Is the 95 Chevrolet z71 transmission a direct swap with 89 Chevy blazer?

No, a 1995 Chevy Z71 transmission is not a direct swap with a 1989 Chevy Blazer. While both are Chevy trucks/SUVs, there were significant changes in transmissions and drivetrain components between those model years. The bolt patterns, output shafts, and even the overall transmission type might be different. You'd likely run into numerous incompatibility issues, including:

* Transmission type: The 1989 Blazer likely uses a different transmission type (e.g., TH700R4, SM465) compared to the 1995 Z71 (likely a 4L60E).

* Transfer case: The transfer case interfaces would be different.

* Computer control: The 1995 model likely uses electronic transmission controls, while the 1989 might be entirely mechanical or have a simpler electronic system.

* Engine compatibility: Even if you could adapt the transmission, the engine might not be compatible with the newer transmission's bellhousing or computer controls.

In short, a swap would require extensive modifications, custom fabrication, and potentially a complete drivetrain overhaul, making it far more complex and expensive than simply finding the correct transmission for the 1989 Blazer.
