i would caution you on who you go to. you don't want to pay $400 for a
$110 part. and you want someone who knows more than "replace the
transmission".

i would recommend you take care of the general condition things with the
motor and see what effect that has first. change the fluid on the
transmission one more time too.

mine's the 89 with the d15 motor. it has a "kickdown" cable and lockup
clutch solenoid but no shift solenoids like yours. i did have a
solenoid go bad in a way that it would trigger code on one ecu, but not
another. i figured my old ecu was bad and replaced that for $35 at my
local junk yard. as a diagnostic tool, you can try that too. you can
always sell it again if it turns out to be unnecessary.
