Possible transmission Solenoid failure
My TX has only 2 solenoids, one for Overdrive one for the torque converter lock up. It is a chrysler A-500 from 1989, also called the 42-RH. Basically a 904 with a overdrive housing tacked onto it....

As an Update:
I decided to go ahead and get new solenoids drop the pan and valve body and just do it.
In preparation for dropping the valve body, I spent some time cleaning the TX above the pan, where the electrical connector and shift lever exits the transmission. Brass Bristle brush, spray silicone, rags q tips and compressed air to really get things spotless.
While doing this, I remembered that I never bothered resetting the engine computer, after rebuilding the wiring harness and lubing Speedo cable and inspecting VSS, and did so.
Since the exterior cleaning, but more likely the ECM reset, Overdrive has been working as it is supposed to, for 2+ weeks now.
Valvoline ATF+4 is $6.50 a quart at wally world. I might return it, I might use it. I am going to await the return of symptoms before doing anything else.
