Frequently Asked Questions

The most common signs are slipping gears - where the engine revs but the car doesn't accelerate properly - shuddering or jerking when changing gears, difficulty shifting, unusual whining or clunking noises, a burning smell, warning lights on the dash, or reddish fluid leaking underneath your vehicle. If you notice any of these, get it assessed as soon as possible. Transmission problems rarely improve on their own and the cost of repair generally increases the longer it's left.

Transmission repair costs vary significantly depending on the type of transmission, the make and model of the vehicle, and the extent of the damage. A minor service or fluid change is very different in cost to a full rebuild. We always carry out a proper diagnosis before quoting, and you'll receive a clear, written quote before any work begins. There are no surprises. Call us on 0800 22 8000 and we can give you a better idea once we know what you're dealing with.

It depends on the scope of work. A transmission fluid service can often be completed the same day. A full rebuild typically takes several days, as components need to be stripped, inspected, sourced if required, and reassembled correctly. We'll give you a realistic timeframe when we quote the job and keep you updated throughout.

Yes. We work on automatic transmissions, manual gearboxes, CVT transmissions, DSG transmissions, and differentials across all makes and models. If you're unsure whether we can help with your specific vehicle, give us a call and we'll confirm before you bring it in.

The torque converter sits between the engine and the automatic transmission and transfers power from one to the other. When it fails, the symptoms can be easy to confuse with broader transmission problems - which is why accurate diagnosis matters. Common signs of a faulty torque converter include shuddering at certain speeds, slipping, overheating, and unusual noises. Marshall Transmissions is one of the few workshops in New Zealand that rebuilds torque converters in-house, which means a more accurate diagnosis and a better result.

In most cases we'd recommend against it. Continuing to drive with a transmission fault can turn a manageable repair into a much more expensive one - and in some situations it can be unsafe. If your vehicle is slipping, jerking, making unusual noises, or showing a warning light, call us and we'll advise based on what you're describing. If you're not confident driving it in, let us know and we can talk through your options.

Yes. Our repairs are backed by a warranty on workmanship. The specific terms depend on the nature of the repair, so ask our team for details when you book your vehicle in.
