The "Check Trans" light did come on once.

I actually finished the towing to hwhere I was headed after noticing the problem before doing anything about it. I was almost there where I first noticed it. This was after about 4 hrs of towing.

The next day I got in it to drive about 7-8miles and the symptoms were the same or worse with the tranny cooled off and w/o towing anything. About 5 miles down the road the "check trans" light came on for the first time.

I went a few more miles to get where I was going, then added the quart of fluid before moving it again. That helped a lot.

I'm not sure if the check trans light means low fluid or overheated or possibly either. It never came on during the long towing trip, and it seems hard to believe it over-heated in five miles w/o towing.

Either way, it sure seems like the light should have come on the previous day while I was towing. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
