Here's a link I found claiming there is no steering wheel lock on Automatic Transmission vehicles:
'The steering wheel lock mechanism in the column (automatic transmission vehicles), was eliminated in July 2002 however the change still complies with NHTSA requirements. The mid year change affected some 02 models, and all 2003-2006 domestic PT's. Additional model year changes are available through the Pit area on the site.'
