Kind of strange fluid level in tansmission

[Pat Martone]

I will share a "strange fluid" in transmission story. On one occasion, I must have pumped too much grease into the U-joint, and later learned that some of that grease found its way into the transmission. I discovered this when I drained to change the transmission fluid and it had a red greasy color to it and it was quite thick and took a long time to drain, which I believe came from the red grease that I used to the U-joint mixing with the transmission fluid. Is this a unique problem, and is it something to worry about? I welcome comments. Thanks.
