A P2706 DTC gets triggered whenever the computer recognizes any malfunction in the operation of the clutch/friction element labeled ‘F’. This could be caused by anything from dirty transmission fluid to a failing solenoid. However letting it go for too long can result in severe transmission damage.
How Serious is the Code?
Having a P2706 OBDII diagnostic trouble code means that the computer has detected a problem with the operation of the friction element/clutch referred to by the TCM as ‘F’. This can be caused by a number of different common transmission problems, such as dirty transmission fluid and failed shift solenoids. All of which can cause serious drivability issues.
Symptoms of a P2706 include:
- Harsh shifts
- Transmission overheating
- Failure to change gears
- Limp mode
- Poor performance
- Poor fuel economy
- Low transmission fluid
- Dirty transmission fluid and/or filter
- Damaged wiring or connectors
- Overheating transmission
- Faulty TCM
- Faulty sensor
- Faulty valve body
- Faulty solenoid
How to Diagnose the Code?
One of the first things that should be done when diagnosing a P2706 DTC, is to check the manufacturer’s TSB database, as there may be a known issue that the factory can help you fix. If no information is found, then the condition and level of the transmission fluid should be evaluated. If it appears to be clean and bright, then the wiring and connectors should be inspected. If nothing is found there, then the valve body, sensors and solenoids should be tested.
What Repairs Will Fix P2706?
- Change the transmission fluid/filter
- Repair transmission fluid leaks
- Repair damage wiring/connectors
- Install new solenoids
- Install new TCM
- Install new valve body
- Install remanufactured transmission
