My 2007 LC with 170k miles has shown about 9 on the graduation test once a year for the last 2-3 years. I recently replaced the rear springs with King, and cranked the TB to get the AHC pressures within spec. They are actually right on the low pressure side of spec.
I then did an AHC fluid flush.
My fluid has a tad of froth.
But the crazy thing is that now the graduation test is 14. Is this normal? Possible? I thought 14 was only for brand new globes?
