Quick 2020 question for y'all...
After waiting out the break-in period, I finally did a dry run with my 16', 2700' dry trailer up an extremely tough grade, the first hill on I-70 in Colorado from Morrison to Evergreen, at 60-62mph.
The 4R did... pretty well, considering I was cut off and had to slow to 20MPH at the bottom of the hill. Standing on the accelerator, I got to 60 MPH decently quickly but the engine was SCREAMING in 2nd gear @~5,500 RPM. The timbre of the engine started to sound slightly more... how to say it, high pitched or metallic-y? And right before it shifted from 2nd to 3rd, there was a sort of high pitch hum that dissipated after the gearshift. Engine temp remained normal, no warning lights.
Two big questions:
Is it OK to absolutely flog this thing like I did, when necessary? I plan on a severe service maintenance interval, with 5k synthetic oil changes and likely transmission drain/fills every ~2 years. Is that enough, or will my 4R eventually get mad at me and blow up?
Are those engine sounds normal? I know engines can sound funky near their redlines, but I want to make sure I didn't mess anything up (or come close to it).
Thank you from the hills!
