- Overheating⁚ Improper maintenance, low fluid levels, or a faulty cooler can lead to overheating.
- Solenoid problems⁚ Solenoids control fluid flow and can malfunction, causing shifting issues.
Diagnosing Transmission Issues
Diagnosing transmission problems requires careful inspection and testing. A mechanic can use a scan tool to retrieve diagnostic trouble codes (DTCs) from the TCM, providing insights into potential issues. Additionally, they can inspect fluid levels, check for leaks, and perform a road test to assess the transmission’s performance.
