P1DB7 on Jeep

Torque converter clutch performance fault stored by the transmission computer on Jeep and Chrysler vehicles

Severity not verified — if the car runs badly, have it inspected

Stellantis links the code to a check engine light and possible transmission fluid overheating, and owners report jerking and stalling, but we found no source on how long it is safe to drive.

It gets more serious if:

  • Inspect soon: The transmission jerks on take-off, stalls or the fluid overheats.
