Repair 7

Most cars equipped with an automatic transmission have a feature commonly known as "shift lock," which prevents the driver from shifting out of park when the car is off, when the foot brake isnt applied or when the cars computer senses damage to the engine or transmission. Whatever the situation, sometimes the driver has to override a locked transmission in order to move the car.

Instructions

1

Apply pressure to the foot brake, and turn the engine on.

2

Attempt to shift from park. Sometimes the car rolls backwards during parking, causing the shifter to be slightly stuck, not "locked." If it doesnt budge, its probably the shift lock.

3

Turn off the engine.

4

Search "shift lock" in the index of your Audis manual. Over the years, Audi has used different types of shift locks, two of the most common being an actual button near the shifter, and the other requiring the removal of the plastic panel surrounding the shifter.

5

Depress the shift-lock override button. If the button or mechanism is under the panel that surrounds the shifter, follow your manuals instructions to remove the panel.

6

Shift the car into neutral while still holding or pressing the shift lock override and with pressure still applied to the brake.

7

Turn on the engine while the car is in neutral, and shift into drive or reverse.

The Chrysler transmission bump shift describes a condition when Chrysler transmissions shift harshly from one gear to another when downshifting, for example, from fourth to third or third to second gear. It may be simple to fix or require extensive work.

Causes

In some cases, the wrong type of transmission fluid can cause Chrysler transmissions to bump shift. In other cases, it may be a computer malfunction or a problem with the underdrive clutch.

Fluid Replacement

Changing transmission fluid to one of Chryslers recommended types may be enough to solve some bump shift problems. Sometimes, however, the fluid is only a part of the problem and a more complicated fix is required.

Retraining

Sometimes, Chrysler transmissions with bump shift problems need to have the computer retrained to correctly recalibrate the shift points. This requires disconnecting the battery to erase the computers memory and then repeatedly driving the vehicle with steady throttle position as it accelerates through all four gears, then performing kickdowns -- downshifts caused by pushing the accelerator to the floor -- to help the transmission relearn the correct shift points.

Rebuilding

When the bump shifts in a Chrysler transmission are the result of a problem with the underdrive clutch, changing the transmission fluid or retraining the transmission will not alleviate the problem. In this case, rebuilding the transmission is required.
