Automatic gearbox specialists

Is your gearbox making a grinding noise?

A grind under load, on a change, or all the time. Metal on metal does not heal. Automatic grind is our work. A pedal manual is not.

  • A grind that arrived with a bang?
  • Worse in one gear, or whenever you pull away?
  • Three pedals, and you are not sure if we can help?

Grinding is damaged gears, a failed bearing, or a dual-clutch that is trying to apply a half-dead pack. On an automatic that is specialist work. On a manual, we will say so.

A grind is late. Debris is already in the oil. Stop and call while the car still moves.

What is a gearbox grinding noise?

Quick answer

A grinding noise from an automatic gearbox is often a worn planetary gear set or gearbox bearing, or a clutch pack dragging, and it can follow earlier whining. On a dual-clutch it can be a shaft bearing or a dragging pack. Grinding means metal is wearing, so stop driving and get the unit diagnosed.

On an automatic gearbox a grind is often a planetary gear set or a gearbox bearing that has gone beyond a whine. On a dual-clutch it can be a pack dragging or a shaft bearing.

A diagnostic check and an oil sample tell us if the unit can be rebuilt or is finished. Limp mode with a grind is the computer and the metal agreeing.

Count the pedals. Three is a manual. We do not repair those. Two is automatic or dual-clutch. Ford, Volkswagen and BMW two-pedal cars are regulars in the bay.

*Service4Service does not repair manual gearboxes. A grinding three-pedal car needs a manual specialist. Two-pedal automatics and dual-clutch units are the work we do.

Key facts
  • Grinding is usually advanced wear, beyond a whine
  • Metal on the pan magnet or in the fluid confirms internal wear
  • A fluid sample helps decide between repair and rebuild
  • Manual gearbox grinding is not work Service4Service takes on

Grinding means metal is already in the oil

How a grind starts

A whining noise that was ignored becomes a grind when teeth or a bearing shed. Low automatic transmission fluid starves the mesh.

Once you can hear grit, the honest conversation is rebuild versus replacement, after a look inside or a proper test.

1

Noise starts as a whine

Bearings or gears.

2

It becomes a grind

Metal is loose.

3

Drive fades

Stop. It only gets worse.

FAQs

Straight answers from a transmission specialist.

Usually, if it follows gear or road speed. Wheel bearings growl differently. We listen.

Yes, once gears or bearings are damaged. It is a late sign.

No.

If it is low, a leak is the issue. Oil will not glue teeth back on.

Sometimes, if the case is sound. Diagnosis first.

No. Recover it.

Grinding usually means metal parts are wearing against each other, such as a bearing, a gear set or a clutch pack that will not release. It can also come from a damaged torque converter or flexplate at the front of the gearbox.

Yes, though it is less typical than in a manual. Grinding on a change can come from a failing clutch pack, damaged gear set or hydraulic problem, so stop and have the car diagnosed instead of waiting to see if it settles.

Often yes, if the casing and main parts are sound, but metal debris spreads through the unit, so a full strip and clean is needed. A fluid sample and inspection after diagnosis show whether a rebuild is realistic.
