had frontier 2006 in the shop for parts of 2 days, due to the "clang"
metallic clang sound is heard after car intially started, hot or warm and gears change from 1st to 2nd, sound occurs very loud if engine has been off for 8 hours, less if engine off just a few minutes
the service manager drove with me and heard the "clang" and wrote it up again but when I picked up next day, he said he did not hear sound again
yet, when I pulled off their lot to street, there goes the "clang" again....
it only occurs once per engine start, no sounds when engine running and taking off from a stop sign or traffic lights
suggested to them to check driveplate bolts but no solution found
