The 2006 Mondeo requires 5 liters of transmission fluid. Below is an introduction to the Mondeo's features: 1. Exterior: The exterior design is attractive, with a solid feel typical of American cars. 2. Interior: The interior features a well-layered design, and Ford's materials are reliable. 3. Performance: The acceleration is responsive, and the power delivery remains stable at higher speeds. 4. Handling: The car has strong handling performance, with a comfortable and easy-to-control steering wheel, precise turning, and highly sensitive throttle and brakes. Below are the differences between the Mondeo and the Mondeo Zhisheng: 1. Drivetrain: The Ford Mondeo is front-engine, front-wheel drive; the Mondeo Zhisheng is front-wheel drive. 2. Transmission: The Ford Mondeo uses a SelectShift 6-speed automatic transmission; the Mondeo Zhisheng uses a Powershift 6-speed dual-clutch transmission. 3. Dimensions: The Ford Mondeo measures 4873mm in length, 1852mm in width, and 1470mm in height; the Mondeo Zhisheng measures 4854mm in length, 1886mm in width, and 1495mm in height. 4. Fuel consumption: The Ford Mondeo has a fuel consumption of 6.9 liters per 100 kilometers; the Mondeo Zhisheng has a combined fuel consumption of 7.9 liters per 100 kilometers.

I've been driving a 2006 Mondeo automatic for ten years and have changed the transmission fluid three times myself. In practice, preparing 5 liters of MERCON V standard fluid is sufficient. With a gravity drain, you can typically add about 4.2-4.7 liters. The key is to park the car on a level surface, remove the oil pan, and thoroughly clean out the metal shavings and old fluid. After draining the old fluid, add new fluid until it starts leaking from the overflow tube, then stop. Start the engine and shift through each gear to circulate the fluid, then top it up to the middle mark on the dipstick. Remember to check the fluid level when the car is warm for the most accurate reading—cold levels will be about 1 cm higher. Be careful not to overfill, as it can damage the transmission. I always replace the filter with each fluid change, especially since it's a 15-year-old car.

Last time at the repair shop, the mechanic was handling the transmission fluid for my '06 Mondeo. He mentioned that this generation's automatic models require 4.3-4.8 liters, depending on whether the oil pan is removed during draining. He emphasized using OEM MERCON V certified fluid and advised against mixing different brands. After the change, the vehicle needs to be started and shifted through gears for a few minutes before returning to check the fluid level. The technician specifically used an infrared gun to measure the fluid temperature to 60°C before checking the dipstick. Manual transmissions are simpler, requiring about 2.2 liters filled through the filler hole until it overflows. For a car that hasn't had a change in six years, it's best to prepare 5 liters in advance, as draining the old fluid completely takes some time.

My 2006 model with a 2.5L automatic transmission requires 4.5 liters of transmission fluid in actual testing. The sequence of operations is crucial: first remove the drain plug, then detach the oil pan to clean metal shavings from the magnet, install a new filter, and pour in 3 liters of new fluid. Start the engine, shift gears for 30 seconds to allow the fluid to circulate into the valve body, then turn off the engine and top up the remaining 1.5 liters. When the fluid temperature reaches 40°C, the fluid level should be at the upper edge of the mesh area on the dipstick. Last time, not replacing the filter caused unstable oil pressure—a lesson learned that the filter must be changed simultaneously. After the change, a noticeable reduction in downshift jerk was felt. Replacing it every 60,000 kilometers is the safest practice.

The auto repair shop owner recommends using a transmission flush machine for a more thorough oil change on the 2006 Mondeo, requiring 12 liters of transmission fluid, though 4.5 liters is sufficient for regular maintenance via gravity drain. Don't forget to check the oil pan gasket for deformation during the operation, as stripped screws are common in older cars. Last time I changed the oil, I found the drain plug magnet had collected quite a bit of metal debris, which can affect shifting precision. Manual transmission owners say 2 liters is enough, done through the fill hole near the wheel arch. It's advised to use OEM fluid to prevent clutch slippage. Cars that haven't had a fluid change in over three years should have their fluid quality tested.
