The Body Control Module (BCM) is one of the most important electronic components in the VT and VX Commodore. Acting as the vehicle’s central body electronics controller, the BCM manages everything from central locking and interior lighting to the security system, keyless entry, and communication between various vehicle modules. As VT and VX Commodores continue […]
Tailshaft vibration is a common driveline problem affecting VT, VX, VY, and VZ Commodores. It can range from a minor vibration felt at highway speeds to a severe shudder that affects vehicle comfort and drivability. Because the Commodore uses a rear-wheel-drive layout with an independent rear suspension (IRS), the tailshaft, centre bearing, universal joints, differential, […]
A sagging roof lining is one of the most common cosmetic problems affecting VT, VX, VY, and VZ Commodores. Even well-maintained vehicles eventually suffer from roof lining failure as the original foam backing deteriorates with age, heat, and exposure to sunlight. The problem often starts with a small section of loose fabric around the rear […]
Power steering problems are a common issue affecting VT, VX, VY, and VZ Commodores. As these vehicles age, components such as the power steering pump, steering rack, hoses, seals, and fluid reservoirs begin to wear, leading to leaks, noise, heavy steering, and poor steering performance. Fortunately, most power steering faults develop gradually and provide warning […]
Regular transmission servicing is one of the most important maintenance tasks for VT, VX, VY, and VZ Commodores. Whether equipped with the 4L60E automatic transmission, 4L65E, 5L40E, or a manual gearbox, proper servicing can significantly extend transmission life, improve shift quality, and help prevent costly repairs. Many transmission failures occur because the fluid becomes contaminated, […]
Steering rack leaks are one of the most common power steering problems affecting VT, VX, VY, and VZ Commodores. As these vehicles age, the seals within the steering rack begin to wear, allowing power steering fluid to escape. If left untreated, a small leak can eventually lead to heavy steering, power steering pump damage, and […]
Differential problems are a common issue affecting VT, VX, VY, and VZ Commodores, particularly vehicles with high kilometres, towing history, performance modifications, or neglected servicing. The independent rear suspension (IRS) used in these Commodores provides excellent ride quality and handling, but it also places significant demands on the differential and its mounting components. Over time, […]
The VY and VZ Commodore are widely regarded as some of Holden’s best-balanced rear-wheel-drive vehicles. With independent rear suspension (IRS), improved ride quality, and refined handling compared to earlier models, they remain popular daily drivers and project cars. However, as these vehicles age and accumulate kilometres, suspension wear becomes increasingly common. Worn bushes, leaking shocks, […]
Lowering a VY or VZ Commodore is one of the most popular suspension modifications among Holden enthusiasts. It improves stance, reduces body roll, and enhances handling when done correctly. However, improper lowering can lead to ride quality issues, tyre wear, and suspension damage. This guide explains the best lowering methods for VY and VZ Commodores, […]
Automatic transmissions, which are found in most modern vehicles, are sophisticated systems designed to automatically change gears based on speed, load, and throttle input. While many of the components in an automatic transmission system are electronically controlled today, there are still some mechanical elements that play a crucial role in the transmission’s operation. One such […]
