No worries SteveR. Mine stopped the hunting as soon as the Life Guard was put back in. If you want to go to the real stuff Precise or Precision Automatics in Osborne Park are the best for price and service, no new sump included as it was already steel. $530 for full flush and filter usuing Life Guard and fit new heat exchanger (I supplied the heat exchanger) others wanted as much as $850 to just do a dump and half fill.
