Just pulled the cover on my '95 8.25 and there is the glitter of metal shaving and the fluid has bubbles in it. Has the fluid been contaminated? Fill/reseal and all should be fine? Should i be concerned. I pulled the cover because things have felt a little off back there (small shimmy). I thought I would just pull the cover, check to make sure everything was OK and refill the fluid but now that i see this im worried.
