How We Handle Every Transmission Service
Every transmission job at Christian Brothers Automotive Weldon Spring follows the same straightforward process, whether it’s a routine fluid exchange or a more involved repair.
Inspect & Diagnose
We start with a thorough inspection, testing transmission components and reviewing any symptoms you’ve noticed. Our certified technicians document what they find and identify anything safety-critical before recommending next steps.
Explain & Get Your Approval
We present a clear estimate and walk you through the findings before any work begins. You decide what to address now and what to plan for later. Nothing moves forward without your sign-off, and if the scope changes, we call you first.
Complete the Repair
Once you’ve approved the work, our team completes the repair using manufacturer-quality equipment. Our goal is to get it done right the first time so you can drive away with confidence.
1. Schedule Your Appointment
Whether scheduling online or over the phone be sure and let us know what you're experiencing so we can provide fast and accurate service advice.
2. Diagnostics and Inspections
Drop off your vehicle and the shop will get to work with inspections and diagnostics using the same equipment as the manufacturers to determine issues and next steps.
3. Digital Vehicle Inspection Report and Estimate
Following the diagnosis we will text you a digital vehicle inspection report, containing pictures and videos of our findings and recommendations.
4. Review and Approval
A service advisor will reach out to walk you through the findings and recommendations to determine how you would like to proceed, or you can approve work directly in your DVI.
5. Work Performed or Scheduled
Most work can be completed immediately, or scheduled based on parts and customer availability.
The Nice Difference® Warranty on Transmission Repairs
Most automotive warranties expire at whichever mileage or time limit arrives first. Our Nice Difference® warranty works differently: coverage lasts for 3 years or 36,000 miles, whichever comes last. That structure gives drivers with varying mileage patterns a broader protection window than the standard shop ceiling.
The warranty is honored at any Christian Brothers Automotive location nationwide, not just the shop where the original repair was done. And if you carry an existing extended warranty, we work with all major extended warranty providers.
Transmission Health: What O’Fallon Drivers Should Know
Transmission problems rarely appear without warning. Catching the early signs gives you options before a manageable issue becomes a much costlier one.
Warning Signs That Warrant a Diagnostic Visit
Several symptoms can signal a transmission problem that needs professional attention:
- Grinding or whining when shifting can point to internal wear in the transmission
- A burning smell from the vehicle may indicate overheating transmission fluid
- Fluid spots on the driveway are a common sign of a failing seal or gasket
- Delayed, erratic, or slipping gear changes suggest mechanical or electronic problems inside the transmission
- A vehicle that refuses to shift or pops out of gear requires prompt diagnosis
- Reduced fuel efficiency can result when a struggling transmission forces the engine to work harder
If you’re noticing any of these, the earlier you bring the vehicle in, the more options you’ll have.
Routine Maintenance & Full-Service Transmission Repair in O’Fallon
Routine transmission maintenance is generally recommended every 30,000 to 60,000 miles, though the right interval depends on your vehicle’s make, model, and how you drive. Frequent stop-and-go traffic, towing, and other high-demand conditions can shorten that window. Regular transmission fluid exchanges help maintain performance and reduce the risk of more costly repairs down the line.
At Christian Brothers Automotive Weldon Spring, we handle the full scope of Transmission Services for both automatic and manual transmissions across all vehicle makes and models, including foreign and domestic cars, trucks, and SUVs. That includes diagnostic checks, fluid exchanges, complete overhauls, and replacements. When a transmission can’t be repaired, we can walk you through your replacement options, including the differences in reliability, warranty coverage, and cost, so you can make a decision that fits your situation.

FAQs
-
Q. "What factors determine the price of transmission repair?"Many different factors go into determining costs of transmission repair. The major factor is what type of vehicle you drive. The year, make and model of the car, determine how much parts and labor will cost. Another factor is how much damage the transmission has sustained. Your transmission should last a minimum of 100,000 miles by servicing your transmission on a regular basis.
-
Q. "What does automatic transmission service include?"Fluid is first drained from the pan during an automatic transmission service. A new transmission filter is installed with a new pan gasket once the pan has been removed. Finally, fresh automatic transmission fluid (ATF) is used to refill the vehicle.
-
Q. "Is there a difference between a transmission fluid change and flush?"During a transmission fluid and filter change, it’s only the fluid in the pan that is drained and replaced with new ATF. Four to five quarts of fluid will typically be replaced in this process, while nine to thirteen quarts are replaced during a full transmission fluid flush. The difference in amounts is because the complete flush drains the entire system.
