Automatic shiftlock, checking function (automatic transmission) 
The automatic shiftlock  uses an electric solenoid to  lock the 
selector  lever in Park or Neutral.  Depressing the foot bralte 
with  the ignition on energizes the  solenoid, allowing the lever 
to  be  moved into a drive gear. The solenoid is  energized only 
when  the engine  speed is  below 2,500 rpm and the vehicle 
speed is below 
3 mph (5 kph). The solenoid is  mounted in the 
right side  of the selector  lever housing.

Shift interlock, checking function 
(automatic  transmission) 
4 The shift interlock uses a cable between  the ignition switch 
and  the shift  lever  to lock  the shift lever  in the park position 
when  the key is  in the off  position  or removed.  This feature 
also  prevents  the key 
from being  removed from  the ignition 
lock  until the  selector  lever is  in Park. 
Shift selector lever  to Park  position and  turn ignition key to 
the  off position. 
Remove ignition  key.  Checlc that selector lever cannot  be 
shifted out  of Park  position. 
Turn  ignition  lkey on and  depress 
brake pedal.  Checlc  that 
selector lever moves freely  from gear to gear. 
With selector  lever  in a gear  position  other than  Park, at- 
tempt  to turn  lkey to off  position  and remove.  Key should not 
go  into off position. 
If  any faults  are found check cable  for lkinks  and 
check 
cable attachment  points  for damage  or faults. 
NOTE- 
* It must only  be possible  to remove ignition ley with 
selector  lever 
in Park position. 
* Do not link shift interlocl( cable.

Driveshaft description 
4 The two-piece driveshaft  is connected  to the transmission  by 
a rubber flex-disc  and to the  rear final drive  by a constant ve- 
locity (CV) joint. 
A universal joint  is used  at the center  of the  driveshaft  and 
the  shaft  is supported in  the middle  by a center support 
bearing.  The bearing is mounted  in rubber  to isolate vibra- 
tion. 
- The  rear constant velocity joint  compensates  for fore and 
aft  movement  of the  drive  line. 
Troubleshooting 
The source  of driveline vibrations and noise can be  difficultto pin- 
point. Engine, transmission,  rear axle, or wheel vibrations  can be 
transmitted through  thedriveshaftto the car body. Noises from 
thecar may  be caused  by final drive problems,  or by  faulty  wheel 
bearings, drive axles,  or even 
wom or improperly inflated tires. 
NOTE- 
For  drive axle repair  information,  see 331 Final Drive 
Driveshaft noise or vibration may  be caused by worn 
ordam- 
aged components.  Check the universal joint for play. With  the 
driveshaft  installed, pull  and twist the driveshaft while watch- 
ing the  joint. The 
BMW specification for  play is very small,  so 
almost any noticeable play  could indicate a problem. 
Check  the torque  of the  fasteners  at the  flange connections. 
Check  the rubber  of the  flex-disc and center bearing  for dete- 
rioration or tearing. Check the driveshaft for broken or miss- 
ing balance  weights. The weights  are welded  tabs on the 
driveshaft tubes.  In addition to inspecting for faulty driveshaft 
parts,  the installed  angles of the driveshaft should also  be 
considered.   
						

							
1 Driveshaft 
Further inspection requires removal  of the  driveshaft. Checlc 
the front centering guide  on the transmission output flange  for 
damage or 
misalignment. Also  check runout at the  transmis- 
sion output fiange and output shaft,  and at the  final drive  input 
fiange. Check  the bolt hole bores in the flange  for wear  and 
elongation.

Spin  the driveshaft center bearing  and 
check ior smooth  op- 
eration without play. Check the constant velocity joint 
forwear 
or play.  Checlc the universal joint for wear or binding.  If it  is 
difficult  to move or binds,  the driveshaft section should  be 
replaced.

Maximum allowable  0.15 
mm (0.006 in.) 
NOTE- 
With  the driveshaft installed, the  actual amount  that the drive- 
shaftjoint  pivots is limited.  For the most  accurate  test, check 
joint 
in its normal  range of movement. 
If inspection  reveals nothing wrong with  the driveshaft,  it may 
need to  be rebalanced.  This can be done  by a speciality drive- 
shaft repair shop. Also, 
checlc driveshaft alignment as  de- 
scribed  below. 
NOTE- 
Minor driveshaft  vibrations can often  be corrected  simply by 
disconnecting  the driveshaft  at the  final  drive  and reposition- 
ing it go, 180 or 270 in relation  to the final drive  input 
flange. 
The  troubleshooting table below lists symptoms 
oi driveshaft 
problems and their  probable causes. Most of the  repair  infor- 
mation  is contained within this repair group. There  are refer- 
ences  to other repair groups, where applicable.
