  1. Not going into gear

Although manual transmission is generally less problematic, there are some key indicators that something needs to be fixed. Trouble getting the vehicle into gear when the clutch is pressed is an indication that something is wrong.

This can happen when you try to get into first gear or at any other point during gear shifts.

Some common causes of this include:

Low transmission fluid

wrong transmission fluid

Adjustment needed in the shift cable or clutch linkage

  1. Burning Smell

Smelling a burnt odour usually relates to transmission fluid and is a serious sign that all is not well. Such an odour is usually caused by overheating of the transmission, which is required to keep important bits of the system lubricated and prevent burning. This is a serious problem and some of the transmission unit includes a mini-radiator to prevent the system from overheating.

  1. Slipping gears

If the transmission is functioning correctly it should stay in the gear selected until you or the automatic gearbox changes it. Slipping teeth can occur when the car suddenly slips into neutral.

This is a potentially dangerous situation as a slipped gear transmission will no longer get the power to the wheels so it is very difficult to control the car. If this ever happens is very important that you take the car to a specialist as soon as possible. For Iveco Daily Gearbox, visit a site like, leading suppliers of the Iveco Daily Gearbox.

  1. Transmission Fluid Leaks

Leaking transmission fluid is very easy to identify and is a clear indication that there is a problem. Automatic transmission fluids are important components of your vehicle’s ability to shift gears and leakage can be a big problem.

  1. Grinding / Shaking

Manual and automatic transmission reacts differently when there is a problem. In a manual vehicle, grinding or shaking can occur when shifting gears – probably caused by clutch wear.

  1. Whining, clunking or humming

Hearing noises that don’t sound right or normal is an indication that your transmission needs to be examined. The sound will differ depending on the vehicle type but you know your vehicle better than others and will notice when something does not sound right.

Automatic transmission can present with a whimper, humming or buzzing sound when there is a problem.

Manual transmission may present with sudden noises and mechanical sounds. Clunking noises when shifting gears is a red light and you must take your car to a specialist as soon as possible.

  1. Unresponsive

When you select a gear, it should respond immediately and stay there until you change it. However, if there is hesitation or an inability to get into gear, this is a warning that something is wrong with the transmission. In a manual transmission, if after shifting into a new gear, the vehicle revs but does not respond and move quickly, then there is a possibility of clutch wear or something more serious.
