This fluid is usually red or brown. A burning smell from the transmission area can also be a clue, as it might mean fluid is dripping onto hot parts.When the transmission fluid is low, you might notice your car doesn't shift gears smoothly. It could delay or make strange shifts, especially when you speed up. You might also hear grinding or whining noises during gear changes, which means the transmission isn't getting enough fluid.Sometimes, your car might vibrate or not deliver power well to the wheels. This happens because the transmission isn't working efficiently due to low fluid levels.Check the fluid level and color with a dipstick. If the fluid is low or looks burnt, it might confirm a leak. Fixing these issues quickly can save you from bigger transmission problems.Gathering Necessary ToolsTo fix a leaking input shaft seal in a Ford transmission, you'll need some key tools.

A transmission jack will help you lower the unit safely.Separate Clutch or Torque Converter: If the vehicle has a manual transmission, remove the clutch assembly. If it's automatic, disconnect the torque converter. This lets you reach the input shaft seal without harming other parts.Remove the Bellhousing: Once the transmission is out, take off the bellhousing. This gives you a clear view of the input shaft and seal. Keep the bolts in order for when you put everything back together.Replacing the Input Shaft SealAfter taking off the bellhousing, you can see the input shaft seal. To remove the old seal, use a seal puller or a flathead screwdriver. Be gentle to avoid scratching the surrounding areas.

Remove any dirt or leftover transmission fluid. This will help when putting in the new seal.Choose a good replacement seal, ideally one that matches the original. Place the new seal on the input shaft. Use a seal driver or a similar tool to press it in evenly. This will help it fit snugly and stop leaks.Make sure the seal sits evenly. This will prevent uneven pressure that can cause it to fail early. This step-by-step process will help keep the transmission working well.Testing and Final ChecksAfter replacing the seal, it's time to check if the repair is good. Look around the input shaft for any leaks. This confirms the seal is placed right and the fluid levels are steady.Here are the steps to test the repair:Start the Car: Let it run until it warms up. Watch the transmission area for any fluid leaks. This checks if the seal handles heat well.Drive the Car: Take it for a drive at different speeds and on various roads. This checks if the seal stays strong when the car is moving and under pressure.Check Fluid Levels Again: Once you park the car on a flat spot, look at the transmission fluid level. If the level hasn't changed, the seal is working.These steps help make sure the seal replacement was done right, keeping the transmission running smoothly.People Also AskHow Much Does It Typically Cost to Repair a Leaking Input Shaft Seal?Fixing a leaking input shaft seal in a Ford transmission usually costs between $400 and $800.
