I rode with two truckers and they showed me how to float the gears but they both were old timers and long ago forgot the mechanics and shifted by sound and feel.

I am an instrument rated pilot so can quickly scan the gauges without getting fixated on the gauges instead of the road. Will install little cheat labels on tach and speedo as markers for shift/gear targets to hit. Will practice on back roads until I get it and I will get it because I have no choice! I have to get it and quick!

Lack of a clutch pedal is kinda hard to learn to back up, but not bad with some practice. I'm glad your moving in a good direction at least.
The problems I had are not that common relative to the many thousands of auto shifts on the road but when they occur, they are extremely difficult to correct because everything is just fine for several hours before all the crap starts again. In my case ~4 hours. I pulled all sorts of codes but one code can trigger several other codes so the codes are pretty much no help at all. The problem was heat related it seems. After the truck was allowed to cool down for an hour or so it was just fine. The autoshift worked just great when working and is light years easier to drive than the manual but my back was against the wall. You probably will never have any problems. Mine started acting up at about 105K miles on the trans and continued to get worse the previous owner told me. He traded the truck for that reason.
Appreciate the feedback from you guys. I hope that my experience might help someone else down the road. My advice would be to not spend much trying to repair the trans. 7K was spent on it by the dealer and I plus the previous owner spent at least that and nothing fixed it.

Those seasoned drivers will make it look deceptively easy. Then again, I guess it is easy to them.

I only drove three months over the road before my hip gave out. Even after three months, I was still double clutching whenever the truck was heavy.

Clean accurate downshifting still seems like a bit of an art form to me. Even my 3 Million mile plus trainer scraped one every now and then. Matching gear, RPM and ground speed has to be done by sound and feel, nobody looks at the gauges.

Save the mountains for last
