Transmission & Driveline — From the Clutch to the Axle, Edmonton

There's a vibrationat highway speed and three shops have guessed.

Manual and automatic transmissions, clutches, driveshafts, differentials and axles — diagnosed as one system, because a driveline vibration rarely announces where it lives. And when it comes apart, you see both numbers before you choose: rebuild or replace.

Edmonton facility — 20-tonne overhead cranes to pull and set driveline components

Proof of capability

Capability you can check before you commit

20-tonne overhead cranes and the floor space to pull and set heavy driveline components — which is why a transmission or a differential job stays in one shop instead of being split between whoever has the hoist and whoever has the tech, with a tow and a week of waiting between them. Authorized CVIP inspection station and Sennebogen's authorized service provider, working out of a 40,000 sq. ft. Edmonton facility with the diagnostic tooling to confirm a fault rather than guess at it.

What Mach 6 handles

The problems you bring us

Driveline Vibration & Noise Diagnosis

“It's smooth at 80 and shakes at 100.”

Vibration and driveline noise traced across the whole line — u-joints, carrier bearings, shaft balance, angles, and the differential behind them. Speed, load and conditions get reproduced before anything is replaced, and we document what was ruled out. A vibration diagnosed by parts replacement is just an expensive way to guess.

Heavy Truck Transmission Repair & Rebuild

“It's jumping out of gear under load.”

Manual and automatic transmission diagnosis, service, repair and rebuild. What the teardown finds decides the job — and you see the rebuild number and the remanufactured-or-new replacement number side by side, with how much life each one buys, before you approve either.

Clutch Replacement & Actuation Faults

“The pedal's gone long and the driver's fighting it.”

Clutch replacement, plus the hydraulic and air actuation faults that get blamed on the clutch and are not. Adjustment, linkage, air or hydraulic delivery and release bearing all get checked first — because half of what arrives as a worn clutch is an actuation problem that costs a fraction to fix.

Driveshaft, U-Joint & Carrier Bearing Service

“There's a clunk when it takes off.”

Driveshaft, u-joint, carrier bearing and balance work. Driveline angles get measured, not assumed — a shaft that keeps eating u-joints is usually telling you about ride height or a worn mount rather than about the joints.

Differential & Axle Repair

“It's whining and it's getting louder.”

Differential and axle repair, including gear and bearing replacement. A whine that changes with load is a different failure from a whine that changes with speed, and the difference decides whether this is a bearing job or a gearset. You get the finding, the photos and both paths priced.

Driveline Component Removal — Crane Capacity

“The last shop said they couldn't lift it.”

Overhead cranes and the space to pull and set heavy driveline components. It sounds like a facility detail; it is the difference between a job that finishes here and a job that gets sublet, moved, and delayed twice.

The page's best argument

You'll see both numbers before you choose

Once it's apart, there are usually two honest paths: rebuild what's in front of us, or replace it with a remanufactured or new unit. Which one costs less over the life of the truck depends on what the teardown found, how many hours are on the rest of the unit, and how long you plan to keep it — and none of that is knowable from the parking lot. So we show you the findings, the photos, and the rebuild number alongside the remanufactured-or-new replacement number, with what each one buys you. Then you decide. We don't have a house preference, and the estimate you approve is locked either way.

The commitments in writing

Two promises. Both in writing.

The Downtime Promise

Inspection results within 48 hours of your scheduled booking — guaranteed. A comprehensive estimate within 24 hours of diagnostic completion. Worst case, that's 72 hours from drop-off to a number you can act on — and you'll hear from us before then, not after. Every unit leaves with a condition report and a digital vehicle inspection you can make decisions from. No surprises. No delays. Just results.

The Estimate Lock

Serial estimating — approve one number, then watch it grow — is one of the top three issues for fleets in this industry. Our Estimate Accuracy & Approval Policy ends it: once approved, your estimate is locked on price and scope. Changing a locked estimate takes manager approval — and nothing changes without yours.

How the process works

Four steps, same order, every time

Same sequence whether it's one unit or a fleet program — that's what makes the 48-hour and 24-hour commitments something we can actually hold.

  1. Tell us what's down

    Unit, and for a vibration or a noise: the speed, the load and the conditions it shows up under. That detail is worth an hour of bay time.

  2. We diagnose before we quote

    Road test and inspection first, with photos and measurements of what we find. You approve from evidence, not a phone description.

  3. Your number, inside 24 hours

    Parts and labour split out — and where a teardown gives you a choice, both paths priced. Approved means locked; changes take manager approval, and nothing changes without yours.

  4. Back on the road, on the record

    Repaired, road-tested under load, and filed to the unit's digital history — including the teardown findings, which is the document that matters when the truck is sold.

Every job leaves here with a record: what was inspected, what was found, what was approved and what was done. That record is what turns a repair into a maintenance history you can plan against.

FAQs

Questions fleets ask us

Can you diagnose a vibration you can't reproduce in the shop?

Tell us the speed, the load and the conditions it shows up under — that's usually enough to reproduce it on a road test. If it won't show itself, you still get the written record of what was measured and ruled out, so the next attempt starts where this one ended.

Do you rebuild or replace?

Whichever costs you less over the life of the unit — a rebuild, or replacement with a remanufactured or new unit. We'll show you the findings and the numbers for both before you decide.

Don't take the website's word for it

Ask to see the paper. A real teardown report with the photos behind the recommendation, and a locked estimate — before you commit the truck.
