Correct Color for Spyder Tranny & Dif
Posted by: RKF ()
Date: January 14, 2020 02:43AM

I will soon be hauling the transmission and differential assemblies,from my '63 Spyder, to the Corvair Ranch for a rebuild.

Currently, the units are painted red, but I don't know if this is a factory color or if they got painted that color somewhere along the way.

What, if any, color is correct for the tranny and dif?

I would say satin or flat black if anything. I've always wanted to try paint that's supposed to look like cast iron for master cylinders.

Transmissions and differentials came unpainted from the factory, I believe - raw cast iron (or aluminum, in the case of the PG).

I believe the ones in the cars came raw and un-painted. Crawford Rose has had some NOS early transmissions that were raw and we have 2 NOS 64-65 transmissions- 1 still in the box and they are both painted.

I have a GM REMAN differential for a PG EM. It is black (and has an interesting looking paper tag with info on who did the reman?).

The transmission and differential in my '65 were bare cast iron and to the best of my knowledge always were with the exception of the white paint across the code number on the differential.

While going through the car and cleaning things up, I decided to paint both the differential and transmission as a personal preference.

I went with a Cast Iron color for the differential and left the face of the differential which will be covered by the bell housing un-painted and taped around the white paint where the differential code is stamped so it could remain easily visible. I went with Satin Black for the top cover and have since painted the Yokes a Satin Black color as well so those who might ever look close, can see that I didn't just spray bomb the entire unit while together.

I went with a Cast Aluminum color for the transmission to give the "Aluminum" appearance. I left the end cover bare aluminum. I also left the machined ends of the transmission and differential bare where the gasket surfaces are, again as a personal preference and to illustrate that things were disassembled before paint.

Catabolic, looks really nice. Going to try to do something similar to mine. Is it OK to sandblast the cast iron transmission and differential cases?

If you sandblast tape off all the openings to keep from getting sand inside. A lot of people (me included) won't risk it. Sand bad.

There are different makers of cast iron color paint. Some look perfect, others are just grey paint. Have to hunt around.
When I built for concourse I had a brand that was perfect and wouldn't melt if oil got on it. They are gone now because we are saving the earth!
I also used this for tie-rod ends, steering arms and steering box's. Anything that was bare cast iron.
If you want the clean factory new look, I recommend a finish like this.

For painting cases that aren't being rebuilt I clean them good and then use mixes of POR-15 black and silver. Mix in different ratios for different shades of steel/cast appearance.

I would advise against sand blasting the case, especially if it still has the internals intact. Sand gets in some of the most difficult to remove places and has a tendency (as I hear it) to stay put until the most inopportune time, like when everything is back together and all seems well.

I have heard tales of people sandblasting engine blocks and living to deeply regret that choice, even those who would swear that all the granules were flushed out.

I left mine intact, drained the fluids from them, split them apart then carefully cleaned them individually in my parts washer. Once that was accomplished, I cleaned the surfaces with Brakeleen then again with Lacquer Thinner so I would potentially have a relatively clean surface for the paint to adhere to. I guess time will tell.

Did my Corsa in "cast aluminum" for the tranny and semi gloss black for the diff, with the tranny side cover also black.
