CONSOLE SHIFT WON'T DISENGAGE FROM PARK

VEHICLES AFFECTED: 1986 ELDORADO AND SEVILLE

Some 1986 Eldorado and Seville models may experience a condition which prevents the transmission from being disengaged from "Park".

To correct this condition, the following procedure should be followed:

1. Remove shifter handle by removing the handle retaining clip (Figure 1, Items 1 and 2) and pulling the handle upward.

2. Remove the part lock detent rod (Figure 1, Item 3) and insert a new detent rod P/N 1643023 in the shift control (Figure 1, Item 4).

3. With the shifter in the "Park" position, install the gauge over the new detent rod and cut the rod off flush with the top of the gauge.

4. Using a fine grit sandpaper or emery cloth, dress the cut end until it is square and smooth, removing any ridge lines resulting from the cutting operation.

NOTE: Top of rod must be cut squarely and be free from burrs and/or taper. Each rod must be sized to the specific shift control in which it is needed.

5. Clean any debris found on the rad or in the control tube and lubricate the detent rod using a white non-corrosive lubricant and install the rod in the control tube.

6. Replace the handle assembly with the appropriate part number listed on the attached chart (Figure 2).

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
