Possible causes

– Low transmission fluid level
– Dirty transmission fluid
– Faulty Shift Solenoids
– Shift Solenoids harness is open or shorted
– Shift Solenoids circuit poot electrical connection
– Transmission mechanical problems
– Transmission hydraulic control circuit

Tech description

Start by inspecting the transmission fluid level and condition, and change fluid if necessary.

– Incorrect transmission shifting

P0732 MITSUBISHI OBD Code Description

This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows:

Torque converter slip ratio = A x C/B

A: Output shaft revolution signal from revolution sensor

B: Engine speed signal from Engine Control Module (ECM)

C: Gear ratio determined as gear position which TCM supposes

If the actual gear position is higher than the position (2nd) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
