The Transmission Control Unit (TCU) is adaptive. If you drive gently it holds gears longer. If you drive sporty, it shifts sooner.

That said, the shift between 3/locked and OD/unlocked is barely noticeable. What you 'feel' is actually OD to OD/locked.

Towing, or going uphill, steep incline will change them too. And a bad TPS will screw with points too.
Here is an old thread that had a long discussion about the shift points.

Mine are all Renix rigs, 87-89, so they may be different.

The only really well known shiftpoint is first to second in the 1-2 gear position, it's approximately 4500rpm or near redline. I'm reasonably certain that throttle position doesn't make much difference but honestly if you hit 4500rpm with the shifter in 1-2 you are probably giving it the stick :firedevil
The rest are, as everyone else already said, adaptive.
