Sierra 2500 Denali 2WD V8-6.0L (2011)
Note:
*
When the pressure control valve retaining bracket (5) is removed, there are 2 sets of accumulators (3) and springs (6) which may fall from the
bores. Be sure to catch the accumulators and springs so as to prevent damage to these parts.
*
The pressure control valve retaining bracket (5) must not be modified. Note that the angle between the 2 bracket surfaces is less than 90
degrees. Replace the bracket if the angle is 90 degrees or more.
4. To remove the pressure control solenoid 1 (PCS1) or PCS2, remove three bolts (4) and the pressure control valve retaining bracket (5). Remove
accumulators (3) and springs (6) if they do not fall out when the bracket (5) is removed.
5. Note the position of the solenoid connector and pull the solenoid (1) or (8) out of the bore in the control valve assembly. The O-ring on the
solenoid provides the resistance felt during removal.
