WARNING: This page is about a different car, the 2004 Dodge Pickup. However, it is still accessible from the selected car via links, so may be relevant.
Transmission identification numbers are stamped on left side of transmission case, just above the oil pan gasket surface. See Fig 1 or Fig 2 . Identification numbers may be required when ordering replacement components.
