I have a different question. I have seen in several posts on this forum that says the transmission "learns" over time. I have not seen this information in any official Toyota document. Can you point me to some documentation regarding this function.
If you Google "toyota transmission artificial intelligence" you will probably find at least a dozen of references to the AI capabilities of Toyota automatic transmission ECU.
Here is just one example from an Australian Toyota dealer
New Toyota Rav4 for sale in North Brisbane - Torque Toyota
About half-way down the page you will find references to AI shift control.
Artificial Intelligence (AI) shift control
RAV4's 6-Speed automatic transmission incorporates Artificial Intelligence (AI) Shift Control, which senses road conditions and driver intentions and optimises shift patterns accordingly. This helps to make RAV4 more responsive and smoother to drive on changeable terrain.
The AI program of the ECU actually "remembers" the conditions from several past driving cycles (road conditions and drivers behavior) and uses this information to anticipate shift points. It basically assumes that the current road conditions (flat vs. inclines, slow-speed city driving vs. high-speed highway) and that the driver's behavior such as rate of acceleration ("leadfoot" vs. "old granny") will be the same as in the past few cycles. If the road conditions and driver's behavior are significantly different, the ECU will re-learn the new parameters after a few driving cycles.
If I have time later today I will try to find more technical description in the Toyota documents I have.
