Yes, it can be fixed. Just replace the diverter valve, not a big deal.

install new diverter stem, or rebuild old one

Diverter valves don't regulate the temp at all they are used with a standard shower valve that regulates the temp and the diverter selects the shower head/body spray/Rain head or whatever configuration you have. This valve can't be used on it's own.

I'm assuming the leak is in the wall somewhere between the on/off lever or knob and the shower head. It is a good chance that it is the mixing-valve. It could also be where the shower head screws into the drop-eared 90*. If it is the mixing valve, it is either ruined, or a bad seal that might be replaceable. If it is busted piping the wall will have to be opened up to replace it. Good chance that the arm to the shower head is leaking at the threads where it screw into the wall. Good luck.

The cartridge has 2 or 3 o-ring type seals around it that feed the water through, it picks up both hot and cold and mixes them. Some cartridges are replaced as one, some you have to replace the seals, just take the faucet info to the hardware store and match it up. I think the diverter is for the shower. It sends the water up instead of out.

you must replace the whole stem.you can get it at homedepot. first take the cover off over the stem. this should screw off or is held on with a allen key.then unscrew stem from valve body.make sure water is off to tub,just in case.

Probably has water deposit minerals build up on it. Push and or pull with pliers until freely moves,soak in Lime away solvent ,toothbrush on.

There is a threaded stem that passes through the spout and attaches to the white plastic diveter valve. If you are starting from scratch (everything apart), you can put it back together in this order:
1) Place the white plastic diverter inside the spout. the circular side with the black round washer should face the the wall side of the shower (mating up against the threads for the water pipe).
2) The stem can now be inserted from the top and into the notched section of the white plastic diverter valve. The threaded end of the stem shoud be outside of the spout (from the top side).
3) A round black washer fits over the threads. It should sit right where the threads end. Dont push it all the way on to the unthreaded portion of the stem.
4) Screw the threaded knob onto the threads.

Should be ready to install now. Including the spout itself, there are 5 parts and are configured in this order from top to bottom.
1) Female threaded knob (the knob for operating the spout)
2) Threaded stem (threads on top)
3) Round black washer
4) Spout
5) Whit plastic diverter valve.

Mine leaks when I turn on the shower, thus reducing shower pressure. I looks like a poor design to me. The stem is not a tight fit in the spout and this allows the diverter to "wobble". The washer on the diverter valve does not seat tightly and allows water to leak out the tub spout when showering. I would replace the spout.
