Can You Repair a Transmission By Yourself? | Stonum Automotive - Longmont, CO (2024)

At Stonum Automotive, we know that the transmission is an essential yet complex part of your vehicle’s mechanics. For many car enthusiasts, the idea of repairing a transmission themselves might be as daunting as it is intriguing. In this extensive guide, we will explore the ins and outs of transmission repair, providing both the knowledge and confidence necessary to tackle this task head-on, or to know when it’s best to steer toward professional help.

Understanding Transmission Systems

Understanding the fundamentals of the transmission system is crucial before making any repairs. Transmissions move power from the engine to the wheels by changing gears automatically or manually.

Components of a Transmission

The transmission consists of various parts, including:

• Clutch: Engages and disengages the engine from the rest of the drivetrain.
• Gears: Varying sizes of gears create speed ratios between the engine and the driveshaft.
• Shafts: Transmit power from the engine to the wheels via gears.
• Torque Converter (Automatic Transmissions): Uses fluid to transmit power from the engine to the transmission.

Common Car transmission Issues Requiring Repair

Transmissions can experience a range of issues, some more common than others:

• Slipping Gears: Characterized by an unexpected change in acceleration without changing gears manually
• Rough Shifting: When the gear changes are accompanied by a noticeable jolt.
• Noisy Transmission: Unusual sounds such as whining, clunking, or humming during operation.
• Leaking Transmission Fluid: Often indicated by a pink or reddish pool under the car.
• Burning Smell: Indicates that the transmission is overheating or there is a mechanical issue.

DIY Transmission Repair Tips

Fixing your transmission can save money, but it’s a big job. Here are some tips to help you through the DIY process.

Tools Needed

For basic repairs, you will need tools such as:

• Socket Set
• Torque Wrench
• Hammer
• Pry Bars
• Hydraulic Jack
• Transmission Jack (for transmission removal, in some cases)

Step-by-Step Guide

If you decide to repair your transmission, here’s a general guide to follow:

1. Diagnostic: Identify the specific problem through observing symptoms and performing tests.
2. Prepare the Vehicle: Ensure the car is turned off and safely lifted, with proper access to the transmission.
3. Disassembling the Transmission: This involves careful step-by-step disassembly of the transmission, often requiring you to remove other parts of the vehicle as well.
4. Repair/Replace Damaged Parts: Depending on the problem, you’ll either need to repair the part or replace it with new components.
5. Reassembling the Transmission: This should be done meticulously, ensuring the part fits correctly and all connections are secure.
6. Refill Fluid and Test Drive: After reassembly, refill the transmission with the correct fluid and test it to ensure the issue is resolved.

When to Seek Professional Help

While the allure of DIY repair is strong, there are situations where professional help is absolutely vital.

How Much Does Transmission Repair Cost?

The cost comparison between DIY and professional repairs is a significant factor in many car owners’ decisions.

DIY vs. Professional Repair Costs

Fixing your own transmission can save money on labor, but you’ll need to spend it on tools and parts. Professional services at Stonum Automotive may cost more, but we provide expertise and a guaranteed transmission repair.

Factors Influencing Repair Costs

Several factors can influence the overall cost of transmission repair, including:

• Severity of the Issue: A minor issue will cost less to repair than a major one.
• Vehicle Type and Age: Newer or luxury vehicles often have higher repair costs due to the complexity of their transmissions.
• Parts and Fluids: The quality and type of parts and fluids will impact the repair cost.

How Long Does a Transmission Repair Take?

The time it takes to fix a transmission can vary a lot. It depends on how bad the problem is and if you’re doing it yourself or getting help from experts. For simpler problems, such as replacing fluids or fixing minor leaks, the repair might only take a few hours.

Fixing more difficult problems may take a few days, especially if parts need to be ordered for repair or replacement. Experts can fix things faster with their skills and tools, but repairs still usually take 2 to 5 days. Always prioritize thoroughness and precision over speed when repairing a transmission to ensure its longevity and proper functioning.

Does Auto Insurance Cover Transmission Repair?

One common question we encounter from vehicle owners is whether auto insurance will cover the costs of transmission repair. The answer depends largely on the nature of your auto insurance policy and the cause of the transmission damage.

Basic car insurance policies usually don’t pay for fixing transmission problems caused by regular use or mechanical issues. However, if your transmission damage is the result of an accident, collision coverage may contribute to the repair costs. If something like a flood, fire, or vandalism causes damage, comprehensive coverage could help with the costs.

For those seeking more extensive protection, some insurance companies offer mechanical breakdown insurance (MBI), which is designed to cover the cost of repairs not related to an accident, including transmission repairs. MBI policies, though not universally available, can be a lifeline for those facing unexpected mechanical failures.

It’s important to review your policy details and speak with your insurance provider to understand what is and isn’t covered. Knowing where you stand can help you plan financially for any potential transmission repairs or other major vehicular issues that may arise.
