I've had my HHR for a week now. One thing I've noticed is first thing in the morning the transmission whines when moving (LS 5 speed). Once it warms up the noise goes away. Is this normal for this transmission? It's been a while since I've driven a GM manual transaxle but I don't remember them making a whining noise when cold. The air temps here haven't been particularly cold, in the 50's. It seems to be more to do with it sitting overnight.

 

Two things:Are you sure it is the transmission whining? If so,does it whine in all gears or just some? No expert on these particular trans. but an answer could help narrow it to a bearing or gear whine if it is a trans. noise.

 

Yes, it's the transmission. There's no noise until the car moves and the noise is coming from that area. It is gear whine. It sounds like it's in the final drive as the noise changes somewhat with the vehicle speed regardless of gear. It's not a bearing noise.

 

Lack of lube in the transmission?

 

When I refered to bearing,I was talking about transmission bearing.Once again,not an expert on these but I have worked on others that have whined when a tranny bearing was going bad. Sounds like time to take it to the repair shop.Post back what you find. I'm curious as to what you find because I also have a 5 speed(SS w/different trans than LS,LT)
