Kohler Coralais shower leaking - what parts do I need - special tools?

I have a Kohler shower faucet. It looks like this one:
Kohler K-15140 Coralais(R) Shower Faucet with Acrylic Handle, Nonpressure-Balancing without Screwdriver Stops

The shower head is dripping every so often.
Do I need to replace the cartridge? Other parts as well?
Also, do I need a special puller tool?

What is the difference between the ceramic and non-ceramic valve kit? Besides the obvious?
Kohler KRGP30413 Coralais Valve Kit (ceramic)
Kohler GP30413 Coralais Valve Kit ("regular")?

Go with ceramic if its updated from the old washer /O ring type...

I have been out of the faucet repair for a while so that's new to me that there are two types....

So, I replaced the valve kit. However, the shower is still dripping. What else can I check?

Anybody? Do I need to take out the entire valve body?

Did you change the balance spool? Black piece...

I would have to check again. But unfortunately I think I have the "non pressure balancing model" that doesn't have a balance spool if I am not mistaken.

Checked again, It looks like I DO have the pressure balancing unit. There are two screws in the front.
Is this the replacement part: GP500520? Should I get other parts while I am at it? e.g. does it come with O-rings?

Is this a service or warranty part?

Dont know if thats the part #. There should be a part # on the spool..

You could call kohler if you like. They may send you the part at no charge...

This is the reason I dislike kohler. Some of the parts are well over $200 bucks to replace...

This is why I always put in moen..

The unit should come with all o rings..

When you remove the old make sure the o ring/washers are not stuck inside the body when you remove the spool. This happens sometimes...

So, I removed the to screws that hold the cup with the valve. However, the assembly doesn't come off the valve body. I am assuming that I don't have to remove the valve in the cup.
Is this just corroded?
