Odometer just hit 150,000 miles and have still had ZERO issues with this mod. Just drove from Wisconsin back to FL and averaged 23.1 MPG mostly at 79 MPH. At a steady 60 MPH it'll average 30.3 MPG. Still no issues with the transmission at 150K. I'll do a fluid change with Pentosin again next week since the filter/fluid change was at 100K miles.
