there should be a diagram for the belt somewhere under the hood of your car usually adjacent to the emission (VECI) label near the rad the belt or on the actual hood
the tensioner is automatic adjusting. using a ratchet and the proper size socket rotate the tensioner (usually anticlockwise but youll be able to tell as you turn it) to release tension and slip the belt off of the alternator pulley. be careful not to let go of the tensioner while slipping the belt off or you will hurt your fingers!
Something is drawing to much power you need to check a few things what the fuse is and is it the correct amp fuse cause if I was blown and someone has up the fuse rating it will get hot but could melt the wiring loom even set on fire don't put a stronger fuse in anything
buy the FSM , read the trans pages.
yes, on many cars the trans solenoids can be changed
pan off. and is easy, (ever drop a pan before?, no, then not easy)
Some trans the the solenoids are above the valve body.
why not buy the FSM and read the chapter. and avoid making it all worse , by skipping steps or getting dirt inside.
the A/T is the most complex part of any car, bar none.
we do the chapter on on car checks, and if bad , tranny its sent out to a pro tranny shop. (even the dealer does that now)
this saves the training costs at the dealer big time. (long schools)
try to use google and utube to get a feel of the complexty here.

More than likely the spring inside the latch has come undone. To save some money you can remove the latch from the trunk, open the latch and reset the spring. To Remove the latch you will need to remove the carpeted cover on the trunk lid (there are about 10-15 phillips screws holding it on.) Once the cover is off disconnect the rod going to the latch by opening up the clip thats connected to the actuator. Disconnect the wire harness, Remove the 2 10mm Nuts holding the latch to the lid. Remove the black plastic cover on the latch and remove the electrical piece (the plastic cover wraps over the latch and is secured buy 2 plastic pressure snaps). Look down into the latch and you should see a small spring...on my Jetta the spring wasn't connected. take a small pointed object ( I used a light tester) and reattch the spring to the black hook. Mine had some broken plastic in it and After I removed that it worked fine. Once the spring is back into place reassemble the trunk and you should be good to go. No money spent, and it only takes about a half hour or 45 mins to do.
