INTRODUCTION

This Service Information bulletin announces availability of a new control valve assembly (valve body) designed to prevent false detection of DTC P0841 and/or illumination of the AT Temp light. Testing has revealed in some limited cases, air bubbles (aerated fluid) may enter certain pressure circuits within the control valve assembly causing fluid pressure control and adjustment to be calculated incorrectly resulting in DTC P0841. The shape of these circuits has been changed to prevent this occurrence.
