P2700 Transmission Friction Element A Apply Time Range/Performance OBD-II Trouble Code

The P2700 DTC means that the TCM is having a problem applying one of the friction elements, like a clutch or band. This transmission problem is often related to a lack of hydraulic pressure. However, electrical issues and problems with one of the friction elements can also trigger the P2700 diagnostic trouble code.

How Serious is the Code?

The P2700 OBDII diagnostic trouble code is fairly serious, as it relates to a fault with one of the shifting elements. This transmission problem can also cause major drivability issues, as well as trigger Limp Mode, where the transmission will be locked into a single forward gear.

Symptoms

Symptoms of a P2700 include:

  • Unusually harsh shifts
  • Slipping
  • Failure to change gears
  • Limp mode

Causes

  • Low transmission fluid level
  • Dirty transmission fluid/filter
  • Damaged wiring or connectors
  • Faulty transmission pump
  • Overheating transmission
  • Faulty TCM
  • Faulty sensor

How to Diagnose the Code?

The first thing that should be done when diagnosing a P2700 DTC, is to check the level and condition of the transmission fluid. If it is dirty, then sludge or metal fragments can block the hydraulic passages and prevents the shift elements from working properly. Similarly, transmission fluid leaks can also cause this condition due to a lack of pressure.

Next, the wiring and connectors along the transmission wiring harness should also be inspected for signs of damage or corrosion. If no problems have been found up to this point, then the transmission pump should be inspected. The transmission itself will also need to be carefully examined for signs of of abnormal wear and overheating. The input speed sensor and output speed sensors should also be examined.
