A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## Other bulletins for the same vehicles and component

- [26\-DS\-001G TSB](/bulletins/11037286.md), 2026-09-11, Service bulletin: POWER TRAIN. Some GV70 \(JK1, JK1A\), GV80 \(JX1\) and G80 \(RG3\) vehicles may have a hum or whine noise condition from the rear differential at certain speeds. This bulletin describes the procedure to inspect the vehicle for the hum or whine noise and, if necessary, to tighten the rear differential lock nut to specification. If the hum or whine noise remains after tightening the lock nut, then this bulletin provides instructions to replace the rear differential or other driveline components as necessary.
- [24\-DS\-001G\-1 TSB](/bulletins/11009768.md), 2024-11-05, Service bulletin: POWER TRAIN. Certain GV70 \(JK1, JK1A\), GV80 \(JX1\) and G80 \(RG3\) vehicles may have a hum or whine noise condition from the rear differential at certain speeds. This bulletin describes the procedure to inspect the vehicle for the hum or whine noise and if necessary to tighten the rear differential lock nut first. If the hum or whine noise remains, then replace the rear differential or other driveline components as necessary.
- [24\-DS\-001G](/bulletins/11000783.md), 2024-06-04, Service bulletin: POWER TRAIN. Certain GV70 \(JK1 and JK1A\), GV80 \(JX1\) and G80 \(RG3\) vehicles may have a hum or whine noise condition from the rear differential at certain speeds. This bulletin describes the procedure to inspect the vehicle for the hum or whine noise and if necessary to tighten the rear differential lock nut first. If the hum or whine noise remains, then replace the rear differential or other driveline components as necessary.
- [24\-DS\-001G](/bulletins/11000781.md), 2024-06-04, Service bulletin: POWER TRAIN. Certain GV70 \(JK1 and JK1A\), GV80 \(JX1\) and G80 \(RG3\) vehicles may have a hum or whine noise condition from the rear differential at certain speeds. This bulletin describes the procedure to inspect the vehicle for the hum or whine noise and if necessary to tighten the rear differential lock nut first. If the hum or whine noise remains, then replace the rear differential or other driveline components as necessary.
- [24\-AT\-003G](/bulletins/11000776.md), 2024-06-04, Service bulletin: POWER TRAIN. When servicing an 8\-speed automatic transmission vehicle with a “Check Engine light” and any of the DTCs listed below, follow the Service Procedure and, if necessary, replace the E\-module.
- [21\-AT\-015G](/bulletins/10253048.md), 2024-04-11, Service bulletin: POWER TRAIN. This TSB provides a procedure to diagnose and repair a transmission for the following Incorrect Ratio DTC \(transmission clutch slipping more than 200 rpm in gear\).
- [19\-AT\-014G](/bulletins/10253043.md), 2024-04-11, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION; POWER TRAIN. This bulletin provides a procedure to diagnose an 8\-speed automatic transaxle with a harsh and/or delayed shift.
- [19\-AT\-007G](/bulletins/10253042.md), 2024-04-11, Service bulletin: POWER TRAIN; POWER TRAIN:AUTOMATIC TRANSMISSION. This bulletin provides a procedure to transfer oil pressure data to the TCU using GDS Mobile. This procedure is necessary to reduce the TCU learning time and improve the shift quality. • Before replacing an automatic transmission: Input the data into the TCU using the GDS. • Before replacing a TCU: Back up the oil pressure data from the old TCU into the GDS and then transfer the data to the new TCM.
- [21\-AT\-012G](/bulletins/10253038.md), 2024-04-11, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION; POWER TRAIN. This bulletin provides a procedure to transfer oil pressure data to the TCU using GDS Mobile. This procedure is necessary to reduce the TCU learning time and improve the shift quality. • Before replacing an automatic transmission \(Pages 2\~3\): Input the data from the new transmission into the TCU using the GDS. • Before replacing a TCU \(Pages 4\~6\): Back up the oil pressure data from the old TCU into the GDS and then transfer the data to the new TCM.
- [19\-AT\-023G](/bulletins/10253026.md), 2024-04-11, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION; POWER TRAIN. If you are servicing a vehicle with a transmission slipping concern, follow the Service Procedure shown below and perform a stall test. This TSB provides a procedure to test each clutch in the transmission. If the vehicle fails the stall test, replace the transmission. PASS: Stall speed is between 1700\~2900 rpm \(See shop manual for stall speed\). FAIL: Engine revs to redline limit \(6,000\~6,500 rpm\). If so, replace the transmission.
