Hi guys. I have a 57 bird with a Fordomatic Tranny. The tranny works great with nice smooth shifting. I had something strange happen and was curious if anyone has experienced this. I put the shifter into Park and left the car in a lot. Apparently the shifter had not locked into Park to keep the car from rolling. When I jumped into the car, the car started rolling back immediately. It almost felt as if the locking mechanism was in between teeth. As the car rolled back I could hear the locking mechanism riding over the teeth that lock the tranny. It is the first time it has happened since I have owned the car and has happened one more time since. I now let the car roll a bit if it doesn’t lock the first time. As a note on very rare occasion (1 out of 30 times) I can tell you that sometimes when I shifted the car into Park I would hear a short almost grinding noise that would last a split second. I now turn off the car before I put it into Park as a precaution. I would think it is probably related.



Thanks
