Swapping between the 4L80E and 4L60E transmissions in GM trucks requires careful consideration of the electrical connections, as the transmissions have different connectors and pinouts.
However, the exact wiring modifications can be a bit complex, and while it's possible to re-pin the connector to make it work, it's not just a straightforward pin relocation. There are several factors to consider:
Transmission Connectors: The 4L60E and 4L80E have different connectors, so you'll need to change the actual plug on the wiring harness or get an adapter.
PCM (Powertrain Control Module): The PCM may be programmed differently between the two transmissions. If you're swapping to a 4L60E, the PCM will need to be reprogrammed to work correctly with it.
Wiring Differences: There are differences in the number of pins and the function of each pin between the two transmissions. It's not just a matter of moving wires around. You might need to add or remove certain wires, modify circuits, or even install additional components to make everything work correctly.
Given the complexity, a few potential solutions include:
Harness Adapter or Conversion Harness: Some companies produce adapter harnesses or conversion kits specifically designed for this type of swap. These can make the process more plug-and-play without needing to modify your existing wiring.
Re-pinning: If you're comfortable with electrical work and have access to wiring diagrams for both transmissions, you can re-pin the connector yourself. However, this requires a solid understanding of the wiring and the functions of each transmission.
