Cyclical vibration when sitting at stop lights

Just did a complete trans flush and filter - 5 gallons. Old fluid looked pretty good and not a lot of metal on the pan magnets. Installed Valvoline Dex/Merc - compatible with Mercon III.

Trans has 224,000 miles

New issue:

When sitting at a stoplight in drive, there is a vibration that builds and then stops, builds and then stops, and so on. It takes a couple of seconds to build and then go away. You can set your watch to it - very cyclical.

Shift the trans into PARK and it goes away.

Based on that it is something with trans, when it is "engaged". Seems like a pump is building pressure and then dumping it - but that is just me thinking and not knowing how it really works.

Checked the trans fluid level and it is in the H area - I'll double check in the AM with the engine running, trans in park..

Could an overfill cause this?


Tried searching, but not familiar enough with how the trans works to search for the right key words...
