TF-999 Transmission

So I found out what transmission I have.. but while I was out there checking I noticed a flat gray liquid on the bottom of the transmission bolt and the bottom of the transmission what could this be?

9 times out of 10 I find it's engine oil that has dripped down the block and onto the trans on it's way to the road. And it does change color on the way down mixing with all the dirt and stuff.

I would say check the condition of your fluids (so you know one of them is not contaminated) and then wash the engine and trans, that way you can identify where the drip is coming from when it comes back.

I use the Black Magic Engine Cleaner, it says it's safe for electronics. So I just put a bag over the carb and spray down the engine with the cleaner, let it sit for a min per the instructions, and then hose off. Been doing it for years without a problem. Makes everything look nice under the hood
