Here's why:
* Different chassis components: Automatic and manual transmissions require different transmission tunnels, drive shafts, clutch components (pedal assembly, hydraulic system, etc.), and potentially even different engine mounts. You're essentially talking about a significant portion of the car's drivetrain.
* Wiring harness: The automatic transmission's wiring harness is different from a manual's. Significant rewiring would be needed.
* Computer control: While the 1994 Accord isn't heavily reliant on computer control compared to later models, some adjustments might be needed to the ECU (Engine Control Unit) to accommodate the manual transmission.
* Parts sourcing: Finding all the necessary parts (transmission, clutch assembly, pedal assembly, driveshaft, etc.) from a donor car in good condition can be challenging and costly.
* Labor: The labor involved is incredibly extensive and requires a skilled mechanic with experience in this specific type of conversion.
In short, while technically feasible, the cost, complexity, and time investment involved in converting a 1994 Honda Accord from automatic to manual usually outweigh the benefits. It's generally more practical and cost-effective to simply buy a 1994 Honda Accord that already has a manual transmission.
