How to identify my auto trans??

[PeteBratt]

Want to check if my auto trans is the original.  I have looked quite a bit but cant find any palce to identify the casting numbers.  Can anyone send me a link?

By the oil pan rail there is # should be the VIN and it should match. Maybe not all the letters but most of them. If the trans is dirty you won't see them without using some brake cleaner or something to clean it up. Think its the drivers side but not positive.

the last eight numbers on your trans. are the same as your sequence number on your VIN.

The original post doesn't mention a year, some '68 and all '69 and later will have a partial VIN stamped on a raised pad on the passenger side bellhousing; '67 and earlier can't be verified as being original to any car.

The number stamped on the drivers side pan rail is the part number and build date, this can be used to verify that the part number is correct for the engine and the date coincides with the car build date.
