Engine Replacement
In Simple Terms:
Sometimes, despite the best care, an engine can reach the end of its lifespan due to age, wear and tear, or significant damage. An engine replacement is essentially replacing the entire old engine with a new or remanufactured one.
How do you know you need it?
Think of your truck’s engine as its heart. Over time, just like any hard-working heart, it can wear out, get seriously damaged, or just not be powerful enough for what you need anymore.
You’ve been noticing a steady decline in your truck’s performance for a while now. It’s not just a slight loss of power anymore; it’s struggling on even mild inclines, and the acceleration is painfully slow. There’s a persistent knocking sound coming from under the hood that’s getting louder and more concerning.
You’ve taken it in for repairs multiple times, addressing various issues, but the problems keep coming back, and the mechanic has mentioned that the internal damage is significant and likely to worsen. Oil consumption has skyrocketed, and you’re constantly having to top it off. The repair bills are piling up, and you’re starting to lose confidence in the truck’s reliability for those important hauls.
At this point, you’re likely facing a tough decision: keep pouring money into a failing engine or consider a complete engine replacement to restore your truck’s power, reliability, and peace of mind for the long haul.
What you can expect from us:
An engine replacement is a significant undertaking that requires precision and expertise. Our Red Seal certified mechanics, with their extensive experience, carefully remove the old engine, inspect all related components, and then install the new or remanufactured engine. This involves disconnecting and reconnecting numerous mechanical and electrical systems, ensuring everything is properly aligned and torqued to factory specifications.
As Powerstroke, Cummins, and Duramax specialists (and experts on all other makes), we have the in-depth knowledge to handle the specific requirements of different engine types, ensuring a seamless and reliable engine replacement that will get your truck back on the road with renewed power and performance.

Transmission Replacement
In Simple Terms:
The transmission is what allows your engine’s power to be transferred to the wheels, enabling you to shift gears and control your speed. Like an engine, a transmission can sometimes fail due to wear, damage, or internal issues. A transmission replacement involves replacing the entire old transmission with a new or remanufactured one.
How do you know you need it?
Your truck is acting up. You’re out on the road, and suddenly your truck starts acting erratically. You notice the gears slipping, causing the RPMs to surge without a corresponding increase in speed. Shifting feels rough and jerky, almost violent at times, and you might even hear unusual clunking or grinding noises coming from underneath.
It’s becoming increasingly difficult to get the truck into certain gears, or it might even pop out of gear unexpectedly. You’ve tried adjusting your driving, but the problem persists and seems to be getting worse with each mile. You’re starting to worry about getting stranded, and the thought of towing your heavy-duty rig is unsettling.
These are clear indicators that your transmission is failing and likely needs a complete replacement to ensure smooth, reliable power delivery and prevent further damage.
What you can expect from us:
A transmission replacement is a complex procedure that our skilled Red Seal technicians handle with care and precision. We carefully disconnect the old transmission, remove it from the vehicle, and then install the new or remanufactured unit.
This involves ensuring proper alignment, fluid levels, and connection to the engine and drivetrain. With over 20 years of experience working on a wide variety of diesel trucks, including Powerstroke, Cummins, and Duramax models (as well as all other makes), we have the expertise to ensure a smooth and reliable transmission replacement, restoring your truck’s ability to shift smoothly and efficiently.

Rebuilds
In Simple Terms:
Instead of completely replacing a major component like your engine, transmission, or differential, a rebuild is like giving it a new lease on life. We carefully take it apart, clean and inspect all the internal parts, replace any worn or damaged components with new ones, and then put it all back together.
How do you know you need it?
Is your diesel seems to be going downhill. You’ve noticed a gradual decline in your truck’s performance over time. It’s not a sudden catastrophic failure, but more of a persistent nagging. Your engine might be producing less power than it used to, feeling sluggish even when unloaded, and you’ve started noticing a bit more smoke than usual.
Perhaps there’s a slight but consistent knocking or ticking sound that wasn’t there before. Similarly, your transmission might not be shifting as smoothly as it once did. You feel a hesitation between gears, or maybe a slight shudder. You might even hear a whine or a hum that seems to be getting louder. When it comes to your drivetrain, you might have noticed a clunking sound when accelerating or decelerating, or perhaps a persistent vibration at certain speeds.
You know your components aren’t completely shot, but they’re definitely not operating at their peak. Instead of a full replacement, which can be a significant investment, a thorough rebuild by experienced technicians could be the ideal solution to restore performance and extend the life of your engine, transmission, or differential without breaking the bank.
What you can expect from us:
Our Red Seal certified technicians are highly skilled in performing meticulous rebuilds of diesel engines, transmissions, and differentials. With over 20 years of experience, we have the expertise to identify which components can be salvaged and which need replacing.
For an engine rebuild, this involves tasks like cylinder honing, crankshaft polishing, valve grinding, and installing new pistons, rings, bearings, and seals. For transmissions, we inspect and replace clutches, bands, gears, and seals. For differentials, we examine and replace bearings, gears, and seals, ensuring proper backlash and preload.
As specialists in Powerstroke, Cummins, and Duramax engines (and all other makes and models), we understand the specific tolerances and requirements of each, ensuring a high-quality rebuild that meets or exceeds original specifications, providing reliable performance for years to come.

