Transmission, Gearbox & Differential Repairs in Pontefract

Gearbox trouble is worth catching early, because the difference between an oil change and a rebuild is often just how long it has been left. Bring it to RDA Car Sales in Upton, Pontefract for an honest diagnosis.

Gearbox and Differential Work in Pontefract

The transmission takes everything the engine produces and delivers it to the wheels, which makes it one of the hardest-worked assemblies on the car and one of the most neglected. Many manufacturers describe the oil in a manual gearbox as filled for life, which holds up rather better in a brochure than it does at 120,000 miles on West Yorkshire roads.

Symptoms vary by type. A manual box tends to announce itself through a crunch into second, a whine that changes with speed, or a gear that jumps out under load. An automatic more often slips, hunts between gears, or thumps into a shift. A differential usually whines or hums and gets worse on a trailing throttle. We diagnose which assembly is actually at fault before recommending anything, because these are expensive parts to replace on a guess.

Frequently Asked Questions

Does gearbox oil really need changing?

Plenty of manufacturers call it filled for life, but that assumes a life shorter than most cars around here actually get. Gear oil shears and degrades, and on a high-mileage manual box a fresh fill of the correct specification often improves a notchy or crunchy change noticeably. On automatics it matters even more, because the oil is doing hydraulic work as well as lubricating.

Why does my car crunch going into second gear?

Usually a worn synchromesh on that gear, and second is typically first to go because of how often it is used from cold. It can also be a clutch not fully releasing, or simply the wrong or badly degraded oil in the box. Those are very different repairs, so it is worth diagnosing properly rather than assuming the worst.

What does a whining differential mean?

A whine or hum that changes with road speed, and often changes character between accelerating and coasting, usually points at wear in the crown wheel and pinion or a failing bearing. Caught early it can sometimes be addressed with an oil change and a bearing; left long enough it becomes a rebuild or an exchange unit.

Can you repair an automatic gearbox?

It depends on the fault. Solenoid faults, sensor faults, oil and filter problems and linkage issues are all repairable on the car. Internal mechanical damage to the clutch packs or torque converter generally means an exchange unit, and we'll be straight with you about which side of that line your car falls on.

Is it worth repairing a gearbox on an older car?

Sometimes it plainly isn't, and we'd rather say so. We'll give you the honest cost of the repair against what the car is worth, and if the sensible answer is to change the car rather than the gearbox, we'll tell you — we sell cars as well as fix them, and we'd rather keep you as a customer than sell you a repair you regret.
