Transmission noise is also a type of transmission malfunction. The root cause of transmission issues is often high temperatures, as excessive heat can degrade the quality and lubrication performance of transmission fluid, increasing friction and wear. Additionally, sludge can form inside the transmission, impeding its operation. Extended Information: Abnormal noises can also stem from poor performance of related components in the vehicle's drivetrain, including the clutch, transmission, and driveshaft. Diagnosing vehicle noise issues requires on-site test driving to listen and assess, combined with analyzing the conditions under which the noise occurs, its characteristics, and source for an accurate judgment.

I've been pondering the clicking noise in low gears while driving for quite some time. The most common culprit is the clutch release bearing - when you press the accelerator, the stressed bearing tends to make noise, sounding like metallic squeaking. Worn gears or faulty synchronizer rings in the transmission can also cause this, especially in older vehicles. Another possibility is loose flywheel bolts rattling around. Ignoring these issues will only make them worse. The most reliable solution is to have a skilled mechanic inspect it on a lift, checking everything from chassis bolts to transmission fluid. Don't hesitate to replace what's needed - it's not worth skimping on repairs.

Last time my car had the same issue, there was always a clunking noise from the chassis when starting in first gear or accelerating in second gear. It's most likely due to the aging transmission mount bushings—cracked rubber can't contain the engine's vibrations. Worn CV joints can produce similar noises, especially more noticeable when turning. For cars with modified exhausts, also check the exhaust hangers; loose bolts can cause resonance noises. First, inspect the engine bay for any obviously loose components. Use a pry bar to test the play in the control arms and CV joints. If you can't pinpoint the problem, it's best to take it to a shop to read the fault codes. Transmission system issues are not to be taken lightly.

Gear grinding noises require focused checks in three areas. Worn clutch discs slipping will produce a metallic clanging sound, like frying pans colliding. For manual transmissions, loose shift cables may cause the gear lever to vibrate. Damaged differential gears create more serious issues, sounding like sand tumbling in a metal can. Diagnose by warming up the engine, engaging the parking brake, shifting to neutral, and having an assistant rev the engine while you locate the noise source - engine bay and chassis produce distinct sound directions. Develop good habits: drive gently during cold starts and change transmission fluid regularly, with 50,000 km being the critical replacement interval.
