    Your disassembly and cleaning immediately preceded this...so, it sounds to me like something wasn't right when you put it back together...

    Not cheap, but much cheaper than a new transmission.

    If the dash display promptly shows all gear positions with no errors, I'm thinking that it is likely not the issue. Also, a visual observation of the linkage itself shows a full throw.

    Probably can conclude hydraulic pressure is available briefly 1 out of 20 shifts and quickly fades. Tapping the tranny pressure ports would be more definitive of course. Dipstick show any particulates? Perhaps drain and inspect a small sample of ATF?

    The gallon I drained out before replacing the solenoids as well as the dipstick after filling it back up is crystal clear ATF with nearly zero particulates.....Just Odd.

    You may start with just disconnecting any of two transmission cooler hoses and checking if ATF flows. That will answer to the question: "Does fluid pump works?"

    To be fair, I am very much at a point where the entire transmission (and motor) need to come out regardless of what I find, so I suppose I need to start pricing transmissions and weighing the cost vs. benefit. 200K on the car, it is due for a timing belt, I paid 2,000 for the car, and will likely never get out of it what I will wind up putting into it (I haven't even priced transmissions). Much to ponder.
