As gears are in a constant mesh even whilst in neutral, engine oil will not lubricate constant mesh gears, it’s just not thick enough and would soon breakdown and the gearbox would prematurely wear out. On the reverse side, engine oils is too thick to be used in an automatic transmission.
Can an oil change cause a transmission problem?
Many of these issues can occur following an oil change even if it was done by a mechanic. Transmission fluid tends to have a sweeter smell, but will smell distinctly “burnt” if there is an issue. Leaks from other fluids may cause a burning smell if they leak into or onto the engine.
Can low oil affect shifting?
Transmission oil/fluid that is low, dirty or the wrong fluid can also cause this problem in manual transmissions. A clutch pedal that engages very low is typically a problem with the linkage or hydraulic system that operates the clutch.
What does motor oil do to a transmission?
The function of motor oil is to enhance sealing, keep the engine cool, protect against rust and corrosion, keep the engine parts free of sludge, and to lubricate the moving parts of the engine. On the other hand, the main function of transmission fluid is to impart power to the automatic transmission.
Why you should never change transmission fluid?
If you don’t change your transmission fluid frequently, the dirty fluid will not serve as an effective lubricant and it won’t disperse heat well. This will cause wear and tear on the clutches and other parts of your transmission.
What are symptoms of dirty transmission?

What happens if gear oil is low?
A healthy transmission will shift between gears smoothly and there won’t be any slippage. Low fluid levels can cause gears to miss, which will result in a grinding sensation.
Can a transmission go out without warning?
Luckily, transmission failure doesn’t usually happen without warning. There are several warning signs that your transmission’s going out.
What causes delayed shifting in a automatic transmission?
Delayed shifting is often caused by valves sticking the valve body, which prevents shifts from happening when they should. On newer cars, which control shifts using a computer, the problem could lie in the shift solenoids that are used to trigger shifts.
What happens if you put motor oil in the transmission by mistake?
Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.
Is transmission oil the same as oil change?
A transmission fluid change is the same as an oil change — only it involves transmission fluid rather than engine oil. During a transmission fluid change, the mechanic will place a large pan underneath your vehicle’s transmission and then remove the drain plug to drain the fluid.
Is engine oil the same as transmission oil?
A couple of differences are the following: Motor oil is designed to deal with the products of combustion, whereas automatic transmission fluid (ATF) does not see contaminants from fuel burning. … Transmission fluid is also used by your steering system to keep its parts moving smoothly.
Is it bad to change transmission fluid on high mileage?
Changing the transmission fluid on a high-mileage car is risky. Don’t do it unless your transmission is running fine and the fluid is first-rate, because it can make transmission failure imminent.
How often should I change my transmission oil?
Most manufacturers recommend replacing transmission fluid every 30,000 to 60,000 miles. If you tow, or do mostly city driving with constant changes of gears, it may be wise to change your ATF even more often. Here’s why. Your automatic transmission has a lot of moving parts.
Is it OK to change transmission fluid after 100k miles?
The simple answer is yes. But service intervals for new vehicles can exceed 100,000 miles before this needs to be done. … Those who don’t hold on to a new vehicle for very long may never have to have the transmission fluid changed.
