A transmission replacement can sound scary, but it does not have to be confusing. If your car is slipping gears, shaking, or not moving the way it should, a new transmission may be the safest fix. Knowing what happens at the shop can help you feel ready and calm, especially if you have an extended warranty. Here is what to expect during a transmission replacement at a San Antonio repair shop.
Step 1: Full Diagnosis Comes First
A good shop will not replace a transmission unless it is truly needed. The first step is a full check of your vehicle. Technicians may test-drive your car, scan for trouble codes, and inspect the fluid, leaks, and how the transmission is working. Sometimes the problem is not the full transmission. It could be a sensor or an electrical part that costs less to fix. The goal is to find the real cause before doing major work.
Step 2: Clear Estimate and Plan
After the shop confirms the problem, they will explain your options. You should get a written estimate showing parts, labor, and how long the job should take. The shop should also tell you if a new, rebuilt, or remanufactured transmission is best for your car and budget. This is your time to ask questions and make sure everything is clear.
Step 3: Extended Warranty Approval Process
If you have an extended warranty, this step matters a lot. Most warranty companies need:
- A confirmed diagnosis
- Photos or inspection notes
- A call from the repair shop
- Approval before any work starts
A trusted shop will handle this for you. The team will contact your warranty company, send the needed paperwork, and speak with the adjuster. Sometimes the warranty company sends an inspector to double-check the issue. During this process, the shop should keep you updated so you know what is happening.
Step 4: Removal and Replacement
Once the warranty is approved, the work begins. The old transmission is removed carefully. The team disconnects parts like the battery, mounts, cooling lines, driveshaft, and wiring. Then the new or rebuilt transmission is installed. Fresh fluid is added, and the system is set up the right way. If other parts need replacing, like seals or filters, the shop handles that too, based on warranty rules and your car’s condition.
Step 5: Testing and Final Checks
Before you get your car back, the shop will test everything. They check for leaks, make sure shifting feels smooth, and take the car on a road test. This helps confirm the new transmission works the way it should.
