🔧 Kona - Transmission Fluid Change

Your Kona’s dual-clutch transmission uses a specific DCT fluid and a temperature-based level check. If the fluid level is set wrong (too high or too low), shifting problems and damage can happen.

Before I give the exact step-by-step (with correct plugs, fluid spec, and torque specs), I need 2 quick details so I don’t steer you wrong.

Difficulty Level: Advanced | Estimated Time: 1.5-3.0 hours

⚠️ Safety & Precautions

• ⚠️ Work on a level surface; the DCT fluid level check depends on the car being perfectly level.
• ⚠️ Use jack stands (never rely on a jack alone).
• ⚠️ Transmission/exhaust parts can be hot; let the car cool first.
• ⚠️ Keep the area very clean; dirt in a DCT can cause shifting issues.
• ⚠️ Battery disconnect is usually not required for a fluid drain/fill, but keep the key away from the car while under it.

📋 Before You Begin

• Park your Kona on a level surface and place wheel chocks behind the rear wheels.
• Raise and support the vehicle so it sits level on jack stands.
• Have your OBD2 scan tool ready—DCT fluid level is set at a specific temperature window.
• 2 quick questions (reply with A/B):
  A) Are you doing a simple drain-and-fill, or are you trying to do a full flush?
  B) Do you have an OBD2 scan tool that can read transmission fluid temperature on your Kona?

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Pause here so we use the correct procedure

• Because your Kona has a dual-clutch transmission, the fill/level-check method and correct plugs depend on the exact service type (drain/fill vs flush) and whether we can verify fluid temperature.
• Reply with your answers to the two questions above, and I’ll give you the exact, Kona-specific steps including the correct fill point, level-check temperature window, and Torque to XX Nm (YY ft-lbs) specs.

✅ After Repair

• Once the level is set correctly, do a short test drive and confirm normal shifting.
• Recheck underneath for leaks after the drive.
