Transmission Sounded bad on start up
Jeep sat all day in the cold weather. I went to move it at night, so it was a cold start.
I put it in drive expecting the idle to lurch forward but it didn't move. I gave it a light tap of the gas pedal and I heard a knock and it still didn't move. So I shifted to neutral, then to park and back to Drive and then it starts to move forward but is making a grinding noise like something metallic is circling and catching on something. This noise lasts for 5 seconds, goes away, and the transmission is back to normal.
I changed the fluid 25,000 miles ago (3 years ago), 12 quarts over 500 miles. The transmission always is great so I am not sure what it could be. I am thinking cold weather, cold fluid messing with pressure? I am no expert here, so any suggestions are appreciated.
I haven't tried it yet this morning, so I don't know if it will repeat.

12 quarts over 500 miles is my short way of saying I did 3 fluid changes in the span of about 500 miles of driving, since the system carries 12 quarts and every drain and fill only does 4 quarts at a time.

I would suspect the torque converter trying to fill back up with thick fluid. I have not had this happen on these yet but I have had it happen on other makes. And it can sound god awful...

Any moisture?
Rain or snow?
I've had my brake pads/shoes freeze to the rotor/drum and give a weird reaction like that.

Depending on tire size 5 seconds would be just about one full revolution I think. And it would probably take a full revolution to clear it all off.

Mr Cruiser deserves the credit Sir. I would have not thought of this possibility. Even though I am in Arizona too I am a flatlander and he is a highlander. lol
If it happens again you will probably recognize it as feeling similar to power braking.
