P0958: Auto Shift Manual Mode Circuit High
What to do
Manual mode will not engage; automatic shifting is unaffected. Nothing about this threatens the gearbox.
What this code means
The manual mode circuit reads above its valid range — an open circuit or a short to supply — which generally means manual mode can never be entered. The transmission shifts automatically as normal and simply declines to hand over control.

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.
