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....

Also suggested my Speedo cable can be in need of lube, and bouncing. Vehicle speed sensor is inline on Speedo cable. Will relube tomorrow.
We bought a used 1985 Olds Cutlass that was very clean with low miles. It ran well but at certain speeds the engine had a rolling stumble kinda feeling, especially on OEM cruise control. I thought it was something about the "Buick231" V6 lacking V8 smoothness.
Decided to lube the speedo cables. One from transmission to cruise module, then module to speedometer head. Inside the car, near the speedo head, I found this odd looking mirror thing, like a two-bladed pinwheel, that rotated with the cable.
Apparently, it and a little photocell kinda thing, made up a primitive VSS. It was speeding up and slowing down with the sticky cable! Lubing it fixed the cruise and the engine quit stumbling.
