well, I dropped the pan, pulled both shift solenoids, both ohm out
good and both worked fine at 7.5 volts as advertised, replaced
filter and fluid, codes gone, shifts fine, all OK, So I give as to
why it was coding, but it had 2-3 gears only before, now it's
fine, fluid not bubbly, flushed it out again and hope it stays
fixed. I also checked wiring between trans and pcm.
