Random transmission problem
My transmission was rebuilt about 40k miles ago. Recently drained pan, replaced filter and refilled. When the pan was off it had some black stuff around the magnet. I called Brian at BTS and he felt that it was clutch material and said that was normal. I cleaned the pan and reinstalled.
A couple of weeks ago I stopped my truck on a steep hill to talk with some utility workers that were on my property. I finished the conversation, started truck, shifted to drive and promptly rolled backwards. It was like the truck was in neutral. I tried again and made it up the hill but had to use considerably more throttle than normal. I drove the truck for a few miles and it did not shift properly (felt like I had to back out of throttle to get it to shift). I shut truck off and restarted and everything worked fine.
Since this event, I have had a few times where I placed truck in drive and nothing happened. Each time I would restart and everything worked fine.
I have checked the wiring and plug and they look fine. I am guessing a solenoid is acting up. I have no codes stored. Any advice?

The fluid level is maybe a little over filled. It is full on the hot side of the stick when cold. I will drop the pan and change the filter. I put a filter from NAPA on but it did not seem to be made very well and did not fit tightly on the transmission pick up.

That doesn't mean anything. It could be slightly overfilled, just right, or low. If you are checking it cold you just don't know. I know the dipstick has a cold mark, but it is meaningless. The person that designed the dipstick didn't understand that.
You MUST check the fluid with the trans warmed up and idling in park.

My old 1992 F-250 used to have checkb while warm in neutral stamped on the dipstick. I quit doing it that way when I bought this truck.

Oring
When you changed the filter, did you happen to notice if the old Oring on the filter came out with the old filter? they tend to stick up in the hole, if it is still there, your new filter probably did not seat correctly. Every time I have changed mine, the oring hung up in there and had to be pulled out with a pick.

I added 1-1/2 quarts of fluid and now it is full when up to temp. Hopefully that will make a difference. If not I will change the filter.
