⚡ Common Causes

›Failed shift solenoid
›Dirty transmission fluid clogging solenoid
›Wiring fault to solenoid
›Low transmission fluid pressure
›Internal valve body fault

⚠️ Symptoms

›Transmission stuck in gear
›Harsh or no shifting
›Check engine light
›Limp mode

✅ How to Fix — Step by Step

Step 1:Check transmission fluid level and condition
Step 2:Service transmission fluid and filter
Step 3:Test solenoid resistance (20–30 ohms typical)
Step 4:Replace shift solenoid A
Step 5:Inspect valve body for wear

💡 Pro Tip: Always service the transmission fluid before replacing solenoids — dirty fluid is the leading cause of solenoid failure.
