Campaign:: 80E006000 on 04/03/1980
Component:: Power train:automatic transmission
Manufactured:: 12/31/1978 - 03/31/1979
Affected:: 364
Defect:: Certain transmissions were assembled with improperly machined forward clutch housings. the resulting incorrect ball check valve seat angles in the pressure exhaust ports may prevent complete oil evacuation from the piston apply area.
Correction:: Vehicles will be inspected and, if necessary, the forward clutch assemblies will be reworked.
Notes:: Vehicle category: trucks and buses with diesel transmissions.system: power train; allison transmissions, model nos. ht-700, clbt-750 andv-730.consequences of defect: trucks and buses with these transmissions may moveforward even when the gear selector is in neutral. this could occur withoutprior warning and could result in an accident.
Campaign:: 81E001000 on 02/11/1981
Component:: Engine and engine cooling:engine:diesel
Manufactured:: 11/30/1979 - 11/30/1980
Affected:: 20,156
Defect:: If excess combustible fluids such as diesel fuel or lubrication oil build up in these engines, the excess fluid can be carried into the intake system through a valve.
Correction:: The crankcase depression regulator valve will be replaced with a road draft tube. this repair is to be done at the same time as the repair for campaign 80c-4.
Notes:: Vehicle category: medium trucks and school buses with 8.2 liter diesel engines.system: engine and engine cooling; crankcase ventilation system.consequences of defect: if this condition occurs, engine speed may increase,independent of throttle control. this could result in loss of vehicle control,without prior warning, and an accident.note: owner is advised not to overfill the crankcase while changing or addinglubrication oil. should loss of throttle control be experienced during vehicleoperation, the transmission should be shifted to neutral, the vehicle braked toa stop, and the ignition key turned off. no attempt should be made to restartthe engine.
Campaign:: 81E002000 on 02/11/1981
Component:: Engine and engine cooling:engine:diesel
Manufactured:: 11/30/1979 - 11/30/1980
Affected:: 20,156
Defect:: These engines have an engine speed governor with a linkage lock that may loosen or completely separate.
Correction:: A new governor linkage lock will be installed. this repair is to be done at the same time as the repair for campaign 80c-3.
Notes:: Vehicle category: medium trucks and school buses equipped with 8.2 liter dieselengines.system: engine and engine cooling; governor linkage regulator.consequences of defect: if the lock loosens, the engine will continue to rundespite attempts to turn it off normally. if the lock breaks, other componentscould be damaged, possibly causing loss of throttle control, without priorwarning, and an accident.note: in the event a loss of throttle control occurs before the vehicle ismodified, shift into neutral and apply brakes until vehicle comes to a completestop.
Campaign:: 84E022000 on 10/10/1984
Component:: Seats:front assembly:seat heater/cooler
Manufactured:: 08/31/1983 - 12/31/1983
Affected:: 3,936
Defect:: Seat warmer may short circuit or overheat due to manufacturing defect.
Correction:: Owners should contact manufacturer for instructions on returning the product for a full refund.
Notes:: Vehicle category: passenger vehicles.system: electric power accessories; seat warmers.consequences of defect: overheating may result in a fire and personal injury.
