ZF, DSG and PDK service, adaptation and spec-correct fluid changes.
Industrial City, Riyadh, Saudi Arabia
An automatic gearbox on a modern European car packs mechanics, hydraulics and electronics into one unit. Its behaviour changes gradually before it fails: a slight delay on engagement, a jolt at one specific shift, hesitation on deceleration. These are readable signals, and correct service usually solves them long before a full overhaul becomes necessary.
Transmission fluid is what protects the internals. Changing it on time with the right specification prevents most costly failures; neglecting it slowly damages clutch packs and mechatronics.

These are readable signals, and correct service usually solves them long before a full overhaul becomes necessary.
Transmission fluid carries hydraulic pressure, cools the unit and sets clutch friction. With heat and time it degrades and carries metal debris into the valve body. In Riyadh's climate the effect of a delayed change is very visible. Our change is not a drain and fill: we drop the pan, replace filter and gasket, clean the magnets, then fill the calculated volume at a controlled temperature, because a wrong level causes overheating or pressure loss.
Jolts and delays do not always mean internal damage. Many cases originate in the mechatronics: internal valve leakage, an electrical connector wicking fluid into the unit, or adaptation values that drifted over time. We read line pressures, fluid temperature and adaptation values during a road test, and that separates a contained repair from a full teardown.
A vibration at a steady 60–100 km/h often relates to the torque converter lock-up clutch, and is frequently confused with wheel imbalance or engine mounts. We separate them with a guided road test and data logging: watching converter slip and the lock-up point, and checking whether the vibration follows engine speed or road speed. Correct diagnosis here saves you a large, unnecessary job.
A change in shift feel is the first thing a driver notices; early attention prevents wider damage.
If your case is close to one of these descriptions, send it as is on WhatsApp and we will understand it immediately.
Practical notes learned from cars that came through the workshop, useful even if you never visit us.
We record the symptoms, history and vehicle data.
We measure and test before suggesting parts.
We explain the cause and work before starting.
A specialist carries out and documents the work.
Final checks and a road test where needed.
Each marque has its own gearbox and service routine; details sit on the marque page.
A fault may cross more than one system, so we connect the inspection to the most relevant services.
Clear written commitments from diagnosis to handover.
The warranty scope is stated on the invoice; if the same symptom returns during it, the car is checked without a new diagnostic fee.
You receive the fault, parts and labour report before dismantling or replacement begins.
Replaced parts remain available until collection and are shown to you clearly.
Inspection readings, work, date and mileage are recorded so the next visit is faster and more accurate.
Practically no, especially in Riyadh heat. We recommend periodic changes based on use.
If the jolt is tied to a shift point or a specific speed it is usually the transmission; a road test with live module data confirms it.
Sometimes yes if the case is early and clean; sometimes inspection shows internal wear needing more work. We tell you before you spend.
We separate fluid, mechatronic and torque-converter faults using data and a road test before deciding on repairs.
Tell us whether the harsh shift occurs cold or hot and in which gear; send a cluster video if possible and the last fluid-service date.
We read pressure, temperature, adaptation and slip values, then run a controlled road test rather than relying on feel alone.
We explain whether the case needs specification-correct fluid service, mechatronic repair or internal work, with the cost of each path.
We complete required adaptations and verify shifts, temperature and leaks in a documented final test.
Tell us exactly when the jolt or delay appears — it shortens diagnosis a lot.
