WORK SAFELY! For maximum safety, perform this installation on a clean, level surface and with the

engine turned off. Installation of this shifter requires working underneath vehicle. Raise front of

vehicle by lifting at points specified by the vehicle manufacturer. Place blocks or wedges in front of

and behind both rear wheels to prevent movement in either direction. DO NOT USE A BUMPER

JACK FOR SUPPORTING VEHICLE.

CAUTION: To avoid any possibility of bodily injury or damage to vehicle, do not attempt installation

until you are confident that the vehicle is safely secured and will not move.

IMPORTANT

1. All adjustments must be made with shifter and transmission in “Park”, “Neutral”, and “Low” gear

positions.

2. Adjustments are critical and must be precise.

3. Do not mix components (all parts including shifter cable must be genuine Hurst components

provided with kit).

4. If a shifter is removed and re-installed, adjustments must be checked and re-adjusted, if necessary.

5. When routing cable avoid sharp bends. Provide large full loops (if needed) for smooth shifting and

long cable life. Avoid routing cable near exhaust pipes as heat from the exhaust system will melt

cable casing. (Permanent damage of cable will result).

6. Always check cable for freedom of movement before connecting to shifter and transmission control

arm.

Failure to comply with any of the above may result in malfunction of shifter operation. Damage

to cable due to sharp bending, kinking, or excessive heat is not covered by Warranty.

These instructions detail the installation of the Hurst Quarter Stick Shifter for GM Powerglide 2 speed

transmission with both forward and reverse pattern valve bodies and GM Turbo TH 350/400 3 Speed

transmission with a reverse pattern valve body only. Please refer to the specific instructions for your

particular application for detailed information. See the illustration on page 4 for changing from 2

speed to 3 speed operation.

The shifter can be mounted directly to the floor with the four sheet metal screws supplied.

5. If necessary, mark and cut a slit in the carpet to accommodate shifter cable. Using a hole saw or other suitable tool, make a 1-1/2” diameter hole in flooring 3” in front of forward mounting hole and 13/4” to the left of forward mounting hole to accommodate shifter cable (See Figure 1). For some vehicles the 3” dimension may be less. Deburr hole with a file and sand with emery cloth. Install rubber grommet into 1-1/2” diameter hole. 6.

GENERAL MOTORS Turbo-Hydramatic 350 and 400 1. Remove backdrive linkage rod and stock transmission arm from gear selector shaft on transmission using a 9/16” socket and replace with Hurst transmission arm PT. 1058561 re-using stock bolt or nut. Transmission arm must be installed with round hole down and bend in arm positioned away from transmission. (See Figure 4).
PAGE 5
3. Remove tape from cable and re-install rubber boots. Place shifter cable into mounting bracket on transmission oil pan and secure using two (2) internal tooth lockwashers and two (2) 7/16” hex nuts supplied with cable. 4. Be sure shifter is in “Neutral” position. Check and be sure transmission arm on gear selector shaft is also in “Neutral” position. Thread cable pivot onto end of shifter cable. Adjust cable pivot until it slides freely into hole in transmission arm.
PAGE 6
FORD C-4 & C-6 1. The stock backdrive linkage that locks shifter stick in “Park” position cannot be retained. Linkage rod lever (located inside engine compartment on steering column) must be secured in the upward position. This will allow ignition key to be turned to “Lock” position and withdraw freely out of lock. 2. Remove linkage and lever that is connected to the downshift lever shaft. Shift linkage rods should be disconnected and discarded.
PAGE 7
C-6: Two (2) transmission oil pan bolts at the left rear corner must be removed to install the Hurst cable bracket and two (2) spacers. Install the cable bracket onto the oil pan using the 5/16”-18 x 3/4” bolts (supplied). (See Figure 6C). If transmission has a cast aluminum oil pan, spacers may not be necessary. Figure 6C 5. Remove tape from cable and re-install rubber boots.

2. Locate wire connected to starter solenoid terminal marked “S” and trace to original equipment neutral start switch. Locate wire connected to “Solenoid” terminal of ignition switch and also trace to original neutral start switch. Disconnect both wires leading to original equipment switch and connect to Hurst neutral/park start switch wire leads. Use correct size insulated electrical butt connectors to properly connect the wires together. (Refer to Figure 8).
PAGE 9
Applications 1969-Later The original equipment factory back-up light switch is located on the transmission. No additional wiring necessary. SHIFT INDICATOR LAMP SOCKET WIRING CONNECTION Use a suitable length of 22 gauge insulated automotive grade wire (not supplied). Strip 1/4” of insulation off each end of wire.

STARTER MOTOR AND BACK-UP LIGHT TEST OPERATION We recommend disconnecting the “batt” wire from distributor so engine will crank but not start. Reconnect negative (-) battery cable. With the shifter in “Park” position and brake pedal pressure applied, test starter motor operation in every gear position of the shift pattern. The starter must operate in “Park” and “Neutral” gear positions ONLY.

It must operate in “Park” position ONLY. It is very important that the column lock be adjusted correctly so that when shifter is placed into “Park” position, ignition key can be turned to “Lock” position. Steering wheel should lock and key should withdraw freely out of lock.
