What Does Resetting the Transmission Module Do? How and When to ResetBad connections could affect the module and cause transmission issues. Reverting the TCM to its factory settings could eliminate the problems they caused.
P0729 Code: Gear 6 Incorrect RatioNewer vehicles often have more than four gear ratios for better fuel economy. The control modules also determine when to shift up or down between gears depending on various data, such as throttle position and vehicle speed.
Why Do EVs Have Fake Engine Noise?EVs and internal combustion engine vehicles generally use powertrain data to make the sound emulate the increasing pitch of engine revs and the drops in tone during a gear shift.
Is Your Car Stuck In Neutral? Here’s WhyThe transmission fluid is also responsible for performing these duties:
Transferring power in the torque converterProviding hydraulic pressure in clutches and servosLubricating bearings, bushings, and gearsTransferring heat to cool transmission partsProviding the correct friction for clutch and band operation
P0700: Transmission Control System (MIL Request)The TCM monitors the sensors and actuators in the transmission system and sends the data to the PCM. This module monitors the throttle speed sensor, motor speed sensor, and output shaft speed sensor. Once the module detects something wrong with the transmission controls, it’ll trigger the P0700 code.
P0763 Code: Shift Solenoid C ElectricalTo change gears, the automatic transmission uses bands and clutches, which are activated by having fluid pressure in the right place at the right time. Transmission solenoids are in charge of opening and closing valves in the valve body to allow transmission fluid to flow to the clutches and bands.
