This morning after I started my Excursion V10 with 4R100 and pulled it out of the garage, the 'off' light on the shift lever started blinking on and off. I know this is not a good thing! The last couple of weeks, I noticed that it didn't shift into OD as readily as it should have, and suspected that something wasn't right. I checked the fluid, and it's not burned, and is on the full mark. I've got 28k on it, and am probably due to have it changed, but I don't think it's overdue.

I had a 46RE go bad on a '97 Dodge Ram with 18k on it. I don't think I'm hard on my trannys. This is starting to give me a complex!

(I posted this on the transmission forum also, but I thought maybe one of you guys may have some experience with this!)

Nice truck, don't chance it. Go see your dealer (or favorite mechanic). As for your fluid, 30K changes recommended. Good luck.
