I have a broken drive motor mount,first I can't seem to find the part,second,I have no clue how to fix it.Most detailed answer will get the 10.

U can pop the hood have someone put car from park to reverse then back to park and see if you can get enough movement that way or take pry bar near all mounts one at a time wiggle engine you can almost always tell a worn or broken mount.

these cars tend to break the front transmission mount which is located on the drivers side near the radiator on the front rail of the engine cradle (front sub-frame). when this mount breaks the engine jumps on accel in drive. to change it you will need a floor jack, a block of wood and a good set of hand tools. support the trans under the pan at a corner, not in the middle of the pan and just raise the jack enough to support the trans. unbolt the mount from the trans and sub-frame, remove both pieces and replace with new, additional lifting of the trans will be necessary to get the new one piece mount back into position, make sure to watch the pan to make sure it's not being damaged. you should be able to get the mount at your local auto parts for $30-$40 dollars, it would be called the front transmission mount and it's in the left front position.
Professional replacement woul be about $130.00 so way your options. Hope this helps.

This is not a do-it-yourself shadetree mechanic fix. You'll need some decent knowledge and skills and tools to accomplish it. If you're lucky, you'll only have to lift the car on a hoist, unbolt the mount, lift the engine, and swap in the new mount.

Ask a decent mechanic what it would cost to repair it. You can find one at the link below, I bet. This would probably be cheaper and easier than buying the tools you'd need to do this yourself.

Any GM dealer parts department can order this part for you.
