Condition
Some owners may comment that the transmission range selector is difficult to move/shift.
Cause
The original shift cable may be binding and/or allowing too much friction to build up within the cable sheathing and the internal cable.
Correction
Replace the shift cable, P/N 12454863, and the brake transmission interlock solenoid (BTSI), P/N 26064467, with a new design on the 1998 model
Buick Century as instructed below. For 1999 models, replace only the transmission shift cable with P/N 12458110.

Open the hood, install fender covers to the vehicle.
2.
Set the parking brake, block wheels and with the key in the OFF position, put the transmission lever in neutral.
