Early this morning, a friend came to help me with the cleaning of the gearbox. I knew it was not an easy task, but decided to give it a go.
So here are some before showing the general state of the GETRAG box.









Not too much grease and dirt, but it had some heavy embedded pitting on the alloy-magnesium casing.
Our Weapons:

Household cleaners, Various brushes and sponges, old trusty Wheel Brightener, CG All Clean, Meg's APC, Valet Pro Citrus Tar and glue remover, wire wool and some cheap-o-mf-towels.
At first we decided to try Valet Pro Citrus tar and glue remover:



Excellent results on baked on tranny oil, I have to admitt.
We pre-soaked the whole gearbox with Meg's APC and rinsed.

Attacking the inner casing with various sponges, wire wool and all of our available cleaners



After the inner casing was cleaned we attacked the exterior. This was a very time consuming procedure sadly






After 3 hours under the hot sun, it was time to bring the tranny inside the cool shade, and have some relaxing time.

As for the side caps - looking tired before

But looking almost perfect now

After the long degreasing session, we stumbled across some weird pitting.

Metal polish and a wool polishing ball was the weapon of choice.

Unfortunatelly, we couldn't get all the pitting out even after three sets of polishing. Any ideas on how to remove those stains? Soda blasting might work.
So here are our final shots, after lots of fun and very dirty palms.









The end result isn't satisfactory in my eyes but I dont want to paint it for the moment, and leave it be at stock appearance.
Cheers
