Hello everybody,
I have '07 EB V8. Last week I took it to the dealer for the transmission bump feeling when shifting from 2 to 1. I am sure most of you are familiar about this. They did a TSB (re-programmed the TCM and PCM) with latest software.
After the TSB, the transmission issue is gone, its shifting very smooth and no bump feeling at all. However, I noticed engine vibration at idle increased little bit. It idles at 600-650 rpms by the way which I think is little low.
I have a couple questions:
1. did anybody else notice engine vibration after transmission TSB?
2. Is the 600-650 rpm normal at idle? I don't remember what was my idle rpm before the TSB.
I asked the service advisor about this, and he told me that the vibration should go away as the engine is now learning after re-programming but I already drove a couple hundred miles in a week and the vibration is still there.
Its not a big deal, just a slight increase of vibration, but I want to make sure the re-programming was done properly and the current low idle rpms are normal.
Thanks a lot.
