Question about 1987 Pontiac 6000
To 'Transmission Lockup'
The solenoid you are looking for is a cable running into the transmission from the engine computer. When the car reaches 35 mph, and is cruising, the computer will send a signal through the cable to the transmission to lock-up. For a shop to diagnose and repair the TCC (torque clutch solenoid), will cost about $150.00 or so.

I'm not sure if you still need help with this seeing that it is an old post. Anyway, I will do my best to help out. I did change the lock up solenoid on a 6000 once. The tranny was out of the car so I don't know if you can get the cover off while it is still in the car. (I no longer have the car). The solenoid is located behind the cover on the driver side of the transmission. If I remember correctly, it was not very hard to change (its been a while). If I remember right I believe the kit actually came with instructions, but I think you can see how to do it by looking at it. I think it was a couple screws and some connectors. Hopefully your car is fixed by now anyway, it has been a while. If not I hope this points you in the right direction. I know that this solution isn't very detailed however I think its better then nothing. Good luck

Depending on transmission,if overdrive or not, the lock up solenoid is behind left trans cover. to acess the solanoid first remove the tire and splash shield and remove the side cover. then find lock up solenoid, it is on the valve body and has two wires. it is a square silver box with two wires and is held in place with one torx headed bolt. when removing make sure you don't drop the bolt in the bottom oil pan. replace with new one and wire the new one together with posi-lock connectors. they are a wire splice connector that is near impossible to come unconnected. reverse removal procedure to finish. recommend replacing filter and gasket when doing repair. also fill up trans with fluid. dexron III. hope it helps. if not clear enough can explain further.

there's more than 1 and they are all inside the pan and in the valvebody be careful messing with this stuff it could become very costly very fast. good luck

whether it is the smaller (4R70w) or the bigger (E4OD), the solenoids are under the pan. The E4OD solenoids are in one big block where the other trans has them seperated

The automatic transmission shift lock control switch
With the ignition in the ON position, voltage is supplied to automatic transmission shift lock control switch. Voltage flows through the normally closed contacts of the automatic transmission shift lock control switch to the automatic transmission shift lock control solenoid. The automatic transmission shift lock control solenoid is permanently grounded. This energizes the automatic transmission shift lock control solenoid causing the transmission shift lever to be physically locked in the PARK position. When the brake pedal is pressed the contacts in the automatic transmission shift lock control switch open, de-energizing the automatic transmission shift lock control solenoid. This allows the shift lever to be move out of the PARK position.

The automatic transmission shift lock control switch.
The park/neutral position switch.
With the ignition in the ON position, battery positive voltage is supplied to the park/neutral position switch. When the transmission is in the PARK position the contacts in the park/neutral position switch are closed. This allows current to flow through the switch to the automatic transmission shift lock control switch. The circuit continues through the normally-closed switch to the automatic transmission shift lock control solenoid. The automatic transmission shift lock control solenoid is permanently grounded. This energizes the automatic transmission shift lock control solenoid, locking the shift linkage in the PARK position. When the driver presses the brake pedal the contacts in the automatic transmission shift lock control switch open, causing the automatic transmission shift lock control solenoid to release. This allows the shift lever to move from the PARK position.
Park Lock Solenoid
The park lock solenoid is a safety device that prevents an inadvertent shift out of PARK when the key is in the OFF position. The key must be in the RUN position to release the park lock solenoid. The system consists of the park lock solenoid. With the ignition in the ON position, voltage is supplied to the park lock solenoid. The park lock solenoid energizes through a permanent ground unlocking the shift lever. With the ignition in the OFF or ACCY position the park lock solenoid de-energizes and locks the shift lever in the park position.
Shift Lever Does Not Move with Brake Pedal Depressed
DEFINITION: Transmission shift lever will not move out of the PARK position with the ignition ON and the brake pedal pressed.
