Hi Will,
I think I understand now, the lack of hunting in your fully automatic mode, when the pedal is firmly held to the firewall. That must be due to the payload or steeper Smokies. The easier hills I recall only required part throttle yet we'd be losing ground running in 4th.
But, I failed to include my experience of one of those trips across the hills and into the Midwest. The one in our '79 with AW55 three speed auto. Hundreds of miles would be cruised at 4000+ rpm. Aside from the noise and not-so-great fuel efficiency, we could not detect any ill effect on the motor or its cooling. But, the noise is unnerving and a frequent reminder of the luxury of overdrive ratios.
Regarding your looking forward to rebuilding an automatic, I think we differ there, though I'd be prepared to if there were not so many good ones in the yards. There's this vague memory I have as a kid, Torqueflite in the bathtub. Then back in there again. Then conversion to manual.
But you do mention a 760. ZahnradFabrik? I have it in my mind to stay clear thereof.
I like your thoughts about customizing improvements, something I've not done much of in the Volvos. When I did, I used to worry when I left town.
Thanks for the offer!
