line is completely separate from the coolant so the overflowing there cant be from engine oil cooler. the trans cooler is a part of the radiator so if there is a failure there tranny fluid can go into the coolant. it would be pink then.

the rough running when hot, well, maybe it is running roughly all the time and is being masked by the warmup timing on the injection. idle too low? air in the lines?

does the mount move around like you first described still? are all the bolts in the mount?

the shocks can be changed wo jacking up anything. dont think they are the problem though.
