truck shakes at a stop while in gear (auto tranny)

[mtbdavid]

Hi,
I have a 4 cylinder 96 4Runner with automatic tranny. When at a stop and in Drive, 1st or 2nd gear the truck shakes. When I put the truck into neutral or park the shaking, vibrating stops. Any ideas what the problem could be? Bye the way, the car does not shake or vibrate when moving in gear, only at a stop.
Thanks,
David
