Transmission
The gearbox: solenoids, speed sensors, torque converter. For half of these codes the first move is cheap — the fluid level and condition and the transmission connector on the outside.

What it usually turns out to be
- Fluid level and condition is the first move for almost every code in this group.
- Solenoids stick because of dirty fluid far more often than they die.
- The code itself usually lives in the transmission unit: an ordinary scanner only sees the flag that it exists.
