Do you take the pressure off shifter after shift ? I'm a heel shifter, and if I don't raise heel up after shift it don't work, Not being smart but happens to me sometimes, I have to tell myself to do so. Not so much on the old 11 limited
I switched to Redline syn for the transmission and the primary case at my 1000 mile point. It shifts much better than with the OEM fluids but most of it is the Redline and the rest is break in mileage. I can easily get into neutral now.
I commute twice a day... My office is an hour and fifteen to an hour and a half from home, I do 8 12s, 5am to 5pm, then 4 days off, then 8 12s on nights, 5pm to 5am, then 4 days off then 8 12s back on days... and so on. In the oilfield, we call it an 8 and 4 hitch.
With the drive is basically ends up being 8-15s...
