The P0700 code is a generic powertrain code that indicates a malfunction in the transmission control system (TCS). The TCS is responsible for controlling the shifting of the transmission, and it does this by monitoring various sensors and inputs from the engine and transmission. When the PCM detects a problem with the TCS, it will set the P0700 code.
Symptoms
The symptoms of the P0700 code can vary depending on the vehicle, but they may include:
* Check Engine Light
* Transmission slipping or jerking
* Difficulty shifting gears
* Loss of power
* Increased fuel consumption
* Engine stalling
Causes
The causes of the P0700 code can also vary depending on the vehicle, but they may include:
* Faulty transmission control module (TCM)
* Faulty transmission solenoids
* Faulty transmission input/output speed sensor
* Faulty throttle position sensor (TPS)
* Faulty engine control module (ECM)
* Low transmission fluid level
* Dirty transmission fluid
Diagnosis
Diagnosing the P0700 code can be complex and time-consuming, and it will typically require a diagnostic tool such as a scan tool or code reader. The technician will use the scan tool to retrieve the code from the PCM and then perform a series of tests to determine the cause of the code.
Repair
The repair for the P0700 code will depend on the cause of the code. In some cases, the repair may be simple, such as adding transmission fluid or replacing a faulty sensor. In other cases, the repair may be more complex, such as replacing the TCM or rebuilding the transmission.
Cost
The cost of repairing the P0700 code can vary depending on the vehicle and the cause of the code. In some cases, the repair may cost as little as $100, while in other cases, it may cost as much as $2,000 or more.
