Default Orange silicone normal on T56?

Question: Is orange silicone like this normal on a T56 or has my transmission been tinkered with? The tail housing looks similar.




Orange silicone squeezed out of front housing on T56

Nope....someone's been there. I think the factory uses gray.

Wonderful. Bought the car with 140k or so back in 08 and didn't even get a virgin. Now I wonder how many of the transmission problems are poor assembly.

I was planning to refresh it myself. Would someone else's tinkering make this a worse idea or will a proper rebuild manual give me enough guidance to return it to factory spec anyway?

It may be a quality rebuild and the problems developed over time, cant hurt to open it up and check it out.

Yup depends on what's in there and what your problems are. Even a quality upgrade build driven by a potato will get damaged over time.

It may be anaerobic sealant which is used by GM and high quality builders. Hard to say since I can't touch it. It's normally used on manuals trans and transfer cases.
But that looks a little too orange for me. Anaerobic is reddish orange. more-so red. If it's very orange, then yes, someone has been in it and used some regular RTV stuff.
