Expert diagnostics. Honest estimates. Same-week repairs. Serving since 1958
Calgary’s Trusted Transmission Repair Specialists
Your transmission is the hardest-working component in your vehicle. When it starts slipping, hesitating, or making noise, every kilometre you delay increases repair costs — and puts your safety at risk.
At Mighty Auto Repairs, we have diagnosed and repaired transmissions and gear systems across every major make and model since 1958. Our Calgary shop combines decades of hands-on experience with modern diagnostic equipment, so we find the real problem fast — and fix it right the first time.

5 Signs Your Transmission Needs Attention Now
Do not wait for a complete failure. Catching transmission problems early saves thousands of dollars. Bring your vehicle in if you notice any of the following:
Slipping gears:
Your engine revs, but the vehicle does not accelerate normally. This is the single most common sign of a failing transmission.
Rough or hard shifting:
You feel jerking, thudding, or clunking when the transmission changes gears — especially under load.
Burning smell or fluid leak:
Red or brown fluid under your car is transmission fluid. A burning smell usually means the transmission is already overheating.
Delayed engagement:
There is a noticeable pause when shifting from Park to Drive or Reverse. A healthy transmission should respond immediately.
Transmission warning light:
Your dashboard warning light is a direct signal from your vehicle’s computer. Never ignore it.
Key Insight: Most transmission failures that require full rebuilds started as a minor fluid or solenoid issue. Early diagnosis at Mighty Auto Repairs can reduce your repair bill by 60–80%.
Our Transmission & Gear Services in Calgary
We handle the full spectrum of transmission and gear repair — from a simple fluid flush to a complete rebuild. Every job comes with an upfront written estimate and no surprise charges.
Transmission Diagnostics
Every repair starts with a thorough diagnosis. We connect your vehicle to our computer scanning equipment, review fault codes, and perform a road test to replicate the issue under real driving conditions. You receive a clear explanation of what is wrong and what it will cost before we touch anything.
Transmission Fluid Service
Transmission fluid degrades over time, losing its lubricating and cooling properties. A transmission fluid service — including a drain, flush, and refill with manufacturer-specified fluid — is one of the most cost-effective ways to extend the life of your transmission. We recommend this service every 60,000–100,000 km, depending on your vehicle and driving conditions.
Transmission Repair
Not every transmission problem requires a rebuild. Many issues — worn solenoids, faulty sensors, damaged seals, and valve body problems — can be repaired efficiently without a full teardown. Our technicians will always recommend the least invasive and most cost-effective solution.
Transmission Rebuild
When internal components are worn beyond repair, a rebuild is the most economical alternative to full replacement. We fully disassemble your transmission, inspect every component, replace all worn parts, reassemble to factory specification, and road test the completed unit before returning your vehicle.
Transmission Replacement
If the destruction is beyond the scope of reconstruction, or when a rebuilt unit is not economical, we source high-quality replacement transmissions — OEM, remanufactured, or quality aftermarket — and install them with a full warranty.
Gear Repair & Gear Services
Gear problems — including differential issues, transfer case failures, and gear grinding — are diagnosed and repaired with the same level of care as transmission work. We service both automatic and manual gear systems across all vehicle types.
Most vehicles are diagnosed the same day. Written estimates before any work begins.

FAQ’s
How much does transmission repair cost in Calgary?
The cost depends entirely on the type of repair needed. A fluid service typically ranges from $150 to $300. A transmission repair for a specific component can range from $400 to $1,500. A full rebuild typically falls between $1,800 and $3,500. A replacement can range from $2,500 to $5,000+. We always provide a written estimate before starting any work, so you know the exact cost upfront.
How long does a transmission repair take?
A diagnostic takes two to four hours. Minor repairs, such as a fluid service or solenoid replacement, are often completed the same day. A transmission rebuild typically takes two to four business days. The full replacement usually takes one to two days, depending on parts availability. We will give you a realistic timeline after the diagnosis.
Should I repair or replace my transmission?
This depends on the extent of the damage, the age and value of your vehicle, and the cost of each option. Our technicians will honestly advise you on the most cost-effective path — and we will never recommend a rebuild or replacement if a simpler repair will solve the problem.
Is it safe to drive with a slipping transmission?
No. A slipping transmission means the vehicle is not transmitting power consistently or predictably. This creates a safety risk, especially when merging or crossing intersections. It also dramatically accelerates damage. If your transmission is slipping, stop driving and call us as soon as possible.
Do you work on both automatic and manual transmissions?
Yes. We service, repair, rebuild, and replace both automatic and manual transmissions across all makes and models, including domestic vehicles, Japanese imports, European vehicles, trucks, and SUVs.
What areas in Calgary do you serve?
Our shop is located in Calgary, and we welcome customers from across the city and surrounding communities. For vehicles that cannot be safely driven, we can advise on towing options.
Do you offer a warranty on transmission repairs?
Yes. Every repair, rebuild, and replacement at Mighty Auto Repairs comes with a workmanship warranty. We stand behind our work. For detailed warranty information, consult our service team during the appointment booking process.
