Unimatic shifter install

I run mine through a relay so you just need one that can take enough current to drive a relay as finding one that will drive backup lights may be impossible. A small plate holds the microswitch in place.

Again, I used the existing plate as a template. I believe the holes are screw holes which are figging small to thread. Here's a closeup of the backup light switch assembly. It shows the backup cam swivel plate and also you can see the tranny linkage mounting point beneath the roll pin.

That's why the backup cam is smaller then the factory neutral safety cam. Normally the weight of the backup cam, stops the switch from being turned on. During normal driving the cam will bounce up and down depending on the road conditions - I don't like that as it may trigger one of the switches or make a rattle! So I added a torsion spring that wraps around the swivel mount and keeps the cam down.

I did the same for the neutral safety cam. I couldn't find any torsion springs around so I rebent a regular spring into a torsion spring. This is the the drivers side view which is where the backup light switch mechanism is located.

The rear of the car is to the right. It is in the Park position right now. Does it fit my vehicle? Our engineers designed this performance automatic shifter to resemble a manual 4-speed shifter.

Don't let its simplistic look fool you, while it maybe not be as sophisticated or offer all the features of our line of proven race shifters, this unit is just as durable and trouble-free and is backed by our Lifetime Limited Warranty. Includes a shift boot, neutral safety switch, 5-foot Performance shift cable, cable brackets, shift levers and all necessary hardware for an easy installation you can do at home.

Service Parts. Part With a center punch mark the locations of the four mounting bolts. STEP 4. Install the shifter through the hole in the floor from the top. The cable bracket points towards the rear of the vehicle.

If the shifter does not sit flat on the floor, put extra washers between the shifter and the floor as spacers. Tighten the. STEP 5. Check the operation of the neutral safety switch. This step is not necessary on Chrysler transmissions.

The switch should be on when the shifter is in the Park position with the shifter handle all the way forward and in the Neutral position two positions behind Park. The switch should be off in all other positions.

This can be checked with a test light or an ohm meter, or you can probably hear the switch clicking when shifting from Park to Reverse, from Reverse to Neutral and from Neutral to Drive.

If the switch is not operating correctly:. The lever should move up in Park and Neutral and be down in the other gears. If the lever does not move, put a little oil on the pivot.

If when the lever does move, and does not turn the switch on and off, loosen the two screws holding the switch to the shifter by about a half a turn, just enough to move the switch. Move the switch up or down until it operates correctly and then retighten the screws. Do not loosen these screws too much, or the nut plate on the back side may fall off.

STEP 6. Attach the cable to the shifter. The end of the cable with the small fixed hex and the large nut attaches to the shifter. Loosen the locking nut on this end of the cable sheath and slide the cable into the slot on the shifter backing plate See Figure 1. Tighten the locking nut on the cable to 10 lbft. Do not overtighten. STEP 7. Check that the shifter moves through all the gear positions and that the other end of the cable moves in and out.

Route the cable to the transmission as shown in Figure 2 to avoid sharp bends or damage to the cable. For GM and Ford transmissions route the cable to the transmission from the rear. For Chrysler transmissions the cable must be looped around to the front side of the transmission. STEP 8. If you have not already done so, remove the stock selector lever nut and the selector lever.

Discard the stock lever and the stock shifter linkage. Install the stock selector lever nut and tighten securely See Figure 3. The lever must be installed so it can travel its full arc equally in both directions across the center. If the lever is. Use these two holes for THtransmission.

Use other two holes for other GM transmissions. The lever should travel smoothly from front to back with a positive click in each gear position. STEP 9. Remove the two transmission oil pan bolts from the middle of the left side of the oil pan. Install the cable bracket in position See Figure 3.

The bracket must be installed with two spacers between the pan and the bracket. If your transmission is equipped with a cast aluminum oil pan, these spacers should be omitted however the cable bracket may have to be modified.

If your transmission has metric bolts install the two 8mm bolts. Do not overtighten as this can damage the pan gasket. STEP Route the shifter cable according to Figure 2.
