Parts for your 2019 Holden Commodore-Thrust bearing

2019 Holden Commodore thrust-bearing: is it even a thing?

Short answer: a clutch-style thrust bearing isn’t fitted to the 2019 Holden Commodore (ZB). Holden’s MY19 Commodore range in Australia and New Zealand was automatic-only — 9‑speed GM Hydra‑Matic units on the petrol models and an 8‑speed Aisin automatic on the diesel — so there’s no manual clutch, and therefore no clutch thrust/release bearing to service or replace. This is confirmed across Holden’s MY19 specification sheets and owner’s manual for the ZB Commodore, along with GM technical overviews for the Hydra‑Matic 9‑speed family and Aisin’s AF50‑8 automatic, all of which use a torque converter rather than a manual clutch pack.

When people say “thrust-bearing” for a passenger car, they usually mean the clutch release (throwout/thrust) bearing that presses on the clutch diaphragm spring in a manual gearbox. Because the ZB Commodore runs a torque converter automatic, that part doesn’t exist in the driveline. The torque converter takes care of drive take-up and damping, and the transmission’s internal hydraulics and clutch packs manage gear changes — no clutch pedal, no release bearing.

It’s worth noting there are thrust-type bearings elsewhere in any modern powertrain, such as the engine’s crankshaft thrust washers/bearing surfaces and internal thrust bearings within the automatic transmission. However, these are internal components and not treated as routine service items. They’re addressed only during an engine or transmission overhaul if wear limits are exceeded — not something listed in regular servicing for a 2019 Commodore.

So, if someone’s searching for a “2019 Holden Commodore thrust-bearing”, they’re likely thinking in manual-transmission terms. For the ZB, the practical advice is different: keep the automatic serviced per the manufacturer’s schedule, use the specified transmission fluid, and investigate any shudder, flare, or unusual driveline noise promptly. Those symptoms can point to torque converter, fluid, mount, or ancillary pulley issues — but not a failed clutch thrust bearing, because the car doesn’t have one.

• GM Hydra‑Matic 9‑speed technical literature (torque converter automatic)
• Aisin AF50‑8 automatic transmission documentation (torque converter automatic)

Popular questions

Does a 2019 Holden Commodore have a clutch thrust/release bearing?
No. The ZB Commodore was sold with automatic transmissions only, so there’s no manual clutch assembly and no clutch thrust/release bearing to replace or maintain.

What noises could be mistaken for a failed thrust bearing on a ZB Commodore?
Owners sometimes report noises at idle or under light load and assume “clutch bearing”. On the ZB, it’s more likely to be torque converter shudder, an accessory belt idler/tensioner, or a pulley bearing. Less commonly, a driveline mount or AWD component (on V6 AWD models) can transmit vibration.

Are there any thrust bearings in the engine or transmission at all?
Yes, but they’re internal. The engine uses crankshaft thrust bearing surfaces, and the automatic transmission contains thrust elements. These aren’t scheduled service items, they’re only assessed during major repairs or rebuilds if wear or endfloat is out of spec.
