Gini, A couple of things come to mind, but first, the trans fluid has to be checked with the vehicle on flat ground. Checking it on an incline will affect your reading. Some things that come to mind are: 1) Fluid level is wrong, when tested on flat ground (normal engine idle) 2) Engine idle too high 3) Hydraulic (transmission) pressure too high (can be caused by misadjusted TV cable) 4) Bad engine mounts ==== |

I had some temporary transmission glitches in my old Audi when I parked it front up on my driveway and had to begin parking front down. All was fine after that. With my Silhouette, I learned to back up my driveway. Now, I put the van in neutral to descend the driveway instead of 'Drive.' If I shift from Park directly to Drive on the hill, it does clunk. Now, I don't shift into Drive until I am on the level. Hope this helps. ==== ==== |

Bad motor mount can cause rattling, but so can may other things. I'd have to be there to see where the rattle are coming from.

check the vibration/rattle last oil change (before warranty expiration) but he
said he couldn't hear it. I should have insisted on taking him for a ride to
point it out. Maybe he'll hear it at next oil change (outside warranty). It has
gotten slightly worse. Thanks for your input.
