hi shaun
the cossie 4wd tranny loss can be improved by having all the vc's reset
most of all the cossie vc's are fooked and i bet none of the owners ever had them reset lets be honest here how many cossy people have there diffs service i bet you would just about count them on one hand
all the vc's had 50Nm of torque when they left the factory most of them have got about 20Nm or even less ( lost viscoity)
