Will 4l60e transmission out of a 1997 Chevy 4x4 work in 1995 4x4?

It's *possible* but not guaranteed. While both are 4L60E transmissions, there were subtle differences between 1995 and 1997 model years, particularly in the valve body and possibly the electronic controls.

Here's what you need to consider:

* Wiring Harness: The biggest potential issue is the electrical harness. The connectors *might* be compatible, but there's no guarantee. A mismatch could lead to transmission malfunction or even damage.

* Valve Body: Internal differences in the valve body programming between the years could cause shifting problems.

* Torque Converter: Ensure the torque converter is compatible. While likely similar, there could be subtle differences that affect performance.

* Transfer Case: The transfer case interface should be the same, as that's a mechanical connection mostly independent of transmission changes within those years.

In short: It's a risky swap without thorough investigation. You'll need to compare the transmission's part number and electrical connectors very carefully. Ideally, you'd find a 4L60E from a 1995 Chevy 4x4 to ensure compatibility. Attempting this swap without expertise could lead to significant repair costs.
