The wider band is a great upgrade when used with a new drum.I prefer the carbon lined band instead of the red. Borg Warner,Raybestos and Alto are all good friction plates.Kolene steels are more expensive than plain steels.Are they any better? Again personal preference.Your not rebuilding a trans for racing, so don’t over think it,you’ll never stop buying parts.
4L60e trans. Rebuild.

Pretty much just want one that’ll be stronger and not wear out as fast.

Also I would like for you guys to look at the notches on this gear. Does it look like they are worn into the teeth or are they manufactured there to sit in a certain place l?

The notches are factory. In the first pic you posted on the right side of the first few teeth on the left I see a wear mark or a shadow. Take a small screwdriver and run it up the sides of those teeth and make sure there is no step.
If they are smooth all the way up,reuse it.

Photos kinda show wear on the teeth at the ring gear and shaft. Check the ring gear snap ring groove area. Crud likes to build up there.
Ignore the rough aluminum drum. Most of them look like that.
I suggest a kit to over size the AFL valve assembly in the valve body. Its always worn in a high mileage 4L60E and can cause main line pressure problems. It requires a reamer tool to fit the brand of kit you buy. Sonnax has an AFL 4L60E kit, TransGO also has a kit. TransGO kit is much easier to use and install. I used hundreds of them over the years. Lube the snot on the reamer tool if you do that. Usualy you can use a pick tool and check the AFL valve wear as it is still in the valve body. They wear a lot since that valve is always moving a bit. For those reading and wondering about this: the 4L80E suffers with AFL wear too..
TransGo AFL kit comes with or without the reamer tool. You need the reamer. Both kits are a bit pricey. Sonnax is more $$ than the TransGO kit.
If a corvette servo is installed and a concern on ruff shifts? Do not enlarge the shift feed holes in the separator plate. If you replace the OEM boost valve , stay with the same diameter size of boost valve. Boost valves wear out in high mileage too. You can have the advantage of larger servo surface apply with corvette type servo , not the harsh shift.
A wide band for 2-4 gears must have a flat drum surface as mentioned. Always check the drum for level surface with a straight edge. Check a new too. If you reuse the drum , scuff the surface with 320 grit wet... NOT cross wise, scuff in the direction the band rides. Dull surface is good, not ruff surface
If you tow stuff, I suggest the Sonnax billet over drive servo. I have used them for over 200k miles on my own vehicles

Typically these performance rebuild kits replace the items that the stock 700R4 through 4L60E’s are known to be inadequate for heavy duty and performance work.

How bad does this look to y’all? When I put it back in the valve body it doesn’t exactly want to slide back and forth very smooth or easily. The others slide back and forth pretty smooth and easily. Worth replacing or is there enough pressure while it’s running for it to not matter?

Also what does anyone think about this separator plate with the smaller shift feed holes?
