Trans Adjustment or Problem?
My '05 CC DWR 2WD PSD started doing something strange just the other day (4500 miles). The trans used to stay in OD all the time when over 45 mph or so - as long as I was easy on the fuel. Two days ago, the trans started shifting out of OD frequently no matter what speed or mode (Tow/Haul on or off). It seems that as soon as I coast for any period, when returning fuel ever so gently, it kicks out of OD and in a few seconds, back into OD.
Is this a potential problem or a just some type of adjustment? I'm on the road Monday for a short trip (actually, my maiden voyage with my trailer), but would be able to get it to the dealer Tuesday.
Happy Holidays!

They will come out of lockup even with tow/haul on. This was a change for me coming from an 02 auto. The 4R would unlock on a downshift but usually not from just from just a momentary coast. The 5R does this as part of it's programing. I'm sure there is someone on this board who could explain why.
Anywho what you are describing sounds like normal tranny operation for the torqueshift. As soon as you release the throttle and reaply it this t/c will unlock. The point I was trying to make about the tac was that unless you were watching at the moment you reaplied throttle you might miss it. I not sure how many highway miles you drive but thats one of those little quirks that takes a few highway miles to notice. The 6.0 is so much smoother and quiter than 7.3 was that some things I used to feel and hear are less detectable now.

Also, if you drive steady with constant throttle input and tap the brake with your left foot, the torque converter will unlock and then lock up again when you take your foot off the brake and that doesn't have anything to do with throttle position or engine load.

My early 03 also unlocks when you let off the throttle even the slightest bit. It works really good for towing. When approaching a hill I let off so it will unlock. The rpm increase helps to keep the engine from lugging. These engines like to rev!
