P0795: Pressure Control Solenoid C
What to do
If exactly one gear change has become bad while everything else is unchanged, that specificity is the point — say which change it is. It usually indicates one solenoid rather than a transmission that is wearing out.
What this code means
A fault in the third pressure control solenoid. By the time a transmission carries three of them, each major clutch is being metered more or less independently — the arrangement usually called clutch-to-clutch shifting, where one element is released and another applied under separate pressure control rather than relying on one-way clutches to manage the handover.
That design is why these transmissions shift as smoothly as they do, and it is also why a single pressure control fault produces such a specific complaint. Only the shifts that use this solenoid are affected; everything else remains exactly as it was. A gearbox with one consistently bad change and nothing else wrong is characteristic of this family of codes, and worth recognising as a narrow fault rather than the beginning of a general decline.

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.
