I removed the motor, trans and transfer case from the vehicle. I unhooked the transfer case at the line that connects under the vehicle. Do I need to have the system bleed or can I hook it back up and put fluid in and it will bleed its self.

If I need to bleed it I need to get some software or take it to the dealership?

 

I thought trans, transfer case, and rear diff are drain and fill. Not pressurized or software needed like the ACD

 

No the acy pump has to be activated to bleed the system
