Method for Operating an Automatic Transmission

摘要

A method for operating an automatic transmission is provided. The method includes synchronizing a positive shifting element of the automatic transmission, braking the automatic transmission with a first non-positive shifting element of the automatic transmission, establishing a position of the positive shifting element, and increasing a pressure of fluid supplied to a second non-positive shifting element of the automatic transmission if the position of the positive shifting element is an intermediate position.

1. A method for operating an automatic transmission, the automatic transmission having a plurality of non-positive shifting elements and at least one positive shifting element, the method comprising:
synchronizing a first positive shifting element of the at least one positive shifting element; braking the automatic transmission with a first non-positive shifting element of the plurality of non-positive shifting elements; commanding the first positive shifting element of the at least one positive shifting element to actuate from a disengaged configuration to an engaged configuration after said step of synchronizing, a second non-positive shifting element and a third non-positive shifting element of the plurality of non-positive shifting elements being in the engaged configuration at said step of commanding; establishing a position of the first positive shifting element of the at least one positive shifting element after said step of commanding; and increasing a pressure of fluid supplied to the second non-positive shifting element of the plurality of non-positive shifting elements if the position of the first positive shifting element of the at least one positive shifting element is an intermediate position at said step of establishing.
