Van Flywheel

[dieselson]

My dad's friend has a 2006 duramax work van with a 4L85. The flywheel just broke and he can't find a flywheel at a dealer. My question is, is the the flywheel on a duramax van different than the flywheel on a truck? If so does anyone know where he can get one?

I would think it's the same.

I have not seen one yet but would imagine it will be a two piece unit like our trucks. ( Flywheel and flex plate ) If so, which part is bad, the flex plate or the cast iron flywheel with ring gear?

I have had about twenty van motors roll through the shop and all the flex plates were the same. The local GM dealer bought one from me to put in an ambulance that had the same trans you talk about. Funny thing was it also had a cracked flex plate with that trans.
