Here's why:
* Different viscosity and properties: Engine oil and transmission fluid have vastly different chemical compositions and viscosities. Transmission fluid is not designed to withstand the high temperatures and pressures within an engine. It may not provide adequate lubrication, leading to even more damage during any attempt to turn the engine.
* Potential for damage: Transmission fluid can damage seals and other engine components that are not designed to come into contact with it.
* Cleaning issues: Transmission fluid will likely contaminate the engine even further, making repairs significantly more difficult and expensive.
If your car's engine has seized due to a loss of oil, you need professional help. Attempting to fix this yourself with inappropriate fluids will almost certainly result in a more costly repair or even a complete engine replacement. The best course of action is to have the vehicle towed to a qualified mechanic for diagnosis and repair.
