Not likely to be the clutch pack as you dont mention slipping wich is the normal sign of overheated or worn clutch bands.Not sure with your vehicle but 2 methods that control the shift severity are engine vacuum or pump pressure inside the auto. so check balls are a possibility. They are spring loaded to open at a set pressure,or close.Could you check to see if its a vacuum controled and if so its a lot easier to fix as the vacuum control should be outside the trans.

Definetly your slave cylinder. Seen it several times on toyotas in my career. I do suggest buying a new slave cylinder rather than trying a rebuild kit. I've had customers that requested a simple rebuild kit in the past, and had them fail within a few months. I know my guys, and I personally rebuilt them correctly, but they still failed. I've never had a customer return with a complaint on a new one. The repair itself is very simple, and if you buy a new one, you should be fine for a good long time.

I hope this helps you, and I wish you luck on your repair.

Bring the vehicle into the dealer if you have a sticky gas pedal. This is a TOYOTA PROBLEM.
Door handle:
It easy ! You need a philips and flat screw driver,and a needle nose pliar.
Use flat screw driver and pry out the two or three dust covers for the arm rest screws then use philips and remove the screws. Next use the flat screw driver and pry out the black plastic mirror cover from the inside of the door. Pry out the switch with the flat screw driver and disconnect it. On the side of the door panel just above the striker/loch mechanism is this plastic push pull type of a hold in screw. Use flat screw driver to get it to move a little then pull it out with the needle nose. Depending on which door your doing if you have a map folder in the door there are two more screw to remove on the bottom of the door.
Now the inside door handle is tricky it comes out in TWO pieces. Use philips and get the only hold down screw you see out.( you may have to pry out a little screw cover first) Now the inside door handle cover is removed by placeing the flat screw driver on the rear of the outside of the cover top and on the outside rear bottom to release the tangs that are holding it onto the panel.Pry it out lightly you may have to place the screw driver over the top of the door release button and pry that way. Don't loose your cool its a pain but it will fall out. Once its removed unhook the panel.

Next lift the plastic cover and remove the door handle hooks and levers . Basically use common sense this is easy stuff. There may be two screws from inside of door panel that keep handle in place . Then work handle loose from outside and inside . reverse for installation.
