I'm the proud new owner of a 1993 YJ wrangler (After owning an XJ and ZJ). 4.0, TF999 auto 3spd.
I drove it home with a transmission leak and immediately dropped the pan. The fluid was a milky pink, indicating that its contaminated with water. No greenish hue.
Changed the fluid, refilled, and on my way. Planned to drop it again this week and replace again, and once more soon down the road.
I was missing the dip stick, which I picked up today. Went to check the fluid level, and found that the fluid is still a very white pinkish color. I know that the pan only has half the fluid or so, and that I can should expect contamination, but there is very little if any change in the color since the first swap.
My next step is to think that I'm getting my water contamination from the tranmission cooler in the radiator. There is no visible oil in the coolant (at least, that I can see by pulling the radiator cap).
