I got the 62 out and finally decided to try the Rodney party trick on the transmission. It's been failing to engage reverse and going into neutral when in 2nd gear randomly. Took it out and abused it thoroughly. It did lots of weird things, lost reverse totally a few times. I kept at it, shifting into park at various speeds, then forcing it to downshift and upshift at full throttle until it no longer failed to engage reverse and began shifting like it should. Took it for a few drag races through the gears and noticed it was shifting way early. Adjusted the t.v. cable a ton, now it shifts firm like it should and revs out in every gear like it should. Reverse now engages solidly, every time and so far, it hasn't dropped out of 2nd gear again yet.
Big test will be cold start and drive. It was always worse when cold. Been that way since I got it but started really having issues the last two trips out.
With 301k miles on it, it has lived well beyond what it should have. Just thought I'd try the trick before I yanked it apart to find out the governor and valve body we're sticking and the rest was still functional.
