•Unusual burning smell from the transmission area

•Fluid leaks or discoloration noticeable under the vehicle

•High engine RPMs without corresponding acceleration

•Overheating engine temperature gauge

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool if it has been running.

2. Check and Replace CVT Fluid

Tools Required: Socket set, funnel, new CVT fluid (consult owner's manual for specifications).
Sub-steps:
1. Locate the CVT fluid dipstick (if applicable) and remove it.
2. Wipe the dipstick clean and reinsert it to check the fluid level.
3. If the fluid is low, add the appropriate CVT fluid using a funnel until it reaches the correct level.
4. If the fluid is discolored or burnt, drain the old fluid through the drain plug (if equipped) and replace it with fresh CVT fluid.

3. Inspect and Repair Cooling System

Tools Required: Pressure tester, hose clamp pliers.
Sub-steps:
1. Inspect the radiator and cooling lines for any obstructions or leaks.
2. Use a pressure tester to ensure the cooling system holds pressure without leaking.
3. Replace any damaged hoses or components as necessary.

4. Address Electrical or Sensor Issues

Tools Required: Multimeter.
Sub-steps:
1. Inspect transmission temperature sensors for proper connection and functionality.
2. Test the sensors with a multimeter to ensure they are providing accurate readings.
3. Replace any faulty sensors to ensure proper monitoring of transmission temperature.
