Frequently Asked Questions

What is the drivetrain and why is it important for home maintenance?

The drivetrain is the group of components that delivers power from the engine/transmission to the wheels. It includes the driveshaft, axles, differential, and sometimes the clutch/flywheel. Maintaining it is critical because failure in any part can lead to a complete loss of vehicle movement or expensive repairs.

Can I use transmission fix additives instead of a full repair?

Additives like Lucas Oil Transmission Fix can often alleviate minor symptoms like slipping or leaks by conditioning seals and improving fluid viscosity. However, they are temporary solutions. If the transmission has severe mechanical damage, a full repair or rebuild will eventually be necessary.

Are universal parts, like hose kits, reliable for replacement?

Universal parts, such as the 6AN transmission cooler hose kit, are reliable when they meet or exceed OEM specifications. Braided stainless steel hoses, for instance, offer excellent resistance to heat and abrasion. Always ensure the fittings and lengths are compatible with your specific transmission model before installation.

What tools are essential for basic drivetrain maintenance?

Beyond standard sockets and wrenches, essential tools include a quality torque wrench (for proper fastener installation), a universal joint for tight spots, fluid pumps/extractors, and vehicle-specific repair manuals (like the ATSG books) for accurate procedures.
