The sheer number of parts available for this model – everything from replacement parts to aftermarket upgrades – was a major factor in my decision. I needed a car with a robust chassis that could handle the stresses of the conversion, and the Mustang’s reputation for durability was a huge plus. Plus, let’s be honest, the sentimental value of owning a classic muscle car played a part too. I spent weeks researching different years and models, comparing parts availability, and weighing the pros and cons of each. Considering the cost of parts and the potential challenges, I felt the ’85 Mustang was the sweet spot – a balance between affordability, parts accessibility, and mechanical simplicity. It was a gamble, of course, but a calculated one based on extensive research and the wisdom of countless online forums. Ultimately, I felt confident that I’d made the right choice, and the journey ahead, while daunting, felt achievable.
Gathering the Parts and Tools
Gathering the necessary parts and tools was a surprisingly lengthy process. My initial parts list, compiled from various online resources and forums, seemed manageable at first, but it quickly expanded as I delved deeper into the project. I started with the core components⁚ a used T5 manual transmission sourced from a reputable salvage yard (after much deliberation and comparison shopping!), a clutch assembly, a new flywheel, a clutch pedal assembly, and a shifter mechanism. Finding a suitable donor car for some of these parts proved more challenging than expected; many were either overpriced or in poor condition. Beyond these major components, I needed a myriad of smaller parts⁚ various bolts, nuts, washers, seals, and gaskets. I meticulously documented every single part, cross-referencing part numbers and comparing prices from different suppliers. The cost of these seemingly insignificant items added up surprisingly quickly. Then there were the specialized tools. I already owned a basic set of hand tools, but I needed a few specialized pieces⁚ a transmission jack, a torque wrench (essential for ensuring proper tightening of bolts), various socket sets, and a clutch alignment tool. I also invested in a shop manual specific to my Mustang’s year and model, a worthwhile investment that proved invaluable throughout the process. This manual provided detailed diagrams and instructions, saving me countless hours of frustration and potential mistakes. Beyond the tools, I also stocked up on consumables⁚ plenty of rags, various types of grease, penetrating oil, and brake cleaner. Organizing all these parts and tools in my garage was a project in itself, but it made the actual conversion process much smoother. I spent weeks meticulously gathering everything, ensuring that I had everything I needed before I even touched the car.
The Conversion Process
The conversion itself was a marathon, not a sprint. I started by carefully documenting the existing automatic transmission’s location and connections, taking numerous photos and making detailed notes. Then came the painstaking process of removing the automatic transmission. This involved disconnecting various linkages, electrical connectors, and hydraulic lines. I worked methodically, carefully labeling everything to avoid confusion during reassembly. My trusty shop manual was a lifesaver here, guiding me through each step. Once the automatic transmission was out, I prepared the engine for the manual transmission. This included installing the new flywheel and clutch assembly. Aligning the clutch was a delicate operation, requiring patience and precision. I used the clutch alignment tool to ensure everything was perfectly centered before tightening the bolts. Next, I carefully installed the manual transmission, using the transmission jack to maneuver it into place. This was arguably the most physically demanding part of the project, requiring considerable effort and precision. Connecting the clutch cable, shifter linkage, and driveshaft was a fiddly job, but again, my detailed notes and the shop manual were invaluable. I double-checked every connection, ensuring everything was secure and properly aligned. After that, I tackled the wiring harness modifications. This involved splicing and re-routing several wires to accommodate the manual transmission’s different requirements. I carefully followed the wiring diagrams in my shop manual, making sure to use the correct connectors and solder joints. Throughout the entire process, I took frequent breaks to avoid fatigue and maintain focus. It was a multi-day endeavor, punctuated by moments of frustration and triumph. The sheer number of bolts, nuts, and connections was overwhelming at times, but the satisfaction of seeing the project progress kept me going. Each successfully completed step reinforced my determination to see it through to the end. Finally, after several days of intense work, I had a fully installed manual transmission.
Testing and Fine-Tuning
With the manual transmission installed, the moment of truth arrived. I cautiously turned the key, and the engine roared to life. The initial test drive was nerve-wracking; The clutch engagement felt a bit rough, and the shifting wasn’t as smooth as I’d hoped. I experienced some minor grinding during gear changes, indicating the need for adjustment. I spent the next few hours meticulously fine-tuning the clutch cable adjustment. This involved making small incremental adjustments and testing the engagement point until I found the sweet spot. Getting the clutch adjustment just right was crucial for smooth shifting and preventing premature wear. I also made adjustments to the shifter linkage. The throws felt a bit long initially, so I shortened them to improve the shifting feel. After several adjustments and test drives, the shifting became noticeably smoother. The grinding disappeared completely, and the clutch engaged smoothly. However, I noticed a slight vibration at higher RPMs. This pointed towards a potential imbalance in the driveshaft. I decided to take the car to a local mechanic specializing in drivetrain components. He expertly balanced the driveshaft, eliminating the vibration entirely. The improvement was dramatic. The car now felt significantly more responsive and engaging. The precise control offered by the manual transmission was a revelation. I spent several more hours driving the car under various conditions, testing acceleration, braking, and handling. I meticulously checked for leaks, ensuring everything was functioning as it should. I also paid close attention to the engine temperature and oil pressure, monitoring for any anomalies. Once I was completely satisfied with the car’s performance and the absence of any issues, I considered the conversion a complete success. The transformation was incredible. The car’s character had been completely altered, offering a level of driver engagement that was previously unimaginable. It was a rewarding experience, proving that with patience, persistence, and a good set of tools, even the most challenging automotive projects can be accomplished.
