Default What year 4l80e do I have?
I picked up a 4l80e. It came out of a 2002 silverado (i saw the truck as they were pulling it out). I keep reading that after 1997, they moved a trans line fitting to the back of the trans? Mine has both holes on the side. What year do I have? Im trying to figure out what fittings I need for my -6an lines since the newer ones require the one with the tube. Thanks.

it says GM-B9 in the casting

That's a 2002, one line on front and one at rear (red caps) the 2BSP signifies it's a 2002.

I think those are for the early year 80E's.

Correct, that Russell part number is not for the newer style. Do not use that.
