A gearbox that refuses a gear, a slipping clutch, a gearbox that goes into fault mode: the truck is immobilised. As a partner of the ZF [pro]Service network, we diagnose, repair and programme automated manual, manual and automatic gearboxes.
LNVI workshop · Le Blanc-Mesnil (93)On a truck, an automated gearbox is driven by a control unit and operated by air and actuators. A refused gear shift often comes from a sensor, an actuator, insufficient air pressure or a lost learning procedure, not from the internal mechanics. We measure before removing: the gearbox is only removed if the diagnosis justifies it.
We read the fault codes and parameters, check the air supply and control, then test the gear shifts. The gearbox is only removed if the diagnosis justifies it.
As a partner of the ZF [pro]Service network, we work with the manufacturer's procedures.
A method that avoids removing a gearbox for nothing, and refitting it without having set it up.
Fault codes, parameters and history of the gearbox control unit.
Air pressure and quality, actuators, sensors and wiring harnesses.
Gear shifts, clutch, behaviour when hot and cold.
Replacement of the faulty component or reconditioning of the gearbox, with original or equivalent parts.
Programming and learning with the diagnostic tool, in-house.
Test under real conditions before the vehicle is handed back.
A truck gearbox is expensive. These are mistakes we do not make.
A faulty sensor or actuator gives the same symptoms as an internal failure. We measure before removing.
After a new clutch or actuator, a gearbox that has not been re-learned shifts poorly and wears the clutch.
Water or oil in the air circuit damages the control. We check the air dryer at the same time.
Worn or unsuitable gearbox oil shortens the life of the synchronisers. We follow the manufacturer's recommendations.
Trucks and vans of all makes. For ZF gearboxes, the manufacturer's procedures.
Diagnosis, actuators, control, learning and programming.
Synchronisers, selector forks, bearings, sealing.
Electronic diagnosis, oil change, actuators, programming and learning.
Disc, pressure plate, release bearing, control, adjustment and flywheel check.
Programming and learning of control units with the diagnostic tool, in-house.

Our Le Blanc-Mesnil workshop welcomes trucks from all over Île-de-France. Do you manage a fleet ? One file per vehicle, the quote before work starts, online progress with #TrackYourTruck, the report and photos by email.
Yes. We diagnose the control, actuators and sensors, we repair, then we carry out the learning and programming in-house.
Yes. LNVI is a partner of the ZF [pro]Service network.
No. Removal is only decided after the diagnosis. Many failures come from the control, the air or a lost learning procedure, and are repaired without removal.
Yes: disc, pressure plate, release bearing and control, followed by the gearbox learning procedure when it is automated.
Always. Diagnosis first, then the itemised quote, and nothing is committed without your written approval.
Give us the plate number and the symptom. We will tell you when the vehicle can come in.
We have been working with this garage for years and there has never been the slightest problem. Very professional team, top notch!
Hugues K.A team at your service. Quality work in record time. Deadlines are always perfectly met.
Pascal M.Exactly the kind of partner we needed. The service is very fast and lives up to our requirements.
