Yes. Put a jack under the motor and remove 3 bolts from side of engine and the long center pivot bolt in mount and the 2 bolts that go top down into the frame and loosen the 2 bolts below mount. Jack up the motor until you can separate the mount, leaving the engine side in and removing the frame side. The engine side can be moved out of the way without completely removing.

The code PO742 indicates the torque converter clutch is stuck on.
The torque converter is what connects the engine to the transmission.
It engages and disengages according to signals from the pcm, to aid in
smooth shifting. There are a couple of things you can try. make sure trans. fluid is full, if thats ok check the 20 pin connector, located on left
side of car on top of transmission bell housing. Make sure there's no
corrosion or bent pins. If this clears the code your all set, if not you may
want to ask your mechanic and see what he/she recomends.
Hope this helps.

If your talking about the relay switch to your air conditioner. These are usually located under the hood, behind the engine and against the center rear upper firewall, in the fuse center. You have to remove the large black plastic insulator (that spans the length of the firewall), that covers the windshield wiper motor and other components, to expose the fuse center.
Pop the fuse center cover off and read the diagram inside, so you know which relay switch goes to the A/C unit.
Should you not find the relay in the engine compartment I recommend the following.
I own a 91 Park Avenue (same body style) and on many of these modules, there are additional relays behind the glove box. This is bit tricky to get to though. Because you need a Torq/star screw driver, and you will need to remove the glove comparment to get at them.
As always be sure you disconnect the negative cable from the battery before pulling any relays, to avoid shorting out your electrical system.
