I have a 2000 Monte Carlo ss 3.8 engine would like replace mount how many lower engine mounts do i need and transmission mounts hydraulic
There's one under the engine on the passenger side of the engine cradle (between oil pan and crank pulley)...
...and one attached to the driver's side of the transmission that bolts to that side of the engine cradle.
If you jack up the front and pull the wheels off, you can see them from the side (may need to remove splash panel, as well).

ALL mounts sold by stores/aftermarket that are black/rubber are NOT solid, regardless of description. Only all-metal or full poly mounts are solid, but the regular $20-30 ones from any store work fine.
I made a video of DIY poly mounts last year, if you want to see me tinker with some store-bought ones. Some other videos of removal/install methods are out there, too. It'll either require lifting the engine 2-3" or dropping the cradle 2-3" to get each side out.
