Shift Lever

REMOVAL & INSTALLATION



See Figure 1

Most vehicles covered by this guide utilize a 2-piece shift lever assembly. The upper portion of the shift lever is threaded to the lower portion and locked in position using a jamnut. If equipped, the upper portion may be removed without unbolting the rest of the shifter lever/housing from the top of the transmission housing. In fact, on most later model vehicles, the shift lever housing cannot, or should not, be removed with the transmission installed. On some transmissions, such as the New Venture Gear 3500 the shift lever is retained to a shift lever socket inside the transmission using a roll pin. On vehicles equipped with a 1-piece lever, the entire assembly (shift lever/lever housing) must be removed from the transmission as a unit.

  1. Position the transmission in Neutral, this will prevent stressing the internal shift forks when working on the shift lever components.

  1. Unthread the shift knob and nut (if equipped) from the top of the shift lever. The nut is usually used as a jamnut to hold the shift knob in position, so knob removal may be easier if you turn the nut slightly to ease tension from the knob before attempting to unthread it. This will most likely mean turning the nut clockwise to thread it further down on top of the shift lever.

  3. If equipped with a shifter boot retainer, loosen and remove the retaining screws.

  5. Remove the shifter boot along with the retainer (if equipped).
  6.  

On most models covered by this guide, there is a locknut (jamnut) at the base of the shift lever (where the lower portion of the shift lever enters the transmission housing). This locknut is used on 2-piece shift levers; if removal of only the upper portion is desired, it may be unthreaded from the lower portion at this time.

  1. On models equipped with a 2-piece shift lever, hold the lower locknut from turning and use the wrench slots in the base of the upper shift lever to unthread and remove it from the vehicle. If removal is difficult, it is advised that you back the nut off of the upper lever by turning it clockwise, then unthread the lever by turning it (the lever) counterclockwise.

  3. If equipped with a 1-piece lever, loosen and remove the retaining bolts. Carefully remove the shift lever/housing from the transmission housing assembly.
  4.  

To install:
  1. If equipped with a 1-piece lever, clean the gasket mating surface taking care not to allow debris inside the transmission. Lightly lubricate the shifter with moly grease, then install the assembly to the top of the transmission using a new gasket or silicone sealer (as applicable). Install the retaining bolts and tighten to 10 ft. lbs. (13 Nm).
  2.  
  3. If equipped with a 2-piece lever, thread the locknut all the way on to the base of the lower shift lever (do not tighten it), then thread the upper shift lever to the lower portion. Secure the upper lever by holding the lever using the wrench slots and tightening the locknut up against the base of the upper lever. Tighten the locknut to 35 ft. lbs. (48 Nm).
  4.  
  5. Install the shifter boot along with the retainer (if equipped). On vehicles equipped with a boot retainer, install and tighten the bolts.
  6.  
  7. If equipped with an upper locknut, thread the nut all of the way onto the top of the upper shift lever, but do not tighten it. Thread the shift knob onto the lever, then turn the knob as necessary to align the shift pattern. Hold the knob aligned as desired, and tighten the jamnut against the knob to retain the position.
