VALVE BODY MODIFICATION
To eliminate transmission shudder during the 1-2 shift under acceleration, a revised transmission valve body has been incorporated.
Transmission Part Number EBC 2164 replaces EBC 1171, from engine No. 9DP 126748, VIN 526305.
A quantity of the existing transmissions, EBC 1171, had the revised valve block incorporated before this change and are identified from transmissions
serial number 391-676802, which were introduced at engine number 9DP 108835, and VIN 522801.
Where instances of this complaint are reported on XJ6 3.6 models, the valve block assembly can be replaced by a revised valve block, which is available
as a separate item.
Installation Procedure:
CAUTION: Keep dirt from entering the transmission during this procedure.
