My regulator was leaking air so back in 2015 I changed it for a new one $450 cdn. I got it from “The Gear Centre” MISSISSAUGA (Toronto Ont) branch 1 (905) 564-8998. They are the Canadian zf freedomline service and parts dealer. They can provide every part needed up to and including a replacement Gear box. Back in 2016 a replacement was $8000cdn which included new clutch, tcu and i think the voltage doubler. They offer phone support.
