause the symptoms, or a bad valve body gasket could be the issue.

I need an inexpensive repair to keep the truck going. Do you think the issues may be with the valve body, or internal to the rotating assembly in the transmission?

Drop the valve body and check the gaskets first, might want to make a template for the bolts, all different lengths.

You can check for gasket problems by shining a flash light around the edge of the valve body without removing it. This transmission had a habit of blowing pieces of gasket out the side. The location of the break determined the symptoms. Also look in the pan for gasket pieces. If you have a bad gasket, Ford had a TSB that replaced the loose gaskets with some bonded to a separator plate that can not blow out.

While the pan was off, I decided to make a few quick checks on the solenoids and the fuses. I had read where the PCM that controls the transmission can sometimes have a blown fuse. Anyway, I R/R and checked each fuse associated with it, and all looked good. I checked each solenoid with a ohm meter for shorted condition and resistance (all checked fine). That is where I noticed something. Prior to checking them, I removed the large plug than connects to the side of the transmission. It came off VERY easy. I was surprised at how easy it slipped off. It would slip on, and slip off each time I tried. It would not fall off, and did not seem that it would shake off, but it was not as secure as I would have expected. I wondered if there is a clip or something that would hold it more secure.

Anyway, I made sure to press it on as secure as i could get it. Then I reinstalled the old filter and put the pan back on. I purchased 8 quarts of super tech mercon V and added to the transmission. After the 4th quart, I cranked the engine and had it running while adding fluid and checking. I noticed that the OD light was off (and not flashing). I ran it through the gears and had it going from r to d to 2 to 1 and back and forth (while stopped). Then I checked the level after 7 qt and it still was low, so I add the 8th qt. This brought it up to full.

Then I test drove it last night and it worked properly. I drove about 20 min total. Today I have driven it to work, back home and back to work, about 15 min each way on the interstate. Shifting is fine without the hard shifts it had before. Feels very normal. Up-shifts, downshifts while in D. I can turn OD off at will. I have engine braking in 2 and 1. It will take off in 1 as well as 2 correctly. R is fine as well.
