the 230 lbs is for ZF S6-650 model.

So Pete you are right about the weight is about same as 4l80.

I believe the 4L80E weights 230lbs including torque converter dry......the ZF s6-650 you posted up is a truck trans, but the ZF s6-40 that comes in at 170 pounds dry is lighter. I think the monster flywheel used for the 4l80e coversion is about the same as a fidenza aluminum piece......should of weighed it when it was out...oh well.
