Initial service of the column shift type shift lever assembly requires starting with an on-car examination to check smooth movement of the P to R positions when the ignition is ON and the brake pedal is depressed while validating forward movement in D and reverse movement in R. Check the installation of park/neutral position switch assembly as well as the shift lever assembly when problems occur. The service requires disconnecting the negative battery cable for at least 90 seconds before removing the front door scuff plates as well as the cowl side trim board and lower instrument panel finish panel and instrument panel safety pad insert and steering pad and steering wheel assembly and both steering column covers. The installer should detach the turn signal switch assembly including spiral cable sub-assembly then remove the column shift assembly by unconnecting the transmission control cable and harness. The column shift requires disassembly with the removal of shifting bellcrank assembly, compression spring, shift lever plate sub-assembly, lock release link, lever subassembly, shift lock solenoid and transmission control switches for P and S positions. Check the column shift lever subassembly while evaluating its resistance level then readjust the shift lever alignment if required. Installation must begin with the transmission control switches while the assembly process requires secure connection of the shift lock plate and solenoid and lever subassembly at the correct torque levels. The last step involves installing the column shift assembly and turn signal switch assembly and steering components and negative battery terminal reconnection while systems operating after reconnection initiation may be necessary.
