V1 F35 Transmission leak help

[Stingray]

Gents, I could use some help. I've got a leak in my transmission and I think it's behind the flywheel. The oil doesn't look red so I'm assuming it's engine oil.
My plan is to remove clutch and flywheel but before I do does anyone know what seal part number behind the flywheel I should replace? Is that a rear main seal?? Is there something else that can be leaking oil? I think the clutch bolts where the type that you can tighten once so I assume I'll need new clutch bolts. It's a new clutch and flywheel, is the clutch still good if engine oil got on it or can I spray it with a bI appreciate any advice. Thanks in advance!!!

The only sources for fluid leaks inside the bellhousing would be clutch hydraulic fluid, oil from the rear main seal (ACDELCO 710237 or similar), or transmission fluid via one of the two seals on the clutch hydraulic slave cylinder. With all the clutch dust in the bellhousing, it's very easy for clutch fluid or transmission fluid to look dark. Try putting some on a sheet of white paper and see if you get any new color that shows up as it soaks into the paper and spreads out.

I would think it's less likely for engine oil to contaminate the disc friction surfaces than either of the other two options. I'm not sure whether contamination would be visible before the friction surfaces are compromised, or if it'd start slipping without being able to see fluid on it. I don't think brake clean will pull fluid out of the friction material. Others may have input on how to do any cleaning, if at all possible.

Worst case scenario is you put it all back together and find the clutch slips, so you take it all back apart to replace the disc only.

Looking at your first picture, though, it kind of looks like everything is wet from the slave cylinder down, which might mean it's not engine oil. I don't think that's the pattern of wetness you'd get from a leaky rear main, but then again, I've not seen what it would look like on an Ecotec.

You really need to determine what the fluid IS! There is a seal on the trans main shaft, I believe, on the F35 it is on the T/O bearing it's self. Is the back oh the flywheel look like a County Fair spin painting, many oily lines radiating from the flywheel bolt flange.
