Symptom Chart: Automatic Transmission

Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to: Diagnostic Methods .

In most circumstances the PCM sets a DTC to help guide with diagnostics. Refer to the DTC Chart before using the Symptom Chart.

Symptom	Possible Sources	Action
Engagement Concerns	No Forward	Forward clutch damaged or worn. REFER to: Forward Clutch Assembly .
No Reverse		Direct clutch damaged or worn. REFER to: Direct Clutch Assembly . Low/Reverse clutch damaged or worn. REFER to: Low/Reverse Clutch Assembly .
Harsh Reverse		Direct clutch damaged or worn. REFER to: Direct Clutch Assembly . Damaged center support. REFER to: Low/Reverse Clutch Assembly .
Harsh Forward		Forward clutch damaged or worn. REFER to: Forward Clutch Assembly . Damaged center support. REFER to: Forward Clutch Assembly .
Delayed/Soft Reverse		Direct clutch damaged or worn. REFER to: Direct Clutch Assembly . Low/Reverse clutch damaged or worn. REFER to: Low/Reverse Clutch Assembly .
Delayed Soft/Forward		Forward clutch damaged or worn. REFER to: Forward Clutch Assembly .
No Forward and No Reverse		Check the transmission fluid level. REFER to: Transmission Fluid Level Check . PERFORM Transmission Line Pressure Test. REFER to: Transmission Line Pressure Test . Inspect the filter and pump assembly. REFER to: Pump Assembly .
Delayed/Soft Forward and Reverse		Check the transmission fluid level. REFER to: Transmission Fluid Level Check . PERFORM Transmission Line Pressure Test. REFER to: Transmission Line Pressure Test . Inspect the filter and pump assembly. REFER to: Pump Assembly .
Neutral after Launch		Low one-way clutch assembly damaged. REFER to: Low One-Way Clutch Assembly .
Harsh Stop/Start event		Verify Fluid level. REFER to: Transmission Fluid Level Check . If fluid level is ok, Clear any DTC, then carry out prime procedure: Verify TFT is greater than 100 deg.F, prime the Transmission Fluid Auxiliary Pump. Using a diagnostic scan tool, Key ON, Engine OFF, command TRANS_PMP_CMD to 80% for 30 seconds. Carry out a road test until there is a stop/start event. If the restart is harsh, repeat the Transmission Fluid Auxiliary Pump prime procedure. Continue road test and evaluate each stop/start event. Repeat prime procedure until three consecutive normal stop/start events are achieved. Clear DTCs.
Shift Concerns	No 1-2 Shift/Harsh/Soft/Slipping	Intermediate clutch damaged or worn. REFER to: Intermediate Clutch Assembly . Forward clutch assembly damaged or worn. REFER to: Forward Clutch Assembly . Low one-way clutch assembly damaged. REFER to: Low One-Way Clutch Assembly .
No 2-3 Shift/Harsh/Soft/Slipping		Direct clutch damaged or worn. REFER to: Direct Clutch Assembly . Forward clutch assembly damaged or worn. REFER to: Forward Clutch Assembly . Intermediate clutch damaged or worn. REFER to: Intermediate Clutch Assembly .
2-3 Shift Hesitation After A Cold Soak		Verify Fluid level. REFER to: Transmission Fluid Level Check . If fluid level is okay, these hesitation events should be deemed a normal characteristic and do not cause any abnormal wear or durability concern. The hydraulic circuit can partially drain back during an extended engine off condition and could take a couple applications (2-3 shifts) to work any air out of the hydraulic circuit. No further work on the transmission should take place for that condition.
No 3-4 Shift/Harsh/Soft/Slipping		Overdrive clutch assembly damaged or worn. REFER to: Overdrive Clutch Assembly . Forward clutch assembly damaged or worn. REFER to: Forward Clutch Assembly . Direct clutch damaged or worn. REFER to: Direct Clutch Assembly .
No 4-5 Shift/Harsh/Soft/Slipping		Direct clutch damaged or worn. REFER to: Direct Clutch Assembly . Overdrive clutch damaged or worn. REFER to: Overdrive Clutch Assembly . Forward clutch damaged or worn. REFER to: Forward Clutch Assembly .
No 5-6 Shift/Harsh/Soft/Slipping		Intermediate clutch assembly damaged or worn. REFER to: Intermediate Clutch Assembly . Direct clutch assembly damaged or worn. REFER to: Direct Clutch Assembly .
