Transmission Rebuild & Replacement Service

Transmission problems can start small—delayed shifting, slipping, shuddering, or a warning light—and quickly turn into expensive repairs if ignored. At Heritage AutoPro, we provide accurate transmission diagnostics, transmission repair, and rebuild/replacement options in Calgary SE & SW for cars, trucks, SUVs, and vans.

We focus on confirming the cause first, then giving you clear options—so you don’t waste money chasing symptoms.

 

Common Signs of Transmission Trouble

Book an inspection if you notice:

• Slipping gears or RPMs rising without acceleration

• Delayed engagement when shifting into Drive or Reverse

• Harsh shifting, clunking, or “bang” shifts

• Shudder/vibration during acceleration or lockup

• Burning smell or dark transmission fluid

• Transmission fluid leaks

• Check Engine Light / transmission warning messages

• “D” flashing or limp mode

• No movement in Drive or Reverse

 

What We Check During Transmission Diagnostics

Depending on your symptoms, our process may include:

• Scan for transmission-related codes and live data

• Road test to verify shift quality and operating conditions

• Transmission fluid level/condition check (and leak inspection)

• Electrical testing of related sensors, solenoids, wiring, and grounds (as needed)

• Verification of related systems that affect drivability (engine misfires, mounts, axle issues)

• Clear recommendations: urgent concerns vs. monitor/maintenance

 

Transmission Services We Offer

• Transmission diagnostics and drivability testing

• Transmission fluid service (where appropriate)

• Leak diagnosis and resealing (pan gasket, cooler lines, etc.)

• Solenoid, sensor, and external component replacement (as applicable)

• Cooling system checks for transmission temperature control

• Transmission rebuild coordination or replacement options (vehicle-dependent)

• Driveline checks related to vibration/clunks (mounts, CV axles, etc.)

Note: Not every transmission issue requires a rebuild. Many drivability complaints are caused by fluid condition, leaks, sensors/solenoids, or related components. That’s why testing first matters.

 

Why Early Diagnosis Saves Money

Catching problems early can help prevent internal damage and reduce the chance of complete failure. If a rebuild or replacement is the best option, we’ll explain the pros/cons clearly and help you choose the most cost-effective path for your vehicle and plans.

Transmission Replacements (New or Used)

If repair or rebuild isn’t the most cost-effective option, we can source and install replacement transmissions. We’ll help you choose the best route based on your vehicle, timeline, and budget, including:

• New transmission replacement (when available)

• Used transmission replacement (tested/verified options when possible)

• Related recommended items during install (as applicable): fluid, filter, seals, cooler lines, mounts, and programming/adaptations if required

We’ll explain the pros/cons of each option and provide a clear quote before any work begins.

Warranty Coverage: Replacement transmissions typically include supplier-backed warranty coverage. We’ll explain what’s covered, for how long, and any conditions before you approve the repair.
