WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

Possible Component		Reference/Action
210 - ROUTINE
Transmission Fluid
	Incorrect level	CHECK the transmission fluid level. ADJUST transmission fluid to correct level. REFER to TRANSMISSION FLUID LEVEL CHECK .
	Transmission fluid filter and seal assembly - plugged, damaged	INSTALL a new transmission fluid filter assembly. REFER to FLUID PAN, GASKET AND FILTER .
Selector Lever Linkage Damaged or Incorrectly Adjusted
	Selector lever cable	INSPECT and REPAIR as required. VERIFY selector lever cable adjustment. REFER to AUTOMATIC TRANSAXLE/ TRANSMISSION EXTERNAL CONTROLS . ADJUST selector lever cable as necessary.
Powertrain Control System
	PCM electrical inputs/outputs, external vehicle wiring harnesses, main control molded leadframe, Transmission Range (TR) sensor, Shift Solenoid A (SSA) or Line Pressure Control (LPC)	If DTCs are set, CLEAR the DTCs. CARRY OUT the Key ON Engine OFF (KOEO) and Key ON Engine Running (KOER) self-test. ROAD TEST the vehicle and CHECK for DTCs. If the DTCs return, GO to PINPOINT TEST A . If engine control DTCs return, REFER to ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) (SECTION 0) .
	Multiple shift missing (more than one gear)	If some shifts are missing, DETERMINE which shifts do not occur. REFER to CLUTCH AND SOLENOID APPLICATION CHARTS . MONITOR appropriate PIDs as listed in Diagnostic Parameters Identification (PID) Chart.
Main Control
	Leadframe - contamination	REMOVE the main control assembly, REFER to MAIN CONTROL . INSPECT and CLEAN the shift solenoid terminals on the main control molded leadframe for metallic contamination, REFER to SHIFT SOLENOIDS (SS) . CLEAR the DTCs. ROAD TEST the vehicle. If the symptom returns, GO to PINPOINT TEST A .
	Defective clutch (A) regulator valve	INSPECT main control assembly for stuck valves or contamination. REFER to MAIN CONTROL .
	Defective clutch (A) latch valve	INSPECT main control assembly for stuck valves or contamination. REFER to MAIN CONTROL .
	Defective clutch (B) regulator valve	INSPECT main control assembly for stuck valves or contamination. REFER to MAIN CONTROL .
	Defective clutch (B) latch valve	INSPECT main control assembly for stuck valves or contamination. REFER to MAIN CONTROL .
	Defective clutch (C) regulator valve	INSPECT main control assembly for stuck valves or contamination. REFER to MAIN CONTROL .
	Defective clutch (E) regulator valve	INSPECT main control assembly for stuck valves or contamination. REFER to MAIN CONTROL .
	Defective clutch (E) latch valve	INSPECT main control assembly for stuck valves or contamination. REFER to MAIN CONTROL .
Clutch Plates
	Forward clutch (A) friction and steel plate - failure or Low One-Way Clutch (OWC) assembly - failure	For 1st, 2nd, 3rd or 4th gear concerns, INSPECT the forward clutch assembly for damage. REPAIR as required. REFER to FORWARD CLUTCH ASSEMBLY . For the One-Way Clutch (OWC), INSPECT for damage. One-Way Clutch (OWC) must rotate counterclockwise and lock clockwise. REFER to TRANSMISSION - EARLY BUILD or TRANSMISSION - LATE BUILD .
	Direct clutch (B) friction and steel plate - failure	For 3rd or 5th gear concerns, INSPECT the direct clutch assembly for damage. REPAIR as required. REFER to DIRECT CLUTCH ASSEMBLY .
	Intermediate clutch (C) friction and steel plate - failure	For 2nd or 6th gear concerns, INSPECT the intermediate clutch assembly for damage. REPAIR as required. REFER to INTERMEDIATE CLUTCH ASSEMBLY .
	Overdrive clutch (E) assembly - failure	For 4th, 5th or 6th gear concerns, INSPECT the overdrive clutch for damage. REPLACE the overdrive clutch. REFER to OVERDRIVE CLUTCH ASSEMBLY .
