Donnie,
The reason I said the code is BJ, is that is what is listed on this build sheet for a 69 Chevelle L78 with auto trans. See below:
This is a known low mile original survivor car. I deleted the VIN intentionally. The car is real with less than 5K on the odometer.
This is the second L78 auto 69 Chevelle with the BJ rad code that I know of. I can't guarantee the radiator tank codes at this point. What I mentioned earlier was based on the ebay auction for that tag. I know the IA tank code is good, not 100% on the trans cooler side of the rad. Jim, do you have a 3 core 69 BB auto trans rad to shed some light on the tank codes?
