Well, I was able to decipher what you were saying even though there wasn't a period anywhere in your post. (IMG:style_emoticons/default/blink.gif) Dr. Evil will kill me for saying this, but I used a couple cans of brake cleaner. A lot of guys don't believe in this because it strips away the original coating that was on the transmission to protect it. After I got mine clean I repainted it silver though, just in case. Good luck!

If you get it clean and want to paint it, I recommend Aluma Blast from Eastwood. I'm doing my Alfa trans with it and it looks great.

I put a little heat to mine with a torch and it melted off like butter.

I put my kids to work srcapping at mine, after a couple days and a new coat of silver paint it looked pretty good.

I use AWSOME from the $ store! It works great!

spray on and let it sit for 10-15 minutes, use a wire brush and a screw driver to loosen the tough stuff and spray more on. Let it sit for a few more minutes and hose it off! If you have a pressure washer even better!

Repeat until clean! 2 - 3 times should be enough!

Brake cleaner is fine. Water is not if it gets inside. I use the Awesome that Jeff speaks of since he posted about it a while ago. Ez-off was my old go to, but Awesome is too cheap and easy not to use.

There are a lot of harsh cleaners that will do the job. But as many others have said, a little heat goes a long way. While I am not willing to use a torch on mine, warming the trans with an electric heater or heat gun will help a lot. Also any water based cleaner will work better when warm.

Just be careful about trying different cleaners one after another and creating a situation where you are mixing chemicals. So bad and dangerous things happen when chemicals are mixed. Fully rinse one cleaner before trying a new one.

As for protection after cleaning, mine was coated with Cosmoline. www.cosmolinedirect.com ... Pretty sure it's close to what the 901 tranny came with from the factory. Richard Casto at Blue Sky Motorsports did mine. I'm sure he can talk to the specifics.

The factory coating sucked! It does not last the life of the gear box, it is gone after a few years. I wont use it. There is better stuff out there that lasts much longer.

You guys are great thanks! I had no idea that the case was coated with anything other than engine oil and road dust!

Before I get corrected, Rich used something that was "Cosmoline like" I think. (IMG:style_emoticons/default/unsure.gif)

Anyway, what do you use then Evil?

I used that Awesome at the Disco Bay tranny clinic, Jeff gave me a spray bottle full!. sprayed it on, drove the shell to the car wash (guts removed) and pressure washed it, looked great! Jeff gave me a spray bottle full!

I am by no means authority, but it is my understanding that the transmission case is magnesium. based on that assumption cleaning it with whatever not corrosive means is fine, but once that is done, it needs to be painted or otherwise coated. mag oxidises and becomes brittle in no time if not protected from the atmosphere. on my matchless g50 the cases and hubs were mag and had an aluminized gold paint that was on any of the magnesium parts. it used to turn green overnight without a barrier.

I would guess it is more of a east coast thing because of the salt on the roads!

I have not had any problems here in central california!

There is at least one thread that covers this ad nauseum. Check them out (IMG:style_emoticons/default/smile.gif)
