Just thought I'd give you guys an update....
Aftermarket balancer was installed.. cost me $270 for the part, and almost nothing for the labor.
Had the transmission completely rebuilt for $1250.
She'* running pretty good now, there'* a new rattle somewhere (I think exhaust)... but I haven't been able to track it down yet.
It'* very suttle... I can only hear in INSIDE the car... when the stereo is off.
It'* coming from the rear, but I can't hear it outside.
Anyways... just thought I'd let you all know how I made out.
