When I put it in reverse it will not Move

Hi and thanks for using 2CarPros.

First, make sure the fluid is clean and full.

Next:

There are shift solenoids on the transmission and if they fail, you can lose reverse, have issues with hard shifting or even gear binding.

Now, when the vehicle is placed in reverse, solenoid C should not get power and B should. See picture 4 for location. If that isn't happening, the transmission can't shift into reverse. I attached a picture of the B and C solenoids for you to see. What I need you to do is disconnect solenoid C and test if you have reverse. To help, shift solenoid B will have a black connector and C will be brown. If anyone has removed these solenoids for some reason, they could have mixed them up by accident. They will both fit in both locations. If you do get reverse and no one removed the solenoids, replace the solenoid.

If this isn't the problem, here are directions for adjusting the shift linkage. Make sure the linkage is in the correct position.

SHIFT CABLE ADJUSTMENT
Adjustment

1. Start the engine. Shift to reverse to see if the reverse gear engages. If not, refer to Troubleshooting.
2. With the engine off, remove the console.
3. Shift to [N] position, then remove the lock pin from the cable adjuster.

4. Check that the hole in the adjuster is perfectly aligned with the hole in the shift cable.

NOTE: There are two holes in the end of the shift cable. They are positioned 900 apart to allow cable adjustments in 1/4 turn increments.

5. If not perfectly aligned, loosen the locknut on shift cable and adjust as required.
6. Tighten the locknut.
7. Install the lock pin on the adjuster.

NOTE: If you feel the lock pin binding as you reinstall it, the cable is still out of adjustment and must be readjusted.

8. Start the engine and check the shift lever in all gears. If any gear does not work properly, refer to troubleshooting.

If neither of these issues help, the following items can be the cause and it will need to be seen by an expert.

NO REVERSE

1. Servo shaft sticking.

2 . Defective reverse gear.

3. Defective 4th clutch.

Let me know if this helps or if you have other questions.

Take care,
