P0700 00 MIL request from Transmission Control (TC) Modul

When the P0776 OBD-II trouble code is set, the Powertrain Control Module (PCM) has detected a problem with the Transmission Pressure Control Solenoid "B". Most automatic transmissions incorporate at least three solenoids that are solenoid A, B and C. The trouble codes related to the "B" solenoid are codes P0775, P0776, P0777, P0778 and P0779. The code set is based on the specific malfunction that alerts the PCM and illuminates the Check Engine Light. The purpose of the Transmission Pressure Control Solenoids is to control the pressure of the fluid for the proper operation of an automatic transmission. The PCM receives an electronic signal based on the pressure within the solenoids. An automatic transmission is controlled by bands and clutches that change gears by having fluid pressure in the right place at the right time. Based on the signals from associated devices monitoring the speed of the vehicle, the PCM controls the pressure solenoids to direct fluid at the appropriate pressure to various hydraulic circuits that change the transmission gear ratio at the correct time. The code P0776 is set by the PCM when the Pressure Control Solenoid "B" is not functioning properly or stuck in the "Off" position. E

Causes for this P0776 transmission code may include: Defective Pressure Control Solenoid Dirty or contaminated fluid Dirty or clogged transmission filter Defective Transmission Pump Defective Transmission Valve Body Restricted hydraulic passages Corroded or damaged connector Faulty or damaged wiring Faulty PCM
