keeping aluminum transmission looking good
How do you make a 4 spd aluminum housing look new and then keep it looking new?

Either glass bead it and clear coat it, or paint it cast alumunum silver. I would much rather bead and clear, but ended up painting my automatic. Just couldn't get it to look new and get rid of all of the black staining .You'd never know it if i didn't point it out. I used the Seymour cast paint.

Looking Good
Hello, Try the product "Sharkhide Metal Protectant". I have used this product on transmissions, intake manifolds, suspension parts and various other parts exposed to the elements. I have several friends who also use it on auto and marine restorations with great and lasting results.

Aluminum paint
Krylon used to make a spray paint (rattle can) called: 'Dull Aluminum'. Had a nice finish that didn't rub off on your hand. Don't know if they still make it, though.

Keeping aluminum transmission
Krylon Dull Aluminum is still available. I second what Cardo suggested with the following additional comments: after you glass bead the case, side cover, tail extension, etc. spray them all with aluminum wheel cleaner, then hose them off thoroughly and blow them dry. I wait until the trans is reassembled to clear coat it. Even with the clear coat the surfaces are often pretty rough so grime easily attaches to surfaces so you have to not let it get too far gone so heavy duty cleaning products/processes are not needed.

I also agree with Cardo. Did mine that way in 1990. Every spring I wipe it down with some brand of metal prep in a rattle can. Still looks great.

Two options: Have it bead blasted and clearcoat with Sharkhide or paint it with Duplicolor Cast Aluminum or Rustoleum Stainless Steel Paint (slightly deeper color but works great). After the color is dry, mist it with Duplicolor Metal Specs silver. The metal specs add a metallic highlight like you get from freshly bead blasted aluminum (like a brand new Edelbrock intake manifold). The aluminum part looks more authentic rather than just painted dull silver.
Here's my intake painted this way:

NAPA sells a product called aluminum brightener. I've used it on motorcycle engine cases and it worked well to remove dirt, grease and stains. Spray it on, scrub with a brush and rinse with water. It is an acid so you need to take precautions and wear PPE. https://www.napaonline.com/en/p/MCR1458
