Automotive Division
Professional diagnosis, repair, and full restoration of manual and automatic transmission systems for private, commercial, and fleet vehicles — backed by experienced technicians and structured engineering processes.
What We Do
The transmission and drivetrain are the critical link between your engine and your wheels. Every gear change, every acceleration, every hill climb depends entirely on these systems working in precise mechanical harmony. When they fail — even partially — performance, efficiency, and safety are all compromised.
At AutoBore Pro, our technical team handles the full spectrum of transmission and drivetrain faults — from minor fluid-related degradation to complete gearbox overhauls — on both manual and automatic vehicles, commercial trucks, and large fleet operations.
"A transmission fault left unaddressed rarely stays minor. Early intervention is always significantly cheaper than a complete drivetrain replacement."
Know the Warning Signs
Do not ignore these indicators. Early diagnosis prevents minor faults from becoming catastrophic failures.
Resistance, grinding, or a refusal to engage a gear cleanly — in both manual and automatic vehicles — is a clear sign of internal transmission wear or synchroniser damage.
Your vehicle unexpectedly changes gear without driver input, or the engine revs rise without a proportional increase in road speed. This is a dangerous fault requiring immediate attention.
Mechanical grinding during gear changes or a persistent whining sound at speed typically indicates worn bearings, damaged gear teeth, or low transmission fluid under pressure.
A noticeable lag between pressing the accelerator and the vehicle actually moving forward — often accompanied by engine revving without forward momentum — points to clutch slip or automatic transmission hydraulic failure.
Red or dark-brown fluid pooling under your vehicle is transmission fluid. Low fluid levels lead to overheating, accelerated wear, and ultimately complete transmission failure if not addressed.
Unusual vibrations felt through the floor or gear lever — especially at speed or during gear changes — are often caused by worn universal joints, an unbalanced drive shaft, or damaged differential components.
Root Causes
Most transmission failures are preventable. Understanding the root cause is the first step to protecting your vehicle and avoiding costly repairs.
Most failures traceable to
Neglect Over 70% of premature transmission failures result from deferred maintenance or continued operation after early warning signs appear.Transmission fluid is both a lubricant and a hydraulic medium. When levels drop or the fluid degrades, internal components run dry — causing metal-on-metal friction, overheating, and rapid wear of clutch packs, gears, and bearings. This is the single most common cause of premature failure.
⚠ Most Common CauseConsistently operating beyond the vehicle's rated payload capacity places enormous strain on gearbox internals, the drive shaft, and differential components. This is particularly common in commercial haulage operations where vehicles are routinely overloaded — causing accelerated bearing failure and gear damage.
Commercial VehiclesFailure to service the transmission at manufacturer-recommended intervals allows degraded fluid to remain in the system, wear particles to accumulate, and minor seal leaks to become major ones. Deferred maintenance is rarely cheaper in the long run — it converts a ₦15,000 fluid service into a ₦400,000+ overhaul.
PreventableRepeated hard gear changes, sudden acceleration from standstill, and rapid deceleration generate extreme mechanical shock loads within the gearbox. Over time this degrades synchroniser rings, wears clutch packs prematurely, and fatigues gear teeth — often in vehicles that have otherwise been routinely serviced.
Driver BehaviourIn manual transmission vehicles, improper clutch technique — riding the clutch pedal, partial engagement at speed, or holding the vehicle on a hill using the clutch — generates continuous heat and friction on the clutch plate and pressure plate. This leads to early glazing, slipping, and ultimately complete clutch failure well before the expected service life.
Manual VehiclesUniversal joints (UJs) allow the driveshaft to transmit torque through constantly changing angles. When they wear or seize — usually due to grease loss or corrosion — the resulting vibration and imbalance places severe side-loading on gearbox output bearings and differential input flanges, accelerating wear throughout the entire drivetrain.
DrivetrainDo Not Delay
A small warning sign today becomes a catastrophic failure tomorrow. Ignoring transmission problems always results in a significantly higher repair cost — and often, a complete replacement.
Total mechanical breakdown — the vehicle becomes immovable, requiring a full transmission replacement or rebuild.
Worn gears and damaged bearings require individual component replacement — costs that escalate rapidly once internal contamination spreads.
Sudden gear loss or driveshaft failure mid-journey creates a dangerous breakdown — especially at speed or in heavy traffic.
A slipping or inefficient transmission forces the engine to work harder, consuming significantly more fuel per kilometre.
Loss of drive or unexpected gear slip at highway speeds, on slopes, or in traffic directly endangers the driver, passengers, and other road users.
What We Offer
From single-component replacement to complete gearbox overhaul — our technical team provides structured, accountable repair services with clear diagnosis and transparent pricing.
A thorough mechanical and road-test assessment to accurately identify the root cause of your transmission problem before any repair work begins.
Complete clutch system replacement using quality-matched components — restoring smooth, precise gear engagement and eliminating clutch slip.
Targeted gearbox repairs — from individual bearing and seal replacements through to full disassembly, component inspection, and precision reassembly.
Repair and restoration of the complete drivetrain — from universal joints and drive shaft balancing through to full differential servicing and rebuild.
A full factory-standard rebuild for severely worn or damaged transmissions — disassembly, full component inspection, replacement of all wear items, and precision reassembly to specification.
Scheduled fluid drain, flush, and refill with manufacturer-specified transmission fluid — the single most important preventive measure for extending transmission life.
Structured Engineering
Every transmission job follows a strict, documented five-step process — giving you full visibility from diagnosis through to final handover.
We conduct a thorough visual inspection and a controlled road test to replicate and identify the fault symptoms first-hand.
Full mechanical teardown and component analysis identifies the exact cause of failure — no guesswork, no unnecessary parts replaced.
You receive a detailed, honest quotation specifying exactly what needs to be done, what parts will be used, and the expected completion time.
All work is carried out by experienced technicians using quality-matched components and correct tooling — to manufacturer specification.
The vehicle undergoes a post-repair road test and final inspection to confirm the fault is fully resolved before we hand back the keys.
Our Coverage
We service manual and automatic transmission systems across a wide range of vehicle types — from private cars to heavy commercial trucks and full fleet operations.
For transport companies and logistics operators running multiple vehicles, we offer structured fleet maintenance agreements covering transmission servicing, inspections, and priority repair slots.