Differentials
In Simple Terms:
The differential is a key component in your truck’s drivetrain that allows the wheels on the same axle to spin at different speeds when turning. This is essential for smooth cornering and prevents damage to the axles and tires.
How do you know you need it?
Tough turns and strange vibrations? You’re maneuvering your truck, especially during tight turns at low speeds, and you notice a strange clunking, clicking, or popping sound coming from underneath. It might even feel like the wheels are momentarily binding or skipping.
You might also hear a persistent humming or whining noise that changes with your speed, or perhaps a vibration that you can feel through the floorboards. You’ve checked your tires, and they seem fine, but this unsettling noise and feeling persist. You might also notice gear oil leaks under your truck near the axles. These are strong indicators that something isn’t right with your differentials, the components responsible for allowing your wheels to turn at different speeds.
Ignoring these symptoms can lead to more serious and expensive damage, so getting your differentials inspected and serviced by experts is crucial for maintaining smooth and safe operation of your diesel truck.
What you can expect from us:
Our Red Seal certified technicians are experts in diagnosing and servicing differentials. Whether it’s a simple fluid change, a bearing replacement, or a complete differential rebuild or replacement, we have the knowledge and tools to get the job done right.
We start with a thorough inspection to determine the exact issue. For repairs, we use quality parts and precise techniques to ensure proper gear meshing and smooth operation. For a swap, we carefully remove the old differential and install a new or remanufactured unit, ensuring proper alignment and lubrication.
With our experience on all makes and models, including the specific needs of Powerstroke, Cummins, and Duramax trucks, you can trust us to keep your truck turning smoothly and efficiently.

Timing Belts
In Simple Terms:
The timing belt (or sometimes a timing chain) is a critical component that synchronizes the rotation of the engine’s crankshaft and camshaft. If it fails, it can cause serious and expensive engine damage. While not all diesel engines use timing belts (some use chains), for those that do, regular inspection and replacement are vital.
How do you know you need it?
You’re hearing a ticking or slapping noise from the engine area. You know that regular maintenance is key to keeping your diesel running reliably, and you’re aware that certain components have scheduled replacement intervals. You might not experience a sudden, dramatic failure with a timing belt, but you’ve noticed your truck is approaching or has exceeded the manufacturer’s recommended mileage or time for a timing belt replacement.
You might have even found a reminder sticker from a previous service. While your truck might seem to be running fine now, you understand that a broken timing belt in many diesel engines can lead to catastrophic internal engine damage – bent valves, damaged pistons, the works. That’s a repair bill no one wants.
So, even without obvious symptoms, the awareness of the mileage or time milestone approaching, coupled with the understanding of the potential for severe consequences if it fails, is the trigger that tells you it’s time for preventative timing belt service to protect your investment and avoid a major breakdown.
What you can expect from us:
Our Red Seal certified technicians can inspect your diesel truck (if applicable) to determine if it uses a timing belt and assess its condition. If replacement is due or recommended, we follow precise procedures to remove the old belt and install a new one, along with any associated components like tensioners and idler pulleys.
Because timing belt replacement is a critical procedure that must be done correctly to avoid engine damage, our over 20 years of experience, including working on various diesel engines that utilize timing belts, ensures the job is done accurately and to manufacturer specifications. We can also advise you on the recommended replacement intervals for your specific vehicle.
Note: It’s important to know that many modern diesel engines use timing chains, which generally have a much longer lifespan than timing belts.
