You realize that noise is just the normal sound of the pump at high pressure correct? You simply do not hear it under heavy throttle while driving because its drowned out by engine/road noise. There is no damage occurring, its normal pump operation, and really isn't something that needs "fixing"@jyamona any chance you can port over the tables for ikmos to stop the overdrive pumps from rattling on a cold start under 104f
We are heading into winter and it takes quite a lot longer for our cars to reach 104f so the pump feels like its going to shake it self to bits.
In summer it doesn't last long a mere few seconds but in winter it can last up to a few minutes and sounds horrible.
Don't know if it's causing damage to the hpfp valve operating so hard
