wagonman,
What is the date code of the transmission in question? Date code should be on the passenger side, near where the main case and tailhousing bolt together. VIN will most likely be on the top of the transmission, near where the main case and tailhousing bolt together.
While it is in the car, it will be difficult to read the VIN on the transmission. You can try a small inspection mirror with an extendable handle but even that doesn't work sometimes.
