Also, it likely unlocks the convertor often, and I'm not sure that should be read as lack of power as much as it's geared such that it's simply rev'ing too low (so as to reap mpg's).
I wonder if the cable is opening the throttle body / plate / butterfly / whatever fully.
I haven't checked if it's opening all the way, I believe it is but I'll see. At 60 mph in the hills it'll drop into 2nd gear and scream at 5,000 rpms and continue to slow down.
Something is wrong then, seems odd that it runs well the rest of the time, cars get a bit tired with miles but not that much.
Fuel or air restrictions, or maybe the timing is off somehow?
