Noob question 727 really low shift points

TrailBeast said

Makes sense to me, but I can't help thinking most of the problem right now is that it's too tight on the TP adjustment.
That will make it delay the shifts and rev higher before it does shift.
In fact you can adjust it so high that it pretty much won't shift at all until it gets way up there in RPM's.
I'll tell you a clue about it being adjusted to tight, and that is if you put it in D and go but it doesn't upshift AND also does not have engine braking when you let off the throttle.
Meaning you let off and it feels like it's coasting in neutral.

That's exactly why I put that spring in the front of the throttle connection to the carb, holy **** you're good. It felt like the throttle wasn't coming down at all, I thought that was from the cable so I put a spring in front to pull back on the assembly in case it was getting stuck because of the alignment of the throttle cable.

So, the problem has to be somewhere in the run between the transmission and where it comes up the firewall (Lokar said I should have to cut some off because it should be too long and I thought it was too short). Putting the adjustment there was the only way it would fit onto the throttle linkage when the linkage was wide open which is I thought the way it was supposed to be adjusted. With the adjustment right in the middle on the TV linkage and I was shy of the throttle connector by about an inch or so.
