Transmission shakes when I hammer it. AOD-E...help

[Road_Runna]

I recentlly took it to a mechanic, because I was having problems with a leak in my tranmission. Anyways, they said a couple of bolts where loose (I don't think they where pan bolts) and that's why my transmission was leaking oil, so they tighted those bolts.

Now I noticed shaking under the car (not the wheel, but my dash, stereo, etc) while I was racing tonight. Like I said, when I hammer it around 4K, or 5K rpms it starts shaking. This has happened on more than one ocassion just tonight.

Should I be worried ? I also checked for any leaks (tranny), and found none.

I'd rather mod the engine, thean buy a new tranny, so that's why I came here.

You sure it's the transmission shaking? What kind of shape is your harmonic balancer in?

Well my car only has 69K miles on it. What should I be looking for, when checking that balancer ?

see if the rubber is loose, also check you tranmission mount/ engine mounts.

Yea, what 95YellowGTbeasT said. When checking the motor mounts, check for visible cracks. Do the same with the transmission mount.
