    Do the rpms constantly oscillate up and down a few hundred rpms? If so then click on the info link in my sig and it will describe what is going on and is a fairly common problem. It is a trans issue but tuning can bandaid it sometimes if you have a tuner.

    Yeah, sounds like what you have on your site. How bad is it to drive it like this? I can get a hold of a scan tool thursday at school and check the stuff you have listed.

    You can drive a long time with that problem, it is more of an annoyance than actually causing any harm.

    Trannyman, Dude, 2006_GP_3.8_4T65E_96,000mi

    Exactly what you describe on your page : RPM bounce, Started about 1000 mi after the fluid flush / exchange, never happened before, very slight, hardly noticeable, very annoying.

    Lubegard Platinum ??? Any Opinion ???

    Just started getting the same issue with my car a few weeks ago, after it sat for about 2 weeks. Anyway, I put one bottle of lubegard red in, and started driving the car regularly again. Just brought it on a 2400 mile trip (NJ to FL and back) and about 6-7 hours into the drive down to FL, I noticed the rpm jumping completely stopped, now the car drives perfect again. It has been perfect since. Maybe it was just a sticky valve after sitting so long, but regardless its better now.
