If you’ve ever been stuck in bumper-to-bumper on Te Rapa Straight, crawling through those Matangi backroads, or navigating the roundabouts between Hamilton and Ngaruawahia, you’ll know your car’s transmission cops a fair hiding here in the Waikato. Between the hills out in Pirongia, potholes around Dinsdale, and Hamilton East’s endless stop-start traffic, a gearbox gets plenty of abuse. At Grimmer Motors, we see all sorts – from old Honda Odysseys to late-model Hyundai Ioniqs, Mazda Demios, and the odd Ssangyong Stavic or Peugeot 308. The good news? You don’t need to be a mechanic to keep your transmission out of trouble. Here are five simple tips we give customers every week to keep your transmission going strong, whether you’re doing laps of The Base or commuting to Morrinsville.
1. Keep an Eye on Your Transmission Fluid
Check Your Levels and Colour
Your transmission fluid’s about as important as oil is to your engine. It keeps everything slick, cool, and moving right. One of our techs looked over a Nissan Tiida last week with brown, burnt-smelling fluid – not a good sign. If you can, check your fluid every six months (or get us to do it during a quick car service in Hamilton). You want it looking bright red and smelling sweet. If it’s gone dark or stinks, time for a change. Good, clean fluid stops your gearbox getting hot and bothered. Learn more about the importance of transmission fluid.
2. Always Use the Right Transmission Fluid
Match What Your Car Needs
It’s not just a gimmick – using the wrong fluid can mess things up fast. We’ve seen a couple of Toyota Estima and Renault Koleos owners get caught out with the wrong stuff, and it’s never cheap to put right. Always check your owner’s manual for the exact type, or ask us. If you’re ever scratching your head at Repco on Anglesea St, just give us a bell! The right fluid ensures your gears stay happy and you aren’t dropping cash on avoidable repairs. Why the right transmission fluid matters.
3. Get Regular Transmission Servicing
Stay Ahead of the Game
If you’re clocking up ks on Gordonton Road or ferrying the kids around Rototuna, it pays to get a proper transmission service every 30,000 to 60,000 miles. This can mean flushing out the old fluid, changing the filter, and making sure nothing’s worn out inside (especially on those CVTs in some late-model Mitsubishis). Little fixes stop big, ugly bills later. Book your transmission service.
4. Prevent Overheating
Don’t Let It Cook
The fastest way to send your transmission packing? Letting it overheat. Stuck up Kaimai Hill towing a trailer with a loaded Suzuki APV in the middle of a hot Cambridge summer? That’s where things go wrong. Make sure your cooling system’s cheers – radiators, fans, all that. We’ve even fitted extra coolers for folks pulling horse floats to Te Awamutu shows or caravans out to Raglan. If your temp gauge is acting up or you’re worried, bring it in. Find out about cooling system maintenance.
5. Drive Smart, Not Hard
Gentle’s Best for Gearboxes
Punching it off every green light on Ulster St might feel good, but it wears out your transmission, petrol, everything. Let the car stop before shifting into reverse or park. If you’re shifting between Drive and Reverse on that narrow driveway in Hillcrest, don’t rush it. Hauling the boat to Huntly? Use the right gear so your auto or manual box isn’t straining. These little habits keep your car (and wallet) happy for longer. Tips on driving for transmission health.
