BMW M5 automatic gearbox repair for the high-performance saloon
The M5 asks more of its gearbox than almost any BMW, which is why honest advice matters.
The E60 M5 used a 7-speed SMG III, a hydraulic sequential gearbox. The F10 M5 moved to a 7-speed M dual-clutch gearbox, and the F90 uses an eight-speed M Steptronic, a ZF-based automatic, with xDrive.
SMG cars suffer from pump and actuator wear along with clutch wear. Dual-clutch cars suffer from clutch wear and mechatronic faults. The F90 is robust, but high torque and tuning still take their toll.
We repair and rebuild M5 gearboxes with OEM-approved parts, and every repair carries a 12-month parts and labour guarantee. Call 0808 164 0418 with the registration and we will tell you which gearbox your BMW M5 has.
Why use a BMW M5 gearbox specialist
An M5 gearbox repair is not a job for trial and error. A BMW gearbox specialist knows these units, is honest about their condition and tells you what torque and tuning have done. Call 0808 164 0418 to speak to a gearbox specialist about your BMW M5.
Common BMW M5 gearbox problems
BMW M5 gearbox problems are largely about torque and heat, and the symptoms differ by generation.
or call 0808 164 0418
BMW M5 automatic gearbox slipping
Slip under full power is the classic M5 symptom, the revs soaring while the car fails to respond, and it is often heat related. Ring 0808 164 0418 as soon as you notice it.
BMW M5 gearbox juddering
Judder on an M5 can be clutch judder on a dual-clutch car or actuator wear on an SMG. On an F90 it is more likely the converter. Describe it to a specialist on 0808 164 0418.
BMW M5 gearbox warning light
A gearbox or drivetrain message on an M5 means a code is stored. SMG hydraulic warnings in particular should be taken seriously. Call 0808 164 0418 and we will explain what the codes are likely to mean.
BMW M5 limp mode
An M5 in limp mode limits power and gears. It can follow a hydraulic, mechatronic or sensor fault. Call 0808 164 0418 before you drive any further.
Long hydraulic whirr
On SMG cars, a prolonged pump noise before each shift.
Missed gears under load
The gearbox fails to find the next gear on hard acceleration.
Smell of hot clutch
A burning smell after a hard run or launch.

Understanding M5 SMG, dual-clutch and M Steptronic
High power is the common thread, and each gearbox copes in its own way.
The E60 hydraulic gearbox
The SMG III is a sequential gearbox using hydraulics to operate the clutch and shift gears. It is fast but wears at the pump, actuator and clutch.
A hydraulic whirr that lasts longer than it used to is a classic early warning.
- Long pump whirr
- Delayed shifts
- SMG warning
Power and the clutches
With around 500 or more horsepower, any M5 puts heavy load through its clutches. Heat builds, and clutch life depends on use.
Tuning increases this further. We repair tuned cars and advise honestly.
- Slip under power
- Clutch smell
- Missed gears
Which gearbox does your BMW M5 have?
Only certain M5 generations had an automatic or semi-automatic gearbox. Give us your registration and we will confirm.
7-speed SMG III
Hydraulic pump, actuator and clutch wear.
7-speed M dual-clutch
Clutch wear, mechatronic faults and fluid issues.
ZF 8-speed M Steptronic
Young cars with sensor or software issues. Torque and tuning increase wear.
