* Transfer Case Compatibility: The biggest hurdle is the transfer case. A 1995 Chevy 4x4 likely uses a newer style transfer case (likely an NP241 or similar) that's not directly compatible with the bolt pattern of a TH350's output shaft. You'd need an adapter, which might not even exist readily.
* Output Shaft Differences: The TH350's output shaft and the later 4x4's transfer case input shaft likely have different diameters and/or spline counts.
* Computer Control: 1995 trucks likely have some degree of computer control over the transmission, something a TH350 lacks entirely. This will necessitate bypassing or significantly altering the vehicle's electronic systems.
* Bellhousing: While the bellhousing *might* bolt to the 350 engine, it's not guaranteed, especially depending on which 350 engine you have.
In short, while mechanically *possible* with extensive fabrication and modifications, it's not practical or a recommended swap. A much better option would be to source a transmission that's designed for the 1995 Chevy 4x4 truck, such as a 4L60E (the electronically controlled automatic that was common in that year). Using the correct transmission is significantly cheaper, easier, and safer.
