If you’re adding transmission fluid to a vehicle that’s in neutral and has been running for a while, then we recommend turning off the engine.
This is because it’s possible for some of the transmission fluid to be sucked back into the motor when the engine is off, which will cause problems with your transmission.
If you’re adding transmission fluid to a vehicle that isn’t running when you start adding the fluid, there’s no need to turn off the engine just be sure that all of your windows are rolled up and closed so no fluid can get inside.
Why should you not leave the car running when adding transmission fluid?
A car’s transmission fluid is a vital part of the engine, and it needs to be replaced when it gets too old.
If you leave the car running while you add transmission fluid, you run the risk of overheating your car’s engine.
This can cause serious damage over time, including reduced fuel efficiency and worse.
If you want to avoid damaging your car’s engine, don’t leave it running while adding transmission fluid.
Running a car while adding transmission fluid can make it difficult to judge how much fluid has been added.
You might end up overfilling or underfilling the transmission by mistake.
Some transmission fluids contain harsh chemicals that can damage your car’s paint if they spill on it while you’re filling up the transmission!
Leaving a car running while adding transmission fluid can cause problems with your engine’s emissions system which could lead to fines from your local environmental agency!
How do you add transmission fluid to a car that doesn’t have power steering?
Park your vehicle in a level space, with the wheels pointed straight ahead, and the emergency brake engaged.
Make sure the vehicle is turned off, and all electrical accessories are off as well.
Open the hood of your vehicle and locate the dipstick for the transmission fluid reservoir.
It’s usually on the driver’s side of the engine compartment, tucked away behind some hoses or wires.
Remove the cap from the transmission fluid reservoir and wipe it clean with a paper towel or rag before removing it completely from its housing in order to prevent contamination by dust or dirt particles while you’re doing this procedure.
If there are drips or leaks already present when removing this cap then call us immediately because we need to come out right away and fix whatever problem caused this leak.
Why do you need to add it?
Transmission fluid lubricates the gears in your transmission, allowing them to move smoothly and easily.
If your transmission fluid becomes too low, there’s a good chance that you’ll have trouble shifting gears or that your car won’t start at all.
The pros of leaving the car
The pros of leaving your car running while you add transmission fluid are pretty clear. For one thing, it’s a good way to keep warm. If your car has been sitting outside in the winter, it can get cold!
Another pro is that if your car’s engine is warm, it will help you avoid stripping any threads on the transmission pan.
Leaving your car running while adding transmission fluid is a great way to reduce the risk of spilling anything and making a mess in your driveway or garage.
What’s the best way to add transmission fluid?
The best way to add transmission fluid is to make sure you have the right kind of fluid. For most vehicles, this means a synthetic blend.
Check the level of your transmission fluid regularly, especially if you’ve recently added some.
Make sure that the dipstick is clean and then pull it out of the hole.
The level should be between MIN and MAX lines on the dipstick without being overfilled or underfilled.
Conclusion
You should not leave your car running when adding transmission fluid.
This can result in a number of problems, including engine damage and transmission failure.
