Comprehensive Transmission Performance Check at Milex - Mr. Transmission of Cary
At Milex - Mr. Transmission of Cary, we provide a free Performance Check to accurately diagnose potential transmission issues in your vehicle. Our thorough inspection process includes a fluid check, road test, diagnostic trouble code scan, and bay inspection, ensuring a detailed evaluation of your transmission’s condition and overall vehicle performance.
What Does a Performance Check Include?

Fluid Check – Identifying Transmission Health
One of the first indicators of potential transmission issues is fluid condition. A healthy transmission will have clear, red fluid. During our fluid inspection, we assess its clarity, consistency, and odor. Discolored or burnt-smelling fluid may indicate internal damage, signaling the need for further investigation. Low fluid levels can also contribute to transmission slipping, overheating, and premature wear.

Road Test – Assessing Shifting Performance
Our road test consists of two key evaluations: a stationary test and a driving test. These tests help detect transmission problems such as:
- Slipping gears
- Harsh, soft, or erratic shifting
- Delayed or early shift patterns
- Unusual noises such as grinding or whining
- Hesitation when accelerating
Unusual sounds or performance irregularities can be early warning signs of transmission failure, making road testing a critical part of our Performance Check.

Bay Inspection – Evaluating Transmission Components
Our bay inspection is designed to pinpoint any necessary adjustments, repairs, or replacements. One of our expert technicians will inspect:
- Manual linkage
- Engine and transmission mounts
- U-joints and CV axles
- Fluid retention and potential leaks
- Electronic components, sensors, switches, and solenoids
If we detect transmission damage or component failure, we will recommend the next best course of action to prevent further issues. Addressing minor concerns early can help prevent costly repairs and extend the life of your transmission.

Diagnostic Trouble Code Scan – Pinpointing Hidden Issues
Modern vehicles use onboard diagnostic systems (OBD) to track transmission performance. Our technicians check for diagnostic trouble codes (DTCs), which reveal specific malfunctions in your transmission or related systems. If internal issues are suspected, we may suggest a comprehensive internal transmission inspection to determine the extent of the problem.

Next Steps After a Performance Check:


Regular transmission maintenance can prevent costly repairs and keep your vehicle running smoothly. Our team will replace your transmission fluid and filter (if applicable) to ensure optimal lubrication and cooling, reducing unnecessary wear on components.

If your transmission issue is minor, we may recommend external adjustments or repairs that do not require transmission removal. This can include simple fixes such as linkage adjustments, replacing faulty sensors, or addressing minor electrical issues that could be impacting shifting performance.

If we find your transmission is leaking but has no internal damage, a reseal service may be necessary. This requires removing the transmission to replace leaking external seals, ensuring proper fluid retention. Left unchecked, fluid leaks can lead to overheating and severe damage over time.

For more serious transmission concerns, an internal inspection is required. Our experts remove and disassemble your transmission to inspect all internal components for damage. Any necessary parts will be replaced using OEM-quality parts to restore optimal performance. After repairs, the transmission is carefully reinstalled and tested to ensure it meets factory performance standards.
