What is the code for a transmission failure?
These codes all relate to shift solenoid failure. Your TCM tells your transmission how and when to shift by opening one of these solenoids to allow transmission fluid to pass into the transmission’s hydraulic control section for the specific gear.
Where is the Transmission Control Module on a 4L80E?
The 4L80E Transmission system is equipped with a computer called the Transmission Control Module (TCM), located in the left/rear passenger seat compartment which interprets, ana-lyzes and records electronic signals from sensors and switches located on the engine, brake pedal, and transmission.
What does the transmission control module code mean?
You don’t have to worry much about this code – it’s just telling you that there’s an internal error in the transmission control module (TCM). It’s a programming issue. You can take your car to the dealer and have the TCM replaced. This is another purely informational code, telling you that the ECM and the TCM aren’t on speaking terms.
Why do I keep getting the same transmission code?
The output speed sensor may need to be replaced. These codes all report problems with the gear ratio. The only difference in these transmission trouble codes is the gear that’s being identified. They’re all reporting the same error, but they’re reporting it for different gears.
How can I tell if I have a transmission problem?
The first sign that you may be having transmission problems is that the check engine light (CEL) comes on. You can use a generic OBD-II scanner to retrieve CEL faults, but those codes will not be as helpful as the codes stored in the Powertrain Control Module (PCM) module (also known as transmission control unit).
Can a low transmission fluid level cause a problem?
If your Volvo transmission fluid level is even slightly low, it can cause problems such as transmission slipping or engine revving up when you slow down, transmission banging into gear, etc. Here are instructions on how to check Volvo transmission fluid level.
What is the fault code for a Volvo transmission?
Common fault codes are TCM-002A, TCM-002B, P0733, P0734. If your Volvo transmission hesitates to shift gears, it bangs into gear; the problem could be the B4 servo.
