STARTER, Engine Prior to starter removal: 1. Inspect and check all connections to the starter motor solenoid a. Unplug and plug-in the T50 1-way connector as needed to verify the connection is good & tight and check for any bent pin in the connection. b. Inspect the T30 connection (i.e. B+ M8 threaded stud & nut) for tightness to assure cable ring terminal connection is secured and tight (use torque spec per service manual). 2. Check/verify all grounds in the cranking circuit a. Check tightness of mounting bolts that secure starter to the engine block b. Check main ground from engine to chassis c. Check battery ground cable connections are clean and tight d.Potentially, loosen both starter motor bolts, without removing, and re-tighten to torque specifications in the service manual e. After all steps above are complete, attempt to crank the engine to verify if improvement has been made (i.e. the steps fixed the customer complaint) 3. Conduct the voltage drop test (starter feed circuit) per the service manual before removing the starter motor 4. Starter Removal: conduct the removal if above steps do not fix the complaint a. Conduct bench test by applying 12 volts to motor T30 and T50 connections (i.e. conduct simple free speed test) b. Free speed test should result in starter motor pinion travel to pinion stop and rotation with normal rotational noise (i.e. no grinding, scrapping, etc.) c. If any abnormal noise is present, replace the starter motor 5. During starter removal, also remove and replace the two starter mounting bolts. Return the bolts with starter motor for analysis at QEC and the supplier warranty analysis lab.

90040092022-09-26. Service bulletin. POWER TRAIN. Transmission Kit with Torque Converter 1. All Promaster (VF) 3.6L/62TE equipped vehicles. If the transmission bracket to the transmission case fasteners are removed during servicing, the fasteners (Part Number 06511385A$) are one-time usage. Vehicles built prior to 10/23/2015 requires Service Kit PN 68461214AA; includes Transmission Isolator PN 68264483AA, and Adaptation Bracket 68264479AA and Fastener Service Kit PN 68329056AA Vehicles built after on or after 10/23/2015 will require only the Fastener Service Kit PN 68329056AA. 2. All 3.6L/62TE equipped vehicles. If the vehicle you are repairing has a crack in the flex plate or failed pump bushing inspect and confirm that both (2) dowel pins are present in the engine block, which align the transmission center line to the crank shaft centerline and visually inspect the dowel alignment holes in the transmission case. If the holes are damaged or elongated the transmission should be replaced to prevent further damage to the transmission/flexplate or pump bushing due to the inability to properly align the engine to the transmission during the repair. 3. All 62TE equipped vehicles. If pump bushing is scored or damaged and the dowel pin alignment holes are ok, replace the pump assembly as opposed to complete transmission. 4. All 62TE equipped vehicles. If vehicle is jerking/slipping with MIL code(s) P0740 or P2764, check TCC Solenoid operation. If TCC Solenoid is ok, the codes are indicative of a torque converter failure. Replace the torque converter.
