ATTESA AWD system service,dont ignore the transfer case

the attesa ets system in the gtr uses an electronically controlled multi-plate clutch in the transfer case to distribute torque. the fluid needs changing every 20,000km with genuine nissan transfer case fluid. if it overheats from old fluid the clutch packs burn out and you lose AWD. replacement is $3000+. the service is $120 in fluid. theres also a filter inside the pump that nobody checks. pull the pump and clean the filter screen at every second fluid change.
