Restoring a 1980 G-Wagon: Fixing Transmission, Teaching Manual Driving & More

Engine and Fuel System Revival

• 💡 The 1980 280 GE G-Wagon, sitting for over 10 years, was brought back to life.
• 🚀 The initial start-up used an auxiliary fuel system due to the delicate and compromised original fuel lines.
• 🛠️ The entire fuel system was revamped, including replacing leaking lines, fitting an aluminum pre-filter, and sourcing a factory Bosch fuel pump and post-filter.
• ✨ After injector cleaning and an oil change, the M 110 straight-6 engine ran beautifully with no smoke and minimal lifter tick.

Transmission and Clutch Repair

• ⚠️ The transmission initially wouldn't go into gear, indicating a clutch system issue.
• 💧 The clutch fluid reservoir was found to be low and contained highly contaminated, moisture-laden brake fluid, affecting hydraulic function.
• 🔧 The clutch slave cylinder was identified as leaking, and a new bleeder was installed after a thorough flush and refill with fresh fluid.
• ✅ The clutch system was bled, and the transmission began shifting smoothly into all gears, including reverse.

Drivetrain and Brakes

• ⚙️ The transfer case was serviced, with fluids drained and refilled, revealing its 'S' (rear-wheel drive), 'SA' (all-wheel drive), 'N' (neutral), and 'GA' (all-wheel drive with reduction) modes.
• 🛑 The front brakes were found to be frozen, with stuck pistons and rusty rotors, requiring significant effort to free up and service.
• 🔧 Rear brakes were also found to be non-functional, likely due to rust, but the process of freeing them up was initiated.
• 🚗 The vehicle was confirmed to have functional front brakes and a working drivetrain, though rear brake issues persisted.

Learning to Drive Stick

• 👩‍🏫 The owner attempted to teach his wife how to drive a manual transmission in the G-Wagon.
• 🚦 Initial attempts focused on clutch control, shifting through gears, and understanding the clutch pedal's function.
• 😅 Learning to take off smoothly from a stop, especially on a slight incline, proved challenging but was eventually achieved.
• 🚗 The wife successfully learned the basics of shifting and driving the G-Wagon, though the low power of the vehicle made take-offs more difficult.

Shocks, Windshield, and Final Touches

• 💨 New Bilstein and Sachs shocks were installed on the front and rear, improving ride quality.
• 🪞 A new windshield was fitted by a professional, enhancing visibility and safety.
• 🔧 Various fluids (transfer case, differentials, transmission, coolant) were changed, and greasing of drive shaft components was performed.
• ✨ The G-Wagon was deemed mechanically sound and ready for sale as a rolling project.
