How Much To Change My 93 Honda Accord From Automatic To Manual Transmission


Converting a 1993 Honda Accord from an automatic to a manual transmission typically costs between $1,500 to $3,000 for parts and labor. However, the total cost can vary significantly based on several factors.

Let’s break down the costs and considerations involved in this transmission swap to give you a comprehensive understanding of what to expect.

What Factors Influence the Cost of Converting an Automatic Transmission to Manual?

The total cost to convert your 1993 Honda Accord from automatic to manual transmission is influenced by several key factors:

  1. Parts availability: The age of your vehicle means some parts may be harder to find, potentially increasing costs.
  2. Condition of existing components: If other related parts need replacement, this will add to the total cost.
  3. Labor rates: Shop labor rates vary widely by location and expertise level.
  4. Transmission source: Using a salvaged transmission vs. new or rebuilt will impact the price.
  5. Quality of parts used: OEM parts generally cost more than aftermarket alternatives.
  6. Modifications required: Any custom fabrication or additional modifications will increase costs.
  7. Your DIY skills: Doing some of the work yourself can significantly reduce labor costs.

The combination of these factors means the final cost can vary by $1000 or more between different scenarios. Carefully consider each aspect when budgeting for your conversion project.

What Specific Parts Are Needed for the Conversion?

To convert your 1993 Honda Accord from automatic to manual transmission, you’ll need the following key components:

  1. Manual transmission
  2. Clutch kit (including clutch disc, pressure plate, and throwout bearing)
  3. Flywheel
  4. Clutch master cylinder and slave cylinder
  5. Clutch pedal assembly
  6. Shifter assembly and linkage
  7. Manual transmission mount
  8. Driveshaft (may need modification)
  9. Manual transmission ECU (Engine Control Unit)
  10. Wiring harness for manual transmission
  11. Clutch line
  12. Pilot bearing
  13. Manual transmission fluid

Additional parts that may be required:

  • Shift boot and knob
  • Center console (if different for manual models)
  • Speedometer cable or sensor (if different)
  • Starter motor (manual transmissions often use a different starter)

Keep in mind that some of these parts may be interchangeable with your existing automatic components, potentially reducing the number of new parts needed. However, it’s generally recommended to replace wear items like the clutch kit when doing a conversion.

What Are the Labor Costs Involved in the Conversion?

Labor costs for converting your 1993 Honda Accord from automatic to manual transmission typically range from $500 to $1500. This wide range is due to several factors:

  1. Shop rates: Labor rates can vary from $50 to $150 per hour depending on location and shop expertise.
  2. Job complexity: A straightforward swap might take 8-12 hours, while a more complex job could take 20+ hours.
  3. Unforeseen issues: Rusty bolts, damaged components, or custom fabrication needs can add significant time.
  4. Shop experience: Shops experienced with Honda transmissions may complete the job faster.
  5. Additional services: Some shops may include alignment or other related services in their quote.

To get an accurate estimate, it’s best to get quotes from several local shops that have experience with Honda transmission swaps. Be sure to ask about their warranty on labor and what’s included in their estimate.

Remember, while a lower labor cost might seem attractive, ensure the shop has a good reputation for quality work. A poorly done conversion can lead to expensive problems down the road.

How Much Do the Parts Typically Cost?

The cost of parts for converting your 1993 Honda Accord from automatic to manual transmission can vary widely based on quality and source. Here’s a breakdown of typical costs:

  1. Manual transmission: $300 – $1000 (used/rebuilt/new)
  2. Clutch kit: $150 – $400
  3. Flywheel: $50 – $200
  4. Clutch master and slave cylinders: $100 – $250
  5. Clutch pedal assembly: $50 – $150
  6. Shifter assembly and linkage: $100 – $300
  7. Manual transmission mount: $20 – $80
  8. Driveshaft modifications: $100 – $300
  9. Manual transmission ECU: $100 – $400
  10. Wiring harness: $50 – $200
  11. Clutch line: $20 – $50
  12. Pilot bearing: $10 – $30
  13. Manual transmission fluid: $20 – $40

Total parts cost range: $1070 – $3400

Keep in mind these are approximate ranges. You may find better deals, especially if you’re willing to use used or aftermarket parts. However, critical components like the clutch kit and flywheel are often best bought new for reliability.

Sourcing a complete manual transmission swap kit from a salvage Accord can sometimes be a cost-effective option, potentially costing $500-$1000 for all necessary components. However, you’ll want to ensure the donor car’s parts are in good condition.

Are There Additional Costs to Consider?

When budgeting for your 1993 Honda Accord’s automatic to manual transmission conversion, consider these potential additional costs:

  1. Tools: Special tools may be needed, costing $50-$200 if you’re doing the work yourself.
  2. Alignment: Your car will likely need an alignment after the swap, typically costing $50-$150.
  3. Fluids: Besides transmission fluid, you may need to replace engine oil and coolant, adding $50-$100.
  4. Miscellaneous hardware: Bolts, clips, and other small parts can add up to $50-$150.
  5. Exhaust modifications: Sometimes the manual transmission requires slight exhaust modifications, potentially adding $100-$300.
  6. Upgraded clutch: If you plan to increase engine power, a stronger clutch might be advisable, adding $200-$500.
  7. Transmission programming: Some ECUs may need professional programming, costing $100-$300.
  8. Unexpected repairs: Old parts may break during removal, budget an extra 10-20% for unforeseen issues.
  9. Rental car: If your car is your daily driver, factor in potential rental costs during the conversion.
  10. Increased insurance costs: Manual transmissions sometimes incur slightly higher insurance premiums.

While not all of these will apply to every conversion, it’s wise to account for at least some of these additional expenses in your budget. A good rule of thumb is to add 20-30% to your estimated parts and labor costs for these potential extras.

Is It Cheaper to Buy a Manual Transmission Honda Accord Instead?

In many cases, it may be more cost-effective to sell your automatic 1993 Honda Accord and buy a manual transmission model instead of converting. Here’s why:

  1. Cost comparison: A good condition manual 1993 Accord might cost $1500-$3000, potentially less than the conversion cost.
  2. Time and effort: Buying a manual car saves you the hassle and downtime of a conversion.
  3. Reliability: Factory manual cars often have fewer issues than converted ones.
  4. Resale value: Converted cars may have lower resale value due to concerns about conversion quality.
  5. Warranty: If buying from a dealer, you might get a warranty, unlike with a DIY conversion.

However, there are scenarios where conversion makes sense:

  1. Sentimental value: If your car has personal significance, keeping it might be worth the cost.
  2. Rare models: Some trim levels or color combinations might be hard to find in manual.
  3. Known history: You know your car’s full history and condition.
  4. Custom builds: If you’re planning other major modifications, a conversion can be part of a larger project.

Carefully weigh the costs, time investment, and your personal attachment to your current car when deciding between conversion and replacement.
