### **Cons of the GM 4T65E Transmission (Clutch Thrust Washer Issue)**
1. **Clutch Thrust Washer Wear (Common Failure Point)**
- The **clutch thrust washer** (part numbers **19125902** and **24204847**) is a **friction-based component** that can wear out over time, leading to:
- **Slipping clutches** (especially in **3rd and 4th gears**).
- **Delayed or rough shifts**.
- **Excessive clutch plate wear**, requiring more frequent **clutch kit replacements**.
- This issue is **more common in high-mileage vehicles** or those with **poor maintenance history**.
2. **Fluid Degradation & Contamination**
- The **4T65E** is **sensitive to fluid quality**. Old or degraded fluid can cause:- **Slipping under load**.
- **Burning smells** (indicating overheating).
- **Internal component wear** (solenoids, bands, and clutches).
- Many owners **underestimate the importance of fluid changes**, leading to premature failure.
3. **Solenoid & Valve Body Failures**
- The **4T65E s valve body and solenoids** can fail over time, causing:- **Stuck shifts** (e.g., permanent 3rd gear).
- **No reverse or delayed engagement**.
- **Electrical issues** (if solenoids burn out).
- While repairable, **valve body replacements** can be **costly** ($500 $1,200 ).
4. **Torque Converter Issues**
- Some **4T65E applications** (especially in **high-torque engines**) suffer from:- **Torque converter stall speed issues**.
- **Slipping under heavy load**.
- **Requiring frequent torque converter replacements** (a **$500 $1,000 ** repair).
5. **Seal & Gasket Leaks**
- The **4T65E** is prone to **fluid leaks** from:- **Front seal** (common in high-mileage units).
- **Rear main seal** (if the transmission is overhauled improperly).
- **Valve body gaskets** (leading to external leaks).
- Leaks can cause **low fluid levels**, leading to **premature wear**.
6. **Electrical & Sensor Problems**
- Some **4T65E models** (especially those with **PCM upgrades**) may experience:- **Transmission control module (TCM) failures**.
- **Speed sensor issues** (causing rough shifts or no shifts).
- **Compatibility problems** with modern ECUs in modified vehicles.
7. **Rebuild Costs Can Be High**
- While **cheaper than new transmissions**, a **full rebuild** (including **clutch kits, bands, solenoids, and seals**) can cost:- **$1,200 $2,500 ** (labor-intensive).
- **$800 $1,500** for a **DIY rebuild** (if skilled).
- **Clutch thrust washer replacement alone** may not be enough **full clutch kit replacement** is often recommended.

### **Conclusion**
The **GM 4T65E transmission** is a **capable and durable** automatic transmission when **properly maintained**. However, its **clutch thrust washer and related clutch issues** (especially in high-mileage vehicles) can lead to **costly repairs** if neglected. The **4T65E excels in applications where reliability and modifiability are prioritized**, such as **classic cars, muscle cars, and performance builds**, but it requires **strict maintenance** to avoid premature failure.
If you are considering a **vehicle with a 4T65E**, especially one with **clutch thrust washer concerns**, you should:- **Check maintenance records** (fluid changes, rebuild history).
- **Inspect for leaks, slipping, or rough shifts**.
- **Budget for potential clutch kit and solenoid replacements**.
- **Consider a rebuild or upgrade** if the transmission is **high-mileage and showing wear**.
For **daily drivers**, a **newer transmission (6-speed or 8-speed)** may be a **more hassle-free** choice, but for **enthusiasts and those who enjoy working on their vehicles**, the **4T65E remains a strong and modifiable option** when cared for properly.
---
### **Final Recommendation**
