ANSWERS TO YOUR QUESTIONS
Transmission faults manifest through characteristic signs: abnormal metallic noises during gear shifts, excessive vibrations under load, or difficulty engaging gears.
Progressively harder gear changes indicate wear on the synchronizers. Oil leaks around seals or on housings reveal deterioration of sealing components.
Sudden engine speed fluctuations without an actual gear change or constant slipping under load signals major failures in clutches or planetary gearsets on automatic gearboxes.
Repairing transmissions for PL/TP vehicles is possible in 80% of cases thanks to modern reconditioning techniques. Specialized workshops handle bearing, synchronizer, and shaft replacements on manual gearboxes from major European brands.
The overhaul process includes careful disassembly followed by component inspection. Wear parts such as seals, rings, and bearings are systematically replaced with new or reconditioned components.
Ultrasonic cleaning of housings removes metal residues, preserving the longevity of repaired transmissions. Test bench validations ensure repair quality, guaranteeing optimal reliability for your construction equipment.
Replacing a gearbox on construction equipment requires between 8 and 12 hours of workshop time, depending on the model's complexity. Automatic transmissions for heavy trucks may need up to 16 hours for complete removal and reinstallation.
Our optimized organization allows quick handling of your equipment. Codimatra technicians schedule interventions around your operational constraints, minimizing downtime.
Preliminary diagnostics significantly speed up repairs by accurately identifying components to be replaced. Our parts stock guarantees immediate availability of essential transmission elements.
Repair costs for gearboxes vary depending on the nature of the work. A full overhaul of a manual transmission represents an investment of 3,000 to 4,500 euros, including replacement of wear components.
Restoring an automatic gearbox for TP requires a larger budget, ranging from 5,000 to 15,000 euros. Our permanent parts stock allows significant cost optimization.
Used gearboxes for construction equipment and heavy trucks represent an investment depending on the models. Automatic transmissions from major brands like Volvo, ZF, or Allison fall at the upper end of the price range, while reconditioned manual gearboxes offer a more economical option.
