Automatic Transmission "D" RANGE KICK DOWN While operating at speeds below approximately 90 to 100 km/h (56 to 63 MPH), a kick "3rd-2nd" downshift can be accomplished by fully depressing the accelerator. A kick "3rd-lst" or "2nd-lst" downshift can also be accomplished below approximately 40 to 50 km/h (25 to 31 MPH).

Moreover, the line pressure (13) plus the force of the "lst-2nd" shift valve spring oppose the governor pressure (15) at the "lst-2nd" shift valve (D, and thus, perform "3rd-2nd" or "2nd-1st" downshift operation.
