Did you have diaqueen or BG in it? Was it recently rebuilt? If there were no abnormal amounts of metal particles or fluid that was neglected and abused then its probably just one brands fluid color mixing in with a previous one before that. I also asked about whether or not it was recently rebuilt because if the trans gears have a similar phosphate coating when new like diff gears, then the first few fluid changes can have that greyish color due to the coating coming off.

 

that doesn't seem good!!
my trans was grayish and my tcase was brown clear

 

concluded to be leftovers from redline, fortunately.

 

Always takes a while to get old fluid out. As long as the fluid doesn't sparkle like your panning for gold

 

Although you will get some metal from synchros, a little

 

No there was no metal that came out and there was no whining coming from it. I was told that the seals in the inside might have came apart and fluids mixed and cause the pink milky fluid.

 

I use 2 qts mt90 and one light weight shock proof, always comes out blue with a hint of silver....I kick the snots outta my car so im not really worried about it. lol

 

Well I think I might just slap it back on and see what happens.
