Cause

Restricted transmission fluid filter

The filter inside the transmission blocked enough to starve the pump. Starvation shows as low pressure, which reads as a failing pump or worn clutches — and what blocked the filter is usually clutch material, so the finding matters as much as the fix.

Typically a moderate job.

2 of the 12 codes this can cause indicate a fault where continuing to drive risks damage or is unsafe. Which one you have matters more than the cause does — read the code's own page before deciding.

Codes where this is a likely explanation first, rather than merely a possible one.

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:

The car — make, model, year and engine. The same fault behaves differently on each.
What you measured, not only what you replaced.
What actually fixed it — or that nothing did, which is worth knowing too.
