TRANSMISSION CONTROL MODULE

Do not interchange Transmission Control Modules with previous year transmission control modules. If a same year TCM is being used from a different vehicle, the following procedures must be performed:

  • Quick Learn Procedure
  • Electronic Pinion Procedure

The Transmission Control Module is located on the right fender inner panel, in the engine compartment. It is held in place by four mounting screws.

NOTE: If the Transmission Control Module has been replaced, the following procedures must be performed:

  • Quick Learn Procedure: This procedure will allow the transmission control module to learn the characteristics of the vehicle.
  • Electronic Pinion Factor Procedure: This procedure will reprogram the TCM to compensate for different tire sizes and final drive ratios.

Would the codes relate to transmissiom problem or controller problem. Everthing is original no swap out. Chrysler have had a "limp home mode" for years for certain problems.

Symptom:

P1776-SOLENOID SWITCH LATCHED IN L-R POSITION

When Monitored and Set Condition:

P1776-SOLENOID SWITCH LATCHED IN L-R POSITION

POSSIBLE CAUSES

CHECKING SYMPTOMS AND POSSIBLE CAUSES

LOW BATTERY VOLTAGE CAUSING SYMPTOM

TRANSMISSION PAN HAS EXCESS DEBRIS

DEBRIS IN PAN CAUSED VALVE BODY DAMAGE

INTERMITTENT CODE P1776

I would have the transmission serviced fluid and filter changed and see if that solves the problem..First check the battery condition. just because it starts dont mean that the battery is good it should be load tested. any auto parts store will do this for you free.
