CheckoutThe electronic transmission control unit General Motors 6L80E 6L90E must be replaced if critical electrical errors (example P0700 and P2714) are detected as a result of computer diagnostics. Another common problem is the physical aging of the board. The loss of the physical qualities of the board components is a consequence of exposure to high temperatures that occur as a result of overheating of the friction components of the transmission and, consequently, the transmission fluid, which in turn performs not only a lubricating and hydraulic function, but also the function of cooling all transmission components, including the electronic control unit (ECU).
As a result of overheating of the transmission fluid, the processor of the block, which cannot be replaced, often burns out, only the replacement of the block assembly.
After replacement with a new or working control unit, it is necessary to install software, "firmware", which is provided by the vehicle manufacturer and takes into account the individual configuration of the engine and transmission.
For successful installation of the "firmware" software, you must select the unit in accordance with the year of manufacture of the car and the compatible original catalog number of the electronic unit.
ECU part numbers that are in the same column are interchangeable between for programming.
