I'm a fairly new 97 J30 owner and brand new to this forum (so much great stuff here)
I am having some "hard shift " issues. I found and tried the a/t self diag flash test but couldn't get the light to flash at all. it will come on for two secs when i turn the ignition to on but does not flash after i follow the rest of the procedure.
Does this procedure not work with the obd2 models? or is there some other issue?

Is the hard shift just from 1-2? Does the shifting occur normally (like in the RPM range based on throttle input), or are the shifts also erratic?

1-2 is most noticeable and does seem to vary with acceleration
the remaining shifts not nearly as hard
from what i've read it sounds like the a/t self diagnostic would be most helpful, just don't know why it won't work
took it to the local parts store and had the codes read, shows ratio faults in all gears
