Tag T18 transmission

Swapping from a C6 automatic to a T18 manual transmission is a solid choice for durability and control. Here’s a rundown of what you’ll need and consider:

Parts Required

1. T18 Transmission:

   • Make sure it’s in good condition. Check for any worn gears or syncros.

2. Clutch Assembly:

   • You’ll need the clutch disc, pressure plate, and release bearing compatible with the T18.

3. Flywheel:

   • The flywheel from a manual transmission setup. It must match your engine’s balance (either internally or externally balanced).

4. Bellhousing:

   • A bellhousing that fits both your engine and the T18.

5. Clutch Pedal Assembly:

   • This includes the clutch pedal and any associated linkage or hydraulic components, depending on your setup.

6. Clutch Linkage or Hydraulic System:

   • If your truck uses a mechanical linkage, make sure everything is intact. For hydraulic systems, ensure the master and slave cylinders are in good shape.

7. Driveshaft:

   • You might need to modify the length, as the T18 can be a different length than the C6.

8. Crossmember and Mount:

   • Check if the crossmember needs adjustment or if a new mount is necessary.

9. Shifter and Boot:

   • A T18 shifter with a boot to seal the cab.

10. Floor Pan Cover:

    • You might need to modify the floor pan or get a cover for the new shifter location.

Additional Considerations

• Starter: Ensure the starter is compatible with the manual flywheel.
• Transmission Cooler: You can remove the C6’s cooler if you’re not using it elsewhere.
• Wiring: It might be necessary to change or bypass the neutral safety switch wiring.
• Gear Ratios: Be prepared for the different gear ratios. The T18 has a very low first gear, which is great for torque but may take some getting used to.

Pro Tips

• Match the Transmission to the Engine: Make sure your flywheel and clutch are the correct size for the engine you’re working with.
• Documentation: Keep track of all parts and take photos during disassembly for easier reassembly.
• Community: Check out resources like the Bullnose Ford subreddit or the Bullnose Garage channel for more insights and community help.

Swapping transmissions can be a rewarding project that improves your truck’s capability and driving experience. Good luck, and feel free to reach out with more questions!

Converting your 1984 F250 from 2WD to 4WD is quite the project! It’s a doable endeavor if you’ve got the time, tools, and determination. Let’s break down the process and the main components you’ll need to tackle.

Key Components Needed

1. Front Axle:

   • You’ll need a solid Dana 44 or Dana 60 front axle, depending on the weight and intended use of your truck. The Dana 60 is heavier duty and might be preferable, especially for an F250.
   • Ensure you get the necessary radius arms, coil springs, and brackets.

2. Transfer Case:

   • The NP205 is a solid choice for durability. You’ll need the appropriate transfer case adapter to mate with your existing T18 transmission.
   • Double-check your driveshaft lengths, as they will likely need to be custom made or sourced.

3. Driveshafts:

   • Front and rear driveshafts will need adjusting or replacing to fit the new setup. Be prepared to have custom ones made or modified.

4. Suspension and Steering:

   • 4WD conversion may require modifications to the suspension, such as installing leaf springs or converting to coil springs, depending on your front axle choice.
   • Steering components will need upgrading to handle the 4WD setup, like a steering box compatible with 4WD and potential linkages.

5. Crossmember and Mounts:

   • Ensure you have the right crossmember and mounts for the transfer case. Fabrication might be necessary.

Steps for Conversion

1. Planning and Research:

   • Gather parts and research thoroughly. Look for a donor truck if possible, as it can provide many of the necessary components in one go.

2. Front Axle Installation:

   • Remove the existing 2WD front suspension and install the 4WD front axle. This might involve welding new brackets and modifying the frame slightly.

3. Transfer Case and Transmission:

   • Remove the existing transmission if needed to install the transfer case adapter. Install the transfer case and ensure proper alignment and support.

4. Driveshafts and Linkages:

   • Install or modify driveshafts to fit the new setup. Ensure the angles are correct to avoid vibrations.

5. Steering and Brakes:

   • Update the steering linkages and ensure brakes are configured for the new axle setup. Consider upgrading to heavy-duty brakes if not already done.

6. Testing and Adjusting:

   • Test drive and check for any unusual noises or behaviors. Adjust as necessary.

Pro Tips

• Donor Truck: Finding a similar generation 4WD truck as a donor can save you time and hassle, especially for components like axles, transfer case, and linkages.

• Documentation: Keep track of what changes you make and any custom work done for future reference or troubleshooting.

• Community Resources: The Bullnose Ford subreddit is a great place to connect with others who may have tackled similar projects.

Converting to 4WD is a substantial project but can be highly rewarding, enhancing the capability and value of your truck. Good luck, and enjoy the process! If you need more detailed guidance along the way, feel free to ask.
