Why is my transmission light flashing?

Why is my transmission light flashing?

Transmission light usually flashes due to overheating. If the fluid is low, it is possible for the transmission to overheat. Depending on how much it overheats, the remaining fluid can be pushed out of the vent tube. Low fluid levels and overheating will cause internal transmission damage.

Do you have to reprogram a rebuilt transmission?

To answer your question you should NOT need to reprogram your computer (PCM/ECU) when you replace your transmission as long as it’s a stock replacement (or stock rebuild).

What are the signs of a bad transmission module?

    Can You reflash a transmission without rebuilding the transmission?

    Reflashing new calibrations for the transmission can solve shifting and even wear issues without having to rebuild the transmission. Many OEMs are issuing new calibrations to account for wear to the bands and clutches that they did not see in their initial testing.

    How does reflashing work on a powertrain control module?

    PCMs are built with microchips that can be reprogrammed electronically without being removed from the vehicle. Reflashing is a process where you electronically transfer approved files from a vehicle manufacturer’s website using a diagnostic connector.
