P0896: Shift Time Too Long OBD-II Trouble Code

When a P0896 DTC is present, it means the ECU has noticed that the transmission is staying in gear for longer than it is supposed to. This can be caused by mechanical or electrical failure, and should be diagnosed by a mechanic as soon as possible.

How Serious is the Code?

A P0896 diagnostic trouble code is only triggered when the computer thinks that the transmission is hanging in gear. This can be caused by something as simple as a shorted wire or corroded connector. But it can also be caused by a failing transmission pump, a sensor, or one of the pressure control components. Needless to say, continuing to drive the vehicle when it is exhibiting the following symptoms and this OBD2 code can result in serious transmission damage and a much higher repair bill.

Symptoms

Symptoms of a P0896 include:

  • Harsh shifts
  • Delayed shifts
  • Erratic up/down shifts
  • Whining noise coming from the transmission

Causes

  • Transmission pump has failed
  • Catastrophic internal mechanical failure
  • Wiring or connector damage
  • Faulty EPC solenoid
  • Transmission pressure sensor has failed
  • ECU has failed or has a programming issue

How to Diagnose the Code?

When diagnosing a P0896 OBDII trouble code, the first step should be to check the manufacturer’s TSB database for known solutions and ECU software updates related to these transmission problems. The transmission fluid should also be checked for a burnt smell/appearance and metal fragments, which can indicate internal component failure. Should everything checked out, the wiring and connectors along the transmission wiring harness should be inspected for signs of damage and corrosion. Any related sensors should be tested as well. Beyond this, internal mechanical inspection will be needed to determine condition of the transmission pump, solenoids and other related components.
