We’re always particular about the products we choose to stock. If we’re going to recommend something to our customers, we want to know there’s some serious thinking behind it.

That’s why we’re now stocking Hot Shot’s Secret.

Developed for both diesel and petrol engines, Hot Shot’s Secret produces highly concentrated additives, oils and fluids designed to target specific engine problems, improve performance and help equipment go the distance.

What got our attention? Their “Powered by Science” approach.

Products are developed and tested through their own R&D laboratory, independent dynamometer testing and real-world applications before they hit the market.

No one-size-fits-all bottle promising to magically fix everything. Products developed for specific jobs and specific problems.

Hot Shot’s Secret is now available in-store. Talk to us about your vehicle and what you’re trying to achieve, and we can point you in the right direction.

Dan summed it up better than we could. Not a franchised dealership experience… but a workshop that actually knows these trucks, inside and out.

That's the whole point of specialising. When you bring your Ram, Ford, Chev or GMC to us, you're not getting a generalist having a guess. You're getting a team that's spent years on these exact platforms, and it shows in the result.

Thanks for the kind words Dan, we truly appreciate everyone who takes the time to leave us a review.

Nobody thinks about their air con until the first really hot day of the year, and by then, everyone's likely booked out.

Spring is actually the smart time to get it checked, before the workshop calendar fills up with summer breakdowns.

What we test:
✔ Refrigerant level and system pressure
✔ Compressor operation under load
✔ Cabin air filter — a blocked filter kills airflow before the system even gets a chance
✔ Condenser condition — road debris and insects can build up over winter and restrict airflow

An air con system that's low on refrigerant doesn't fail all at once. It just gets a little weaker every year until the day you actually need it and it's not there.

Get it looked at now, while there's no urgency. ✆ (07) 4636 6883

Every mechanic on our floor has been trained specifically on American diesel platforms, not handed a generic scan tool and told to have a go.

That's a deliberate choice, and it costs us in time and training investment every single year. New model years land, calibrations change, and aftertreatment systems get more sophisticated. If we're not keeping pace, we're not doing our job properly.

It's part of why trucks keep finding their way to us from Brisbane, Rocky, and everywhere in between. Not because we're the closest workshop, but because the depth of knowledge here is hard to find anywhere else in the state.

We hear a version of this a lot, and more often than not, it's a boost leak.

Your turbo builds boost pressure and pushes it through the intercooler piping to the engine. If a boot's split, a clamp's loose, or a hose has perished, some of that pressure escapes before it ever reaches the cylinders.

What that looks like from the driver's seat:
→ Power that drops off under load or towing
→ A hissing sound from the engine bay under acceleration
→ Black smoke as the engine tries to compensate with more fuel
→ Boost gauge readings lower than they should be

A boost leak won't always throw a code straight away, which is why it gets missed. We pressure test the whole intake system to find leaks generic diagnostics can't catch.

If your truck's lost some of its punch, let’s take a look.

Big news for Cummins fans. Ram's updated 2500 and 3500 lineup is landing with the most significant overhaul to the 6.7L Cummins in years… more power, more torque, and a new 8-speed ZF automatic behind it.

Every time a platform gets a major update, the diagnostic and service requirements shift with it. New engine calibration, new transmission logic, different fault code behaviour. We make it our business to stay ahead of these changes before the trucks start rolling into workshops, not after.

If you're running the outgoing HD Cummins or you're eyeing off the new one, we're already across what's changed and what it means for servicing.

Spring's here, and across Queensland that means one thing for truck owners: the caravans and boats are coming out of storage, and the adventures are being planned!

Before you load up and head off, it's worth getting ahead of the things winter quietly wore down.

What we recommend checking before your next trip:
✔ Tyres — tread, pressure, and condition after months of cold-morning driving
✔ Brakes — pad wear and fluid condition, especially if you've been towing
✔ Cooling system — coolant condition and hose integrity before it's under real load again
✔ Suspension and steering — winter potholes take a toll, and towing exposes it fast

A pre-trip check takes an hour. A breakdown on the highway with a van on the back will take a lot more than that!

A generic OBD scanner will read a fault code on any car. It won't tell you what's actually happening inside a modern Ram, Duramax or Powerstroke aftertreatment system.

That's the gap most workshops run into with American diesels… the software stops short of the depth these platforms actually need.

We've invested in manufacturer-level diagnostic software for Ford, Chevrolet, GMC and Ram specifically, because a fault code is only the starting point. Live data like actual sensor readings, actuator tests, system behaviour under load, is where the real diagnosis happens.

It's the difference between replacing parts on a guess and knowing exactly what's failed before you spend a cent.

If you've had a fault "fixed" more than once without it actually going away, that's usually why.

There's nothing better than hearing that a customer drives away feeling confident. Not just in their vehicle, but in the service they've received.

For us, it's never just about just completing a service. It's about taking the time to explain what we've done, answer your questions, and make sure you understand exactly what's happening with your vehicle.

Thank you for trusting us with your RAM 2500 and for taking the time to leave such a thoughtful review, Casey. We truly appreciate your support and look forward to seeing you again for your next service!

At MS Mechanical we don't believe in guessing, we believe in testing.

In this video, Michael takes you through the diagnostic process for a 4R100 transmission solenoid pack, carefully bench testing each circuit, recording the results and comparing every reading against manufacturer specifications.

By following a systematic process, we can determine whether the fault lies with the solenoid pack itself, deeper within the transmission, or if further diagnosis is required.

It's all part of delivering accurate repairs, avoiding unnecessary part replacements, and giving our customers confidence in the work we do.
