Subject: | High Effort Required to Turn Ignition Key and Remove Shift Lever
from Park Position (Replace Transmission Shift Control Cable Assembly and
Fasteners) |
Models: | 2000 Chevrolet Impala |
Condition
Some owners of vehicles that have the transmission shift lever mounted
on the steering column may comment that they have difficulty removing the
transmission shift lever from the park position. In addition, some may also
comment that it takes a high amount of effort to rotate or turn the ignition
key.
Cause
The steering column mounted transmission linear shift control cable
that attaches to the ignition switch may be too long and may also be routed
incorrectly.
Correction
Replace the steering column mounted transmission linear shift control
and cable assembly with a new assembly that has a shorter cable and an adjustment
feature. Use the following service procedure for installing and adjusting.
For additional information and fastener torque specifications, see
the Steering Column sub-section in the Steering section, and the Instrument
Panel sub-section in the Body and Accessories section of the appropriate Service
Manual.
