SERVICE INFORMATION

Condition:

Transmission indicator light may be on and DTC P1870 is set in the PCM (Powertrain Control Module).

Possible Cause:

Improper torque of the main case bolts permitted the adapter plate gaskets to slip out of position. The out of position gasket created an internal hydraulic pressure leak that created low fluid pressure to the lockup clutch.

Correction:

Follow the procedures in this bulletin to replace the adapter plate gaskets.
