Ok well I have an 01 DTS with 28k on it so I guess the 5 yrs is up and I should do the coolant?

Does anyone know anything about the lower valve body issue these cars had? What are the symptoms of a valve body being bad?

I have an strangeness that I feel but I think it's more like TCC solenoid. Sometimes when driving slow like after just pulling out of a parking space when you go to stop the car will buck like a manual shift while not pushing in the clutch. It won't stall but it acts like that? I think this only occurs within a minute or two after starting the car.

What you are discribing is a stuck TCC solenoid (not disengaging). There should be a DTC set.

thats pretty disheartning to hear of tranny probs at 28K
Maybe a fluid change will help it

I don't see any code regarding this. I'm going to take the car in to have this looked at while I'm still in warranty. Does everyone agree with this diagnosis?

I had also mentioned that there was talk about the lower valve body being a problem on these. Does anyone know what the symptoms of that would be?

Thanks

By lower valve body, I assume your are talking about the shift solenoids. The symptoms are failure to shift.

Well I read on either the Parts America site or Autozone they have a Consumer reports style reliability chart and for 2000 and 2001 they claimed those 2 items were problematic.

I don't really know what the lower valve body does or is. I'm very mechanically inclined but I honestly have never been inside a trans none the less an electronic one.

But we do all agree that my issue sounds like the stuck TCC correct?

Sounds like it to me. Check the disengage switch on the brake pedal.

No I hadn't. I didn't realize that existed. I have about 1000 miles left of warranty so as soon as I return from Bermuda I'll get it to the dealer.

Thanks for all of your help
