Thanks for the heads up on that, I was going to say - I saw you post about the output speed sensor saying you had built a small circuit to simply divide the number of pulses from the sensor by 4, so I figured something had to be changed out, or I could spend the evening hacking up a TTL board with some flipflops on it or something. Didn't remember enough specifics to actually figure out which sensors were the ones that needed changing, or which years they changed over in though.
Not sure about WA-4x4 but my transmission is doing some really funky stuff. It randomly unlocks the TC or slips the clutches (not sure which, I suspect the former) which seems like either a fluid pressure issue or an electrical issue. It also overheats quite often, lurches while shifting occasionally, and on Saturday third gear disappeared and it went into limp-in mode, leaving me with only first (or second, I forget) gear working, and even that was starting to slip badly by the time I got home. It's been abused though, I had been half expecting this for months - the previous owner never changed the fluid in it, and it had been starting to randomly slip severely if I got off the highway and it got even slightly above nominal temp.
