The Renault PK6 is a heavy-duty 6-speed manual transmission developed for higher-torque passenger and light-commercial vehicle applications. It uses cable-operated gear selection, hydraulic clutch actuation and an integrated differential, with numerous application-specific versions identified by a three-digit PK6 suffix.
Specification: 6-speed manual • Renault PK6 • Transverse installation on most applications • Cable-operated gear selection • Hydraulic clutch operation • Fully synchronised forward gears • Integrated differential • Multiple gear-ratio and final-drive configurations • Approximately 2.7 litres oil capacity on documented versions • 75W-80 transmission oil on applicable versions.
The PK6 is fitted across selected Renault, Nissan and Vauxhall/Opel applications, including Laguna II, Espace IV, Avantime, Vel Satis, Trafic, Vivaro and Primastar, as well as the rear/mid-engine Clio V6. Ratios and components vary significantly by suffix, so the VIN, complete gearbox code and individual component identification should always be confirmed before ordering replacement parts.
Common Faults
Common PK6 problems include shaft-bearing wear, synchroniser wear, selector mechanism problems, differential wear and gear damage. Symptoms can include gearbox whine or rumbling, difficult or crunching gear changes, excessive shaft movement and drivetrain noise.
Diagnosis should include oil level and condition, shaft bearings, gears, synchronisers, selector components, differential and clutch operation before the gearbox is dismantled.
