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
– 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 notes
Start by inspecting the transmission fluid level and condition, and change fluid if necessary.
When is the code detected?
Transmission in second gear and the ECM detected an incorrect gear ration
Symptoms
– Engine Light ON (or Service Engine Soon Warning Light)
– Incorrect transmission shifting
– Incorrect transmission shifting
P0732 FORD 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.
