My car started losing power and taking long time to shift gears. I noticed one day that my transmission vent tube had popped off. Where do I hook it back up to and does anyone thinks this is the reason why my car drove sluggish?

The vent tube connects to the transmission and then to nothing. The case vents to the atmosphere.

The sluggish problem could be a plugged catalytic converter. Here is a guide so you can confirm the failure.
