Shhot, I was hoping it somehow monitered the TC slip/rpm diff. between the motor and trans. Thanks for clearing that up.
I couldn't think of what DP would be, even checked "the list", makes sense.

Okay... Here's one that will make you scratch your head (or point to a solution instead). I realized that the slippage only occurs when I put on my left turn signal, and only if I'm in the top two gears. Without fail. Any ideas?
Otherwise, it's just noisy, may shudder in the beginning of any gear, shifts late when cold, and when under WOT, the engine revs great, but the truck stays behind. I'm beginning to think that my rough idle is related to the transmission in some way, also. When i'm under the truck (idling in park), the engine seems to be purring away while the chugging sound seems to come from the transmission area. Of course I could be mistaken, but this is my observation. Hope this info lines up with someone's theory...

My '97 Power Stroke needs a new bed. In fact it's white and if I knew where you lived I come and steal yours. LOL
Did you have any problems mounting yours?
What year is the white bed you put on your truck?
I've heard there are some wierd size '97 beds/trucks.

Both my center and passenger brake lights are out. I'll be replacing those tomorrow, and I'll post my results...

It does do that but not a gear change. The PCM won't allow the TC to lock until a certain temp on most PCM calibrations.

I totally belive you about the RPM/shifting thing but it sure SEEMS like it runs to a higher rpm when cold.
I'm assuming the TC only locks in OD?

I'm going to look at a white bed about 80-100 miles away hopefully this weekend and I don't want to come home with a "yard ornament".
Now I'll quit

Sounds like a lockup issue to me too, what does the trans have to see to stay in lock-up?
As for the vibration, I think driveline vibration usually gets progressively worse with speed. You could check for TC shudder by stepping on the brake and giving it a little fuel while in gear, but be careful, this will heat up the tranny fast!
