What is your question?
I drive a 2007 Pontiac G5 with an automatic transmitions. It does, however, have a tachometer also and I have noticed that the engine seems to prefer to shift at somewhere 3500 RPMs and 4000 RPM. There have been times, however, where I have had to hit the accleerator petal quickly like when I have had to pull into traffic on an Interstate Highway and the RPMs have dramaticly jumped to 5000 to 6000 RPM. While the tachometer gauge "red-lines" at 7000 to 8000 RPMs, I just want to make sure that I have not done any damage to my engine when I have been forced to make it jump to 5000 to 6000 RPMs. Please let me know. Thanks.
