There is a sticker under my hood, and another sticker on my ECU.

Both of them have the same number.

56044562CE and the date: 4-12-06.

What was this update? What did it do? My tranny locks up at 58 MPH in overdrive so I assume this is not the F37. Ideas?

There were lots of updates early in the life of the US CRD's trying to fix "THE SHUDDER" and other items.

If you go here you'll find the numeric numbers are for the TCM and ECM part numbers the Alpha charectors are the flash revision.
