I am getting a whining under load in 4th and 5th on my '02 sedan with ~20k. I drained the stock oil about a year ago and put in Mobil1. I posted then due to the "extra" bolt I found on the drain plug. Did I mention Mobil1 sucks? I live in podunkville, so I had to get RedLine delivered. Great stuff!! Most of the grinding getting into 1st and reverse immediately went away. The whining started about a month ago...any ideas?
