yes, the older tranny has 2 wires.
one is before the pressure switch and one after.
one must read 30 ohms (+-spec) if not the coil is open.
this wire is controversial.
many cars with trailer hitch? have mods here, a hidden switch or delay box. that allows. driver to turn off lock so he can pull a tailer and not have TCC HUNT.
that hunt will drive you mad and wreck a good TCC lock.
i think the pressure switch is for cold ATF fluid, but turned out to be more trouble that cured, so in 1995 it was deleted.
just engine cleaner soaks over and over and gentle water spray, but my cause shifter cable to rust.
here is the early car, and wiring, the Relay is gone !
lt .blue must be 30 ohms (spec ohms) if not , its bad. switch for pressure or not.
no need to pull tranny yet, just that one pin,
keep in mind tranny may not be 1997, not at all after so many years.

move the white wire to the pin, that reads 10 to 30 ohms. and drive.
they might have changed the pin numbers in 1996.
are you sure the ECU in your car is the A/T ECU? last digits? dash -72E31 ( or E21 for 2wd)
and not E01 for M/T !!!
