Will a 700r4 transmission work in 96 Chevrolet w 305?

No, a 700R4 transmission will not directly work in a 1996 Chevrolet with a 305 engine without significant modifications. The 1996 model year saw a shift to the 4L60E electronically controlled automatic transmission. The 700R4 is a mechanically controlled unit. The differences are substantial, including:

* Electronic Control vs. Mechanical Control: The 4L60E uses an electronic control system integrated with the vehicle's computer, while the 700R4 uses a mechanical governor and linkage. This means the 700R4 won't be compatible with the 1996 Chevy's wiring harness and computer.

* Different Torque Converter: The torque converters are different sizes and designs, incompatible between the two transmissions.

* Mounting Points: While there might be some overlap, the mounting points and bellhousing pattern may not be exactly the same, requiring significant fabrication or adapter plates.

* Shift Linkage: The shift linkages and mechanisms are completely different.

In short, while you might *theoretically* be able to make it work with extensive modifications (custom driveshaft, wiring harness changes, custom bellhousing, potentially computer reprogramming, etc.), it would be a very complex and expensive undertaking, far exceeding the cost of finding a correct 4L60E transmission. It's not a practical swap. Sticking with a 4L60E is the vastly simpler and more cost-effective solution.
