The only type of shifter used is a floor mounted type.


WARNING
On all types of transmissions, never hammer or force a new shift knob on with the shifter installed, as the plastic bushing connected to the lever will be damaged and cause hard shifting.

Proper adjustment of the shaft linkage is dependent on both the position of the shift levers at the transmission and the length of the shift rods. The shift levers, rods and bearing block are all located underneath the floor tunnel; the driveshaft shield may have to be removed to gain access to them.

  1. With the transmission in neutral and the driveshaft shield removed (if so equipped), remove the clip locks and disconnect the shift rods from the intermediate shift levers under the floor shift bearing bracket.
  2.  
  3. With the shifter still in the neutral position, lock the three intermediate shift levers by inserting a 0.2156 in. rod (a No. 3 drill bit will do, or any other tool of approximately the same diameter) through the levers and the holes in the bearing bracket.
  4.  
  5. Check the positioning of the shift levers at the transmission (see illustrations). Adjust by loosening the clamp bolts and moving the levers.
  6.  
  7. With the intermediate levers locked and the shift levers adjusted properly, try hooking the shift rods back onto their respective intermediate levers. The shift rods may be adjusted by loosening the locknut and turning the ball socket on the end until they are the proper length.
  8.  

When hooking up the shift rods to the intermediate levers, be very careful not to move the transmission shift levers out of their adjusted position.

When reattaching the shift rods on 190 models, use only clip locks which have a radiused edge. If the old style clip locks with a square edge are used, there is a possibility that the locks will pop out and the shift rods will drop down.

  1. Remove the locking rod from the bearing bracket, start the engine and then shift through the gears a few times. Occasionally slight binding may call for VERY slight further adjustments.
