Gearbox teardown, internal repair, rebuild and adaptation.
Industrial City, Riyadh, Saudi Arabia
A gearbox rebuild demands operating-theatre cleanliness and precisely specified parts. A single leftover metal particle can lodge in a valve and undo the whole job. So we separate stripping and washing from assembly, and replace every wearing item instead of reusing it.
Once a gearbox is damaged internally, a fluid change will not help. We remove it, inspect and photograph the internals, then agree what gets replaced before rebuilding.
A gearbox rebuild demands operating-theatre cleanliness and precisely specified parts. A single leftover metal particle can lodge in a valve and undo the whole job. So we separate stripping and washing from assembly, and replace every wearing item instead of reusing it.
Before rebuilding we rule out simpler causes: fluid level and condition, internal mechatronic leakage, drifted adaptation values, or a sensor fault. We measure line pressures, log data on a road test, and analyse what sticks to the pan magnets — the type of debris itself indicates which component is wearing. Many cases are solved without a full strip, and we tell you plainly when that is the case.
The unit is fully stripped, parts washed and checked visually and by measurement: clutch packs, seals, pistons, bearings and valve body spools. The complete gasket and seal set is replaced, the valve body cleaned or replaced by condition, and the torque converter inspected and replaced when needed — refitting a tired converter to a rebuilt gearbox brings the problem straight back.
Assembly follows specified torques and measured clearances, then the unit is filled with the correct fluid at the right temperature. After fitting we reset adaptation values and run the on-road learning procedure until shift points settle, then re-read pressures and temperatures to confirm. The car is handed over after a real road test, not just an idle run in the bay.
We try the lighter fixes first and only strip the unit when tests demand it.
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.
Gearbox types differ by marque in build and service; details on their pages.
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.
Yes — module programming and adaptation reset are needed for smooth operation after repair.
Yes in some cases — mechatronics or a specific clutch pack — and internal inspection after teardown decides that.
Yes — resetting adaptation values is necessary after internal work so shifts stay smooth and matched to the new condition.
We prove the fault is internal before removal, then document parts, clearances, cleaning and adaptation after installation.
Report affected shifts, cold/hot behaviour and any earlier fluid service or repair; avoid driving with severe slipping.
We test codes, pressure, mechatronics, torque converter and fluid to confirm the issue is not external or software-related.
We dismantle, clean, measure and document frictions, bushes, valves and replacements before torque-controlled assembly.
We perform adaptation and learning and monitor pressure, temperature and shifts on a road test, with follow-up instructions.
Tell us the age, mileage and current behaviour and we'll lay out the options.
