I have a Lumina (S), model 2006. Its a 3.6lit V6.
Whenever I start the engine while its cold, there is a loud***** sound. Makes me feel like something is gonna break or may b some pipe is loose and comes in contact with something to make such a sound.
It only happens when the engine is cold.
The sound is similar to a plastic pipe hitting on a concrete wall.
I feel that it comes from under the hood only or somewhere from the gear box.
the engine is as good as it should be, havnt got any problem with engine. Its great.
Could this be a transmission/gear box problem?
have the same problem?
