Also chances are if it came with a 4l80 attached then its more than likely an LQ4 and in that case you the th400 will bolt right up

I will have to check on the flex plate. It is wrapped up at my dads shop right now. It did come out of an Escalade and I assumed that it was a 4l80, it was sold to me as one and I resold it as one. I ran the numbers from the motor and it is definitely a LQ9.
