Tonight was a beautiful night here in NW Ohio, so some country road cruising was in order. Unfortunately, I barely got the Galaxie home. I slowed for somone making a turn, downshifting into 2nd and then got into the throttle once I was able. It accelerated as usual and I upshifted into drive--it free revved a bit and then was fine. it did it again but then stayed in drive. I went straight home. It felt like there was some mild vibration, but I chalked it up to the road. I turned down my road and it didn't want to go into drive, but manual shifting got it there. Went to put in garage but had to back it up to line up, but it was done. Checked fluid, looks good but may have been a bit low, added some fluid, started engine and tried getting into gear--nothing. No forward or reverse, thought I may have heard a little "sheet metal" like sound, very little. Now, with car in park if I start engine there is a vibration.
Any thoughts would be greatly appreciated.
