P07A5 - Direct clutch Transmission direct clutch stuck on. Ratio based test. The clutch control bypass valve (multiplex valve) exhausts the direct clutch when the valve is in the compressed position, where SSD points in the low/reverse position, the diagnostic can isolate the direct clutch stuck on from SSB stuck on because getting 3rd gear when 1st gear commanded, the clutch control bypass valve is in the spring compressed position indicates that SSB cannot be the cause.
  • Customer may notice slow acceleration from stop. May be in 3rd gear when 1st gear is commanded.
  • Once the DTC is stored, 3rd and 5th gears are only available.
  • Erratic shifting, harsh engagements, poor launch performance.
  • Will turn on wrench lamp.
 See DIAGNOSIS BY SYMPTOM .
P07A8 Low/reverse clutch Transmission low/reverse clutch performance/stuck off. SSD is multiplexed through the clutch control bypass valve (multiplex valve) to the low/reverse and overdrive clutch, the diagnostic can isolate the low/reverse clutch failed off from SSD stuck off when the overdrive clutch applies normally and the low/reverse clutch did not.
  • Customer may notice no reverse.
  • Disable 1st gear.
  • Delayed engagement into drive.
  • Poor launch performance due to 2nd gear launch.
  • Will turn on wrench lamp.
 See DIAGNOSIS BY SYMPTOM .
P07A9 P0767 Low/reverse clutch Transmission low/reverse clutch stuck on. SSD is multiplexed through the clutch control bypass valve (multiplex valve) to the low/reverse and overdrive clutch, the diagnostic can isolate the low/reverse stuck on by turning off SSE, If the transaxle shifts into 4th when the clutch control bypass valve moves SSD is stuck on, but if the transaxle stays in 1st then the low/reverse is stuck on.
  • Low/reverse clutch failed on.
  • One-Way Clutch (OWC) transmits torque in both directions.
  • Stuck in 1st gear.
  • Will turn on wrench lamp.
 See DIAGNOSIS BY SYMPTOM .
P07AA - Overdrive clutch Transmission overdrive clutch performance/stuck off. SSD is multiplexed through the clutch control bypass valve (multiplex valve) between the low/reverse and overdrive clutch, the diagnostic can isolate the overdrive clutch failed off from SSD stuck off when the low/reverse clutch applies normally but the overdrive clutch is stuck off.
  • Overdrive clutch failed off.
  • Disable 4th, 5th and 6th gears.
  • Reverse may be delayed or disabled.
  • High engine rpm.
  • Will turn on wrench lamp.

P0867 - Transmission hydraulic and clutch systems Transmission fluid pressure. The control valve test raises line pressure to insure that the clutch control bypass valve (multiplex valve) is latched, then turns on SSE to test for a stuck TCC control valve under steady state operation in 4th, 5th and 6th gear. If the ratio breaks away the test is aborted. If enough ratio break away occur, the DTC is set.
  • Multiplex latch pressure inadequate (valve moves when SSE turns on).
  • Overdrive clutch pressure issue.
  • Line pressure issues.
  • Solenoid regulator valve issues.
  • Customer may notice flairs during test.

P1636 - PCM Inductive signature chip communication error. Lost communication with solenoid driver.
  • The solenoid driver is an internal PCM chip that controls the solenoids. The main microchip communicates with the solenoid driver over a serial interface, sending out the desired solenoid state and receiving back a circuit fault status.
  • If communication is lost with the solenoid driver, the solenoid states become unknown, so the control system forces the transaxle solenoid power control relay off.

P072E P072E, P073A or P072E, P073A, P0757 Direct Clutch System Faults SSB failed on. The codes:
  • P072E stuck in 3rd gear.

  • Non-electrical failures where SSB (direct clutch VFS) is stuck on (pressure).
  • Direct clutch regulator valve stuck in spring compress position.
  • Customer may notice a vehicle deceleration on a shift into 2nd, 4th or 6th gear (direct clutch failing to release will cause a tie-up in these gears).
  • Customer might notice a harsh 1-3 shift.
  • Customer might notice erratic shifting while the test is confirming direct clutch is failed on.
  • After a code is stored, ail gears but 3rd and 5th gears are disabled.
