Very true, though I think it's about where you put your foot for the autos.
When I originally moved my kick-down cable, I wanted the car to shift sooner..........ONLY for where I usually keep my foot........(approx 1/3 of the way throttle open).
In this case, I was oroginally shifting at like 15mph & 30mph. FELT LIKE A DOOOOOG!!
Once I adjust the cable a couple turns, it went to shifting at about 22mph & 40mph.
I adjust it one more time & got it to shift at 25mph & 45mph regularly.
Now..........since then, I've learned where to have my foot if I want it to shift later. Only problem is that it's different in both shift points.
1st to 2nd...........it'll shift at 25mph anywhere from 1/3throttle up to 2/3throttle. You have to reeeeally open to 3/4 or full throttle to get it to hold 'til 30 or 35mph.
2nd to 3rd..........it'll shift anywhere between 40mph & 60mph depending on where I have my foot. This one is much more progressive so I have much more predictable control over the shift point.
What's funny is that after I get out of the '95 Prizm & drive my '98 Camry........I'm freakin' amazed at how intelligently the Camry shifts. Nothing short of the word "intelligent" describes how the Camry shifts. (like butta'!!!) But I still like my Prizm 'cuz it only cost $1,800!!!!!!!!! LOL!!!!!
