with just a little humor thrown in for fun, the first thing to look at would be a factory service manual. :lol:

seriously, the 93 fsm is the best asset for working on the automatics in these cars. there is a comprehensive diagnostic section, a flow chart, troubleshooting guide, and a repair section that has it all.

typically, you would find in a case like yours a safety neutral switch stack misalignment or a failing electronic transmission control unit (atcu.) there are 2 shift solenoids mounted to the pump body underneath the pan and a screen type filter that needs serviced. sometimes a fluid and filter change snaps a balky transmission out of it's problem.

it's not uncommon to find the transmission cooler section of an old radiator partially clogged which hampers flow (and pressure.) it's not out of the ordinary on an old car to have a stretched shift cable which has put the big switch on the top front out of adjustment. less often it can be broken wires in the harness.

it's repairable. :wink:

The 2 solenoids in the trans are the most common failure point by far. I've done a lot of them.

you will find the white 2 conductor oval cannector in the engine bay on the left side that has a harness that disappears into the transmission. that is the shift solenoid connector.

unplug that from the harness and you will see the 2 pins. each one is a shift solenoid.

rig a wire to the positive terminal of the battery that will reach the solenoid connector. touch each pin independently and listen carefully for the click of the the solenoid attached to each pin.

you may have to get someone else to listen or use a stethescope of some sort. if you do this check while the trans oil pan is off you can hear the click really well.

the solenoids are grounded through the transmission so you only need the live wire to get them to operate.
