Hi BNaylor,
Thanks for the prompt response. I am in the Philippines, GM China released here a re-badged version of the 2004/05 Buick Regal as Chevrolet Lumina. Mine has the LB8 engine 2.5l V6 SFI. I heard it's a derivative of the LG8 with lower displacement. I looked at the parts code in the trunk cover and saw 4T65E MD7 as the transmission code. I usually drive late at night or early in the morning. I don't usually get the symptom unless it's a stop and go traffic for about 40 mins or so. You mentioned it's about the repeated cycles of upshift, will that mean it's ok to drive it to a highway and mostly stay in 4th gear? The city driving is what makes the shift cycles happen so often. Let me know if there's any other info I need to pull-up.
Thanks,
