so I have been hearing some strange grinding kinda sound randomly coming from what i think is my transmission so I went to check the mounts underneath, the mounts were there but there is a bolt missing on the bottom (if youre looking at it) right side. it looks like its something like the bolt that you take out to change the oil but its on the tranny i put some pictures on with this post. in the first picture it is a close up picture of it the second one it is in the back left kinda blurry, on the right is the oil pan

 

That is the boss for the torque arm support. There should be an arm that runs from up on the sides of the engine block down to the boss on the transmission dust shield on either side of the motor.

 

well the support and dust shield are still there so I am not really following.. sorry I'm kinda new to this all

 

As I said, there is supposed to be one on both sides. The first picture you attached shows the passenger side torque rod still attached to the boss. The same thing should be on the driver side.

 

basically in my opinion its not really that important. i dont have those on my s10 or any of my fullsizes. id say if you had it laying around put it back on but no need to go crazy looking for one unless your gonna be racing or doing heavy offroading, your transmission isnt going to fall off or anything
