DTC P0732: A/T 2ED Gear Function: Description: Notes

WARNING: This page is about a different car, the 2003 Infiniti I35. However, it is still accessible from the selected car via links, so may be relevant.

This malfunction will not be detected while the A/T CHECK indicator lamp is indicating another self-diagnosis malfunction.
This malfunction is detected when the A/T does not shift into second gear position as instructed by the TCM. This is not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such as control valve sticking, improper solenoid valve operation, etc.
