Bad motor mount or bad transmission mount? W201 190E

I know one of them is bad. At idle the car is relatively smooth, close to what I would expect but as soon as a gear is engaged you can tell something is rattling.

I visually inspected the motor mounts, they look OK, I can see the right front well, no obvious sign of failure in fact it looks pretty good, can't see left side as well but again, no obvious signs.

I am guessing that a transmission mount is possibly the culprit, one because previous motor mount probs, the engine shook even when it wasn't in gear and b, while the transmission shifts smoothly, I occasionally here a clunk when shifting INTO gear. Doesn't happen all the time so makes me think the trans is moving around on a faulty mount.

Thanks for the sounding board, if anyone can concur that would be great.
