why does my Alfa Romeo Giulia 952 (2016-Present) have transmission fluid on the garage floor?

Symptoms

• Transmission fluid puddle under the vehicle
• Low transmission fluid warning light illuminated
• Difficulty shifting gears
• Slipping transmission during acceleration
• Unusual noises during gear changes (grinding or whining)

Diagnostic Steps

1. Inspect the garage floor to identify the color and consistency of the fluid to confirm it is transmission fluid.
2. Check the transmission fluid level using the dipstick (if equipped) or the fill plug.
3. Visually inspect the transmission pan for signs of damage or leakage.
4. Examine transmission cooler lines for cracks or loose connections.
5. Inspect the transmission seals and gaskets for wear or damage.
6. Use a UV dye and black light to detect leak sources if the leak is not immediately visible.

Solution

1. Preparation

• Gather tools and parts needed.
• Ensure the vehicle is on a level surface and use jack stands for safety.
• Disconnect the battery to avoid any electrical issues.

2. Drain Transmission Fluid

• Place a drain pan under the transmission pan.
• Remove the transmission pan bolts using a socket wrench.
• Carefully lower the pan to drain the fluid completely.

3. Inspect and Replace Gaskets

• Remove the old gasket from the transmission pan.
• Clean the mating surfaces of the transmission and pan with a solvent to remove old gasket material.
• Apply a new gasket or RTV sealant as specified in the service manual.

4. Check and Replace Seals

• Inspect input and output shaft seals for leaks.
• If damaged, use a seal puller to remove the old seals.
• Install new seals by applying lubricant and pressing them into place.

5. Reinstall Transmission Pan

• Position the transmission pan back onto the transmission.
• Torque the pan bolts to manufacturer specifications, typically around 10-12 ft-lbs.
• Refill the transmission with the appropriate type of fluid through the fill plug or dipstick tube.

6. Test for Leaks

• Reconnect the battery and start the vehicle.
• Let it run for a few minutes and check for any leaks around the transmission pan and seals.
• Take the vehicle for a short test drive to ensure proper operation.
