BMW 6 Series automatic gearbox repair for grand tourers
Few garages see many 6 Series gearboxes, so a specialist who does is a real advantage.
The 6 Series has been fitted with a ZF 6-speed automatic on the E63 and E64, an 8-speed on the F06, F12 and F13, and an 8-speed on the G32 Gran Turismo. The M6 used different transmissions, including a 7-speed SMG and later a dual-clutch.
Because 6 Series cars are typically lower-mileage but older, the faults are often age-related: ageing seals, tired fluid and valve body wear, along with sensor and software issues. Convertibles that sit for long periods also bring their own problems.
We repair and rebuild 6 Series 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 6 Series has.
Why use a BMW 6 Series gearbox specialist

Our BMW gearbox specialists have the diagnostic experience to find the real fault rather than trial and error with expensive parts. Call 0808 164 0418 to speak to a gearbox specialist about your BMW 6 Series.

Understanding the BMW 6 Series gearboxes
A 6 Series can have a conventional Steptronic or something far more specialist, so it helps to know which.
The ZF automatic
Most 6 Series cars use a ZF torque converter automatic. It is smooth and strong, and the faults are the usual ones: valve body wear, solenoids and converter shudder.
On low-mileage cars, age is often the issue, with seals and fluid deteriorating even though the clutches look fine.
- Hard engagement
- Gear hunting
- Shudder at cruise
SMG and dual-clutch units
The M6 used a hydraulic SMG on early cars and a dual-clutch gearbox later. Both are performance-focused and sensitive to use and maintenance.
Faults include pump and actuator wear, clutch wear and mechatronic problems, and honest advice depends on how the car has been used.
- Long shift delays
- Clunk into gear
- Hydraulic pump noise

Common BMW 6 Series gearbox problems
BMW 6 Series gearbox problems are often age as much as mileage. The symptoms below cover the usual ones.
BMW 6 Series automatic gearbox slipping
If the 6 Series revs rise but the car does not respond, clutches are slipping. On a low-mileage car it can follow degraded fluid and ageing seals. Ring 0808 164 0418 as soon as you notice it.
BMW 6 Series gearbox juddering
Judder at low speed or at a steady cruise on a 6 Series can come from the converter or, on an M6, from clutch or actuator wear. Describe it to a specialist on 0808 164 0418.
BMW 6 Series gearbox warning light
A gearbox or drivetrain warning on a 6 Series means a fault is stored. Reading the codes is the first step, and replacing parts without them is the expensive way to guess. Call 0808 164 0418 and we will explain what the codes are likely to mean.
BMW 6 Series limp mode
A 6 Series in limp mode limits power and gears to protect the gearbox. It often follows a sensor, solenoid or pressure fault. Call 0808 164 0418 before you drive any further.
Hard engagement after standing
A bang or delay when you select Drive after the car has sat overnight.
Gear hunting on a gentle incline
The gearbox changes up and down repeatedly instead of holding a gear.
SMG pump or actuator noise
On M6 cars, a long whirr or delay as the hydraulic system builds pressure.
