My guess is they eliminated it because of customer complaints. They literally had to release a Service Message to dealers to explain that it’s normal behavior for the 10R to skip gears; people were bringing their vehicles to the dealer complaining that they weren’t shifting properly. Every time the dealer writes an RO and determines it’s normal operation, the manufacturer gets billed for the time as an NPF.
This is the same reason manufacturers went to dummy gauges and “idiot” lights back in the 90’s, the general public are not well informed and think that any variation in a reading means there is a problem.
