The 203 full time 4-wheel drive transfer case is the only one on which linkage adjustment is possible.

  1. Place the selector lever in the cab in the Neutral position.
  2. Detach the adjustable rod ends from the transfer case levers.
  3. Insert an 11 / 64 in. drill bit through the alignment holes in the shifter levers. This will lock the shifter in the neutral position with both levers vertical.
  4. Place the range shift lever (the outer lever) on the transfer case in the Neutral position.
  5. Place the lockout shift lever (the inner lever) on the transfer case in the unlocked position. Both levers should now be vertical.
  6. Adjust the rods so that the linkage fits together. The indicator plate can be moved to align with the correct symbol.
  7. Remove the drill bit.
