How Serious is the Code?

The P2757 diagnostic trouble code is very serious, because it means the torque converter clutch is not able to engage and disengage when it’s commanded to. As a result, a number of drivability issues can happen including slipping, failed gear engagement and engine stalling.

Symptoms

Symptoms of a P2757 include:

  • Delayed, harsh or erratic shifts
  • Slipping through the gears
  • Engine stalling
  • Getting ‘stuck’ in a gear
  • Vehicle won’t move when in gear
  • Decreased fuel economy
  • Transmission overheats
  • Limp mode

Causes

  • Low transmission fluid level
  • Dirty transmission fluid / filter
  • Damaged wiring/connector
  • Transmission fluid leak
  • Faulty torque converter clutch pressure control solenoid
  • Faulty torque converter clutch
  • Faulty torque converter
  • Internal pressure issue
  • Valve body issue
  • ECU or TCM failure

How to Diagnose the Code?

The first thing that should be considered when trying to diagnose a P2757 OBD2 trouble code, is the level and condition of the transmission fluid. The next thing that should be considered is condition of the wiring and connectors on the transmission wiring harness. If all of these things check out, then the TCC pressure control solenoid will have to be tested with a voltmeter.
