PIP5213D2017-08-15. Service bulletin. POWER TRAIN. This Preliminary Information communication advises the technician that the part restriction on the 8L45/8L90 8 speed and the LCT1000 6 Speed Allison automatic transmission has ended.
PIP53372017-08-15. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; POWER TRAIN:AUTOMATIC TRANSMISSION. This Preliminary Information communication provides information to the technician on the step to diagnose and repair the vehicles that may have a shake or shudder during light throttle acceleration, between 30 and 65 mph steady state driving. Also shudder feeling that may be described as driving over rumble strips or rough pavement. Technician will drive the vehicle and monitor the torque converter clutch slip. The torque converter clutch slip speed should be 10 rpm or less also note if the shudder takes place during torque converter clutch apply. If the torque converter clutch slip speed is in the range of 10 RPM or less the condition is possibly related to engine performance. If the shudder is only present in 4 cylinder mode and torque converter clutch slip is 10 rpm or less deem the shudder concern normal characteristic of Active Fuel Management. If the slip speed is beyond 10 rpm or there is shudder during torque converter clutch apply the torque converter will need to be replaced with a updated part number.

PIP5337G2017-08-15. Service bulletin. POWER TRAIN; VEHICLE SPEED CONTROL:LINKAGES; SERVICE BRAKES. This Preliminary Information communication provides information to the technician on the step to diagnose and repair the vehicles that may have a shake or shudder during light throttle acceleration, between 30 and 65 miles per hour steady state driving. Also shudder feeling that may be described as driving over rumble strips or rough pavement. Technician will need to run the vehicle in three different operational modes. The three modes are Normal, torque converter clutch open, and torque converter clutch closed. Technician will need to press and hold the tow-haul mode button for five seconds to disable grade braking to prevent downshifts during test. Technician will need to duplicate the concern in Normal mode. If the concern is gone in torque converter clutch open and closed then the torque converter should be replaced. If the concern is not present in normal mode, torque converter clutch open, and torque converter clutch closed the concern is not with the shudder. Technician should use of the PICO scope and Noise, Vibration and Harshness software can be used to confirm torque converter clutch shudder, Engine, Tire or Driveline component related conditions. Flush the cooler lines and cooler using DT-45096 transmission oil cooling system flush and flow test tool when the torque converter is replace.

PIP52502017-08-15. Service bulletin. POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE); ELECTRICAL SYSTEM. This Preliminary Information communication provides information to the technician about vehicles that may have a Service 4WD message on the Driver Information Center. Technician may find C0398 or C0326 stored in the Transfer Case Control Module. Technician should reprogram the Transfer Case Control Module using Service Programming System for the updated calibrations to resolve this concern.
PIP5211B2017-08-15. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN; EQUIPMENT ADAPTIVE/MOBILITY; ENGINE. This Preliminary Information communication provides information to the technician the steps needed to diagnose and repair vehicles with a rough idle and/or vibration at idle in Drive. This condition will not be present in Park, or Neutral. This concern may be caused by ground out within the one or both engine mounts. Technician will use CH-51450-A (Pico Oscilloscope) to measure the vibration disturbance. If the vibration concern is E1.5 in the horizontal / lateral direction with Pico sensor mounted in seat track as indicated ? continue with steps to reduce the amplitude of the vibration by adding spacers in key locations to reduce ground out within the engine mounts. The 6.2L engine has a characteristic E1 which can be felt, and may be described as a lopey idle. Do not confuse 6.2L E1 characteristic (not caused by mount ground-out), with E1.5 normal idle characteristics being transmitted into the truck via ground-out thru the engine mounts. If measuring high at the seat track 12 mg or greater; replacement of the engine mounts should help reduce the amplitude of the vibration. If the disturbance measures at the seat track as E 1.5 lateral in the range of approximately 2.5 - 8 mg using a tri-axis sensor. Then place tri-axis Pico sensor on the inboard seat track forward-most location to record measurement of the rough idle vibration concern. With the Heater-Vent-Air Conditioning on perform several short heavy launch events from stop to stop to bring the temperatures back up while attempting to re-create the rough idle vibration in Drive with Pico sensor placed on inboard seat track; while the vibration is active ? Record Pico reading. This method seems to provide better results than extended test drives. If the Pico reading for E1.5, with vibration active, at specified seat track location measures close to 2mg or less use Service Information to diagnose rough idle / vibration. If the Pico reading for E1.5, with vibration active, at the inboard forward seat track
