Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues.

2. Identify the Leak Source

Tools Required: Flashlight, rags
Use a flashlight to inspect the transmission pan and surrounding areas for the source of the leak.
Clean any fluid residue to identify fresh leaks more easily.

3. Replace Transmission Pan Gasket or Pan (if necessary)

Tools Required: Socket set, torque wrench, gasket scraper
Drain the transmission fluid from the pan by removing the drain plug or pan bolts.
Remove the transmission pan and old gasket.
Clean the mating surfaces thoroughly with a gasket scraper.
Install a new gasket or pan, ensuring proper alignment.
Reinstall the pan bolts to the manufacturer’s torque specifications (typically around 10-12 Nm).

4. Repair or Replace Damaged Lines/Seals

Tools Required: Wrench set, hose clamps (if applicable)
If the cooler lines are leaking, disconnect the damaged line using the appropriate wrench.
Replace the line with a new one and secure it with hose clamps as needed.
For leaking seals, remove the affected component (input/output shaft) and replace the seal using a seal puller if necessary.

5. Refill Transmission Fluid

Tools Required: Funnel, transmission fluid (specific to Renault specifications)
Use a funnel to refill the transmission with the appropriate type and amount of fluid as per manufacturer specifications.
Check the fluid level using the dipstick and add more if necessary.
