Try engaging the tranny in neutral and see if the rumble is still there as it would be with an engine mount. If it goes away I would think you could have some torque shudder. You can do a drain and refill 3x's to "try" to eliminate the problem. If the problem persist I would recommend a high friction modifier additive (4 ounce at a time) or lucas tranny treatment (use 14 ounce at a time).
