Service Magazine, SEPD0679, 14 April 2003, "Correction to Testing and Adjusting, "Transmission Testing and Location of The Pressure Taps"". The existing article is incorrect. Refer to the information that follows.Testing and Adjusting, SENR4770, "966F Wheel Loader Power Shift Transmission", "Transmission Testing And Location Of The Pressure Taps". This module is part of Service Manual, SENR4765.

A portion of the existing information is incorrect. Replace the chart for the transmission pressures with the following information.
