2001 solara clutch issues??

So I got into my car this morning to go
somewhere and when I started it up it was
making a rattling sound coming from the
passenger side under the hood can I put it in
gear and started to go down the road and the
rattling sound got worse so I kept going and all
of the sudden the car like jerked almost to a
stop then when I tried to put it back into gear it
acted like it was binding up and wouldn't go
forward I had to put the gas pedal to the floor to
get it to us off the road. This all started I'm
assuming about a week prior when in second
gear it would make a humming noise then the
other day on my way home it kept popping out
of third gear can anybody help me out with this
