Why does my car make a rattling noise when I put it in gear?

What causes rattling noise in transmission?

The cause of rattling and clattering noise is torsional vibration of transmission components that are not under load, that move backwards and forwards within their func- tional clearances. This noise is perceived as distinct from other sources of noise, and is intrusive because of its undesirable character.

What is gearbox rattle?

Rattle noise results from the dynamic behavior of idle gears induced by the fluctuations of the driveline velocity. Under certain operating conditions, the idle gears can vibrate through their functional backlashes. Consequently, rattle noise is mainly related to impacts between gear teeth.

How do I find the rattle in my car?

Start at the side of the car where you hear the rattle. Tap the bottom area of the door with a rubber mallet. If the door rattles, the noise is undoubtedly caused by a loose object lying in the door well. Remove the trim panel to get to the object.

What kind of noise does a bad alternator make?

A common sound made by failing alternators is a very high pitched whining noise that you'll hear when the engine is running. When the RMPs increase, such as when you accelerate, you'll hear the noise get higher in pitch as the pulley spins faster.

Why is my gearbox crunching?

The most likely reason is poor driver technique and perhaps the incorrect gearbox oil. You must NEVER use “Extreme pressure” Hypoid oil in your manual gearbox. If hypoid oil has been used, it will damage the synchro rings, the “Repair” is to remove the EP oil and refill the gearbox with SAE 30 or SAE 15W-40 engine oil!

How much does a gearbox cost to replace?

On average expect to pay between $1000-1500.00 for most reconditioned gearboxes, plus any labour/installation costs to install.
