motor/tranny mounts, '92 SSE s/c
 

I just discovered that the front driver's side motor (tranny) mount has separated where the rubber meets the metal bracket nearest to the engine.

How many motor mounts does my engine have?
Do they just bolt-on?
Can anyone tell me the part numbers, cost, and how to replace them?

I doubt that I need to replace the upper torque mount on the passenger side, that one looks ok, but I couldn't even see where the other mounts are. I want to replace all but the torque mounst as soon as possible, but only if they need replacement.

I just called a couple of auto parts stores, and they said there are 4 mounts. There's
the rubber torque axis mount and the lower fluid mount on the passenger side, and 2 tranny mounts on the driver's side - the lower front rubber one (mine's bad) plus the lower rear fluid one.

How can I tell if the fluid mounts need to be replaced? Is it common for only the front driver's side tranny mount to fail? Have any of you been through this with your Bonnie?

Problem solved.
I called around, including a local Pontiac dealership. The dealer wanted over $300 for the rear tranny mount (driver's side) so I didn't buy anything from them.
I bought only the front left tranny mount (driver's side) from auto zone for $39 and had it installed at a local tranny shop. It was completely broken where the rubber meets the metal on the tranny side of the mount. They checked the other tranny mount and the 2 engine mounts and they were all ok.

Interesting note, though - Auto Zone, Kragen, Pep Boys and the Pontiac dealer said that the rear engine mount (passenger side) and rear tranny mount (driver's side) were fluid filled or something like that...but according to the tranny shop they're not...so everyone I called was wrong about those parts.
