Vibration while stopped in drive Options

[mimicit]

I have a 96 St AT. When I am in drive with the breaks applied, I get vibration in the steering wheel. It's not real bad, but I notice it.

I just replaced the drivers side CV and dumped some AT fluid out when I pulled it. I Checked the levels and it reads good for HOT, that was a little weird as I expected to have to add more.

I have been driving around this weekend testing the new CV, and the vibration is really noticeable now.

I put it in neutral and it goes away. Every other gear including reverse vibrates. Park does not.

I ran a search for this symptom before I posted, and this is my first post, so hi!

Awesome suggestions, really active community, you guys rock.

My thought is once the car is put in gear, there is a load placed on the engine from the transmission. Once that transfer of energy to drive the transmission happens, the motor has to work a bit harder and that is translated into vibration. I would suspect it could be resonance from the transmission at that specific idle level, so changing the idle might work. It would change the frequency of the coupling between the engine and the transmission. I also think engine mounts would work as well. More then likely a combination of the two.

I don't have a lot of experience with working on cars, and changing out the engine mounts seems tough. I would imagine I need a hoist to hold the engine up when I changed the mounts? I have a manual but it does not go into detail.

Could anyone give me a high level breakdown of what I will need to do this?
