CVT, DCT & Automatic Transmission Repair
Shuddering on acceleration, a whining gearbox, or a transmission warning light — our technicians diagnose and repair CVT, dual-clutch, and automatic transmissions on European and Japanese vehicles, without the cost of a full replacement.

Signs your transmission needs attention
CVTs are built for smooth, stepless efficiency, but a handful of failure points show up again and again once the fluid ages or a component wears past tolerance.
Overheating
The most common failure mode — usually driven by heavy load or fluid that’s degraded past its service life.
Shudder & jerking on acceleration
A shaking or juddering sensation when pulling away or accelerating is one of the most frequently reported complaints.
Slipping belt or chain
The belt or chain that transfers power inside a CVT can slip or wear out under high torque or extended use.
Whining or grinding noise
Unusual noise from the gearbox is often the earliest audible sign of internal wear.
Valve body & sensor faults
Electronic valve body failures and gear slippage caused by sensor or control-module faults are common alongside mechanical wear.
Repair first. Replace only when we have to.
We specialize in ZF, DSG, and mechatronics systems as repair experts — not a replacement shop. Most of the faults above can be fixed at the component level, which costs a fraction of a full transmission swap.

- →Targeted repairsJerky shifting, gear slippage, and clutch wear are diagnosed and fixed at the source, not solved by swapping the whole gearbox.
- →Component-level fixesDual-clutch (DSG/S-Tronic) pack replacement, and repair of mechatronics solenoids and TCMs.
- →Precision maintenanceManufacturer-spec fluid flushes and system adaptations to restore the transmission’s original shift behavior.
Diagnose
Full scan and road test to isolate whether the fault is mechanical, hydraulic, or electronic.
Fluid & adaptation
Manufacturer-spec fluid change paired with a system adaptation — resolves a large share of shifting complaints on its own.
Component repair
If internal parts have failed, we remove the transmission and replace the specific broken component rather than the whole unit.
Keep it from happening again
Two habits account for most of the CVT failures we see in Dhaka traffic and heat.
Change the fluid on schedule
Using the exact manufacturer-specified CVT fluid, changed on schedule, prevents most of the faults above and significantly extends transmission life.
Ease off harsh driving
Avoiding aggressive towing and rapid acceleration reduces heat buildup and belt stress — the two biggest drivers of early failure.
Frequently Asked Questions
| Can a CVT gearbox be repaired instead of replaced? | In most cases, yes — belt, valve body, sensor and fluid-related faults are repaired at the component level rather than requiring a full transmission swap. |
| How much does a CVT diagnosis cost? | Diagnosis pricing depends on the make and symptoms — message us on WhatsApp with your car’s details for an accurate quote before any work begins. |
| Do you repair DSG and dual-clutch gearboxes? | Yes — DSG, S-Tronic and other dual-clutch transmissions are one of our core specialties, including mechatronic unit and clutch pack repair. |
| Where is the workshop located? | MRB Auto Solution is based in Basundhara R/A, Dhaka. |
