Low Transmission Fluid: For both manual and automatic transmissions, the primary cause for whining when in gear is low transmission fluid. If the fluid is too low, then the internal components of the transmission are not lubricated properly.

If you notice your car making a grinding sound when it accelerates, your issue is likely to do with your transmission, a problem with your differential, a bad wheel bearing, a damaged CV joint, or a worn engine/motor mount.

If your car is hesitating when you try to accelerate, then it might be time to change your fuel filter. Over time, the filter can become clogged with dirt and debris. This can make it difficult for the car to get the fuel it needs to run properly.

Owners of the model year 2007-2010 Honda CR-V also have several complaints regarding the transmission. Examples are that the transmission is faulty and the vehicle shudders in low gears, the vehicle will not shift out of park, and the vehicle stalls and accelerates and decelerates on its own.

Whining and howling

Whining that appears relatively suddenly and becomes very loud over short period of time can be indicative of damage to the gear teeth or gear hub bearings. The most likely source of this damage is a shortage of lubrication.

Should the whining noise of your transmission continue whenever your vehicle is in gear, this can mean there is a problem occurring in your torque converter. Check to see if the noise desists when you shift the vehicle to park or neutral. A constant whining noise when your car is in gear needs professional attention.

A loud noise coming from your vehicle when you accelerate, particularly one that sounds similar to a lawn mower is most likely due to an exhaust system leak.

A squeaking or squealing sound when you`re accelerating or cruising can mean there`s a problem with a drive belt on the engine. You should get this checked as soon as possible. Slapping noises when accelerating usually mean a tyre is flat or under-inflated.

The most common reasons a Honda CR-V makes noise when braking are bad brake pads, bad brake rotors, or bad brake caliper.

A humming or whining noise in an automatic transmission vehicle often means that you are low on automatic transmission fluid. If this is the case, you want to refill that fluid immediately. Transmission fluid reduces friction, which means heat, which in turn is bad news for transmissions.

Strange Noises

If the sound resembles humming, buzzing, or clunking, you may be experiencing transmission failure. Bad automatic transmissions may emit humming, buzzing, or whining noises while manual transmissions have harsher “clunking” sounds.
