Hi Christopher,
Thank you for the donation.
It is difficult to say if it is grade logic or the trans shifted slightly harsher than normal.
A longer period of monitoring would be required to understand the situation. As you already knows, grade logic works according to the condition and data available to the PCM.
Some transmission don't fail even after a long period of harsh shfting and the only problem you would encounter is the harsh jerks occasionally when throttle pressure is applied to accelerate.
Forget about worrying when the transmission is going to fail. If it is going to fail, there is nothing that you can do to stop it. Whatever maintenance and fluid change should be done accordingly and the rest is beyond our control.
