I was on another Mustang forum and found an article regarding missing bolts on 2005-06 Mustangs. It seems that the two lowest bolts on the manual transmission are missing on hundreds of 05-06 Mustangs. The missing bolts cause the inspection plate to vibrate when starting cold engines. Look under your car and I am sure you will find yours missing too. One guy went to the dealer and complained. The dealer had no time to install "two bolts". The guy said that he would install them. Listen to this ----- The dealer told him it would void his warranty. What BS.
