On certain vehicles, the nut that attaches the transmission gear selector shaft to the control valve lever in the transmission may not have been adequately tightened at the transmission plant which had been diverted from the production line for repair. This may result in the transmission not actually being in the gear indicated by the gear selector lever and lead to unexpected vehicle movement.
Certain vehicles fail to conform to CMVSS 114 - Theft Protection. These vehicles are equipped with a mechanical override that could allow the ignition key to be removed with the shift lever in a position other than park. In addition, these vehicles have an override that can allow the transmission to be shifted out of park with the ignition in the off position. These overrides are not permitted unless the vehicle has a locking steering column and the overrides have covers that can only be removed with a screwdriver or other tool.
Safety Risk
No risk description available.
Remedy
Dealers are to eliminate these conditions by disabling the overrides.
On certain vehicles equipped with a Tiptronic transmission. The automatic transmission lever cable may be incorrectly adjusted. It may be possible to shift the transmission out of park after the ignition key has been removed from the ignition.
On certain vehicles, water could become trapped in the throttle cable housing and freeze during extended cold temperatures, potentially resulting in a loss of throttle control.
On certain motorcycles, the 3rd and 4th gear (shift) wheels may not be securely seated on the intermediate shaft. Consequently, when attempting to shift from 5th to 6th gear, engagement of two (5th and 6th) gears may occur simultaneously. If this happens, the gear wheel may crack resulting in a loss of transmission capability, or, a lock of the transmission may occur. If the latter occurs, the rear wheel may lock which, depending upon traffic and road conditions, and the rider's reaction, could affect the stability of the motorcycle.
On certain vehicles, the transmission shifter cable may become dislodged from the shifter cable bracket resulting in incorrect gear indication, which can include the park position.
Safety Risk
No risk description available.
Remedy
Dealers will install a strap to the shifter cable adjuster to prevent the cable from dislodging from the bracket.
On certain vehicles equipped with automatic transmissions, the parking pawl actuating rod ("parking rod") spring retainer may be defective. The parking pawl may not engage the parking gear fully and could cause the vehicle to move if the parking brake is not applied.
Safety Risk
No risk description available.
Remedy
Dealers will replace the automatic transmission parking rod assembly. Replacement parts will not be available until January 2003.
On certain motorcycles, a flange on the transmission output shaft can fracture resulting in engine damage with the possibility of engine lock-up, which poses the risk of an accident resulting in injury or death.
Safety Risk
No risk description available.
Remedy
Dealer will replace the transmission output shaft.
On certain motorcycles, the hex nut that secures the front drive belt wheel to the gearbox output shaft was torqued to a value less than specification during the vehicle assembly process. As a consequence, the nut could loosen during vehicle operation. If this happens, the belt wheel would itself loosen on the output shaft, resulting in damage to the internal splines of the wheel and to the external splines of the output shafts as the vehicle is operated. Over time, the splines could be damaged to the extent that the output shaft would no longer operate the drive belt, resulting in a loss of drive capability at the rear wheel.
Safety Risk
No risk description available.
Remedy
Dealers will check the torque of the hex nut and adjust is necessary.
On certain vehicles, the rear drive belt wheel could crack and eventually fail causing the drive belt to derail. This would result in a loss of drive to the rear wheel.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the rear drive belt wheels for certain production numbers. Only wheels with those specific production numbers will be replaced.
On certain vehicles equipped with manual transmissions, the shift cable could detach from the transmission shift linkage while the driver is attempting to change gears. If the transmission moves into neutral and remains there, the ability to accelerate or maintain speed will be lost, increasing the risk of a crash.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the shift cable and, if necessary, install a retaining clip over the end of the shift cable to prevent it from detaching from the transmission.
Certain passenger vehicles built by Mitsubishi Motor Corporation. A condition exists that allows oil to leak from the all-wheel drive transfer case. Low oil levels in the transfer case could cause bearing damage and result in drive train lockup, increasing the risk of a crash.
Safety Risk
No risk description available.
Remedy
Dealer will inspect the transfer case and affect repairs as needed.
On certain motorcycles, it is possible that the clutch slave cylinder may leak internally causing the clutch control to jam. This could affect the control of the motorcycle and cause a crash.
Certain medium duty tilt cab trucks equipped with manual transmissions. Some of these vehicles have a condition in which the clutch master-cylinder pushrod end that attaches to the clutch pedal pin can wear prematurely. The first noticeable effect of this wear could be the clutch pedal not returning completely to the full-up position. If this occurs, the fast-idle engine speed control may not function. If the clutch master-cylinder pushrod end wears sufficiently to allow the attaching end to bend open or break off, the pedal pin would detach from the clutch rod link and the clutch would engage. If clutch engagement occurred while the vehicle was stopped, with the engine running and the transmission in gear, and if the brakes were not applied, the vehicle could move forward if the transmission were in a forward gear, or rearward if the transmission were in a reverse gear.
Safety Risk
No risk description available.
Remedy
Dealers will install a new clutch master-cylinder assembly and clutch pedal assembly.
Certain manual transmission trucks equipped with the FX4 package. The rear axle differential case could fracture under a high torque event such as when customers accelerate rapidly from a stop or when a spinning tire suddenly gains traction. Differential fractures could potentially result in wheel lock-up.
Safety Risk
No risk description available.
Remedy
Dealer will replace the rear differential assembly.
Certain (4 wheel-drive) Trailblazer and GMC Envoy vehicle. The calibration of the active transfer case control module may cause insufficient high speed gear engagement. If the gear is not engaged, the vehicle can roll when the transmission is in "park" and a crash could result without warning.
Safety Risk
No risk description available.
Remedy
dealers are to reprogram the active transfer case control module (ATCM) calibration to increase gear engagement.
Certain sport utility vehicles Trailblazer and GMC Envoy (4 wheel-drive). The calibration of the automatic transfer case control module or a range shift collar that was not machined properly may cause insufficient high speed gear engagement. If the gear is not engaged, the vehicle can roll when the transmission is in "Park" and a crash could result without warning .
Safety Risk
No risk description available.
Remedy
Dealers are to perform a "clean neutral" test, as described in the bulletin and if the ratcheting noise is detected during the test, the dealers are to replace the transfer case.
Certain 4WD vehicles were built with a range shift collar in the transmission transfer case that contains cracks. This condition could result in a complete fracture of the range shift collar and subsequent loss of vehicle forward and reverse gears, and the inability to maintain "park" position. This increases the risk of a vehicle crash resulting from unintended movement of a parked vehicle.
Safety Risk
No risk description available.
Remedy
Dealers will replace the transfer cases and update the control module calibration.
Certain passenger vehicles. The rough surface of the heater blower resistor's stainless steel blades can damage the copper surface of the wiring harness connector. The damage could, over time, cause increased resistance in the connector and, due to subsequent terminal relaxation, result in an open circuit condition. The heater blower resistor may overheat causing the attached electrical connector to melt, creating the potential for a fire.
Safety Risk
No risk description available.
Remedy
Dealers will install a new heater blower resistor and a new wire jumper harness.
