Can changing manual transmission fluid be bad?
Many mechanics believe, perhaps correctly, that if you wait too long (mileage, not color) you should not change the fluid because it could cause transmission failure prematurely; whereas if you had changed it regularly all along it would be ok.
When should manual transmission fluid be changed?
Most manufacturers recommend that manual transmission fluid be changed every 30,000 to 60,000 miles. Under heavy-duty use, such as towing or stop-and-go traffic, some manufacturers suggest changing transmission fluid every 15,000 miles.
How much does it cost to change manual transmission fluid?

Can you mix old and new transmission fluid?

What fluid do you use for a manual transmission?
Commonly recommended manual transmission fluid formulations include SAE 80W, 75W-90, 80W-90 and SAE 90. In some cases, a multi-grade engine oil or automatic transmission fluid may be recommended. However, a manual transmission fluid is typically the most optimal for manual transmissions.
Should I change manual transmission fluid after 100k miles?
Do You Need to Have the Transmission Fluid Changed? The simple answer is yes. But service intervals for new vehicles can exceed 100,000 miles before this needs to be done. That makes this seemingly clear-cut advice something of a conundrum for car owners.
Should I change manual transmission fluid after 150k miles?
The manufacturer’s maintenance schedule for many automatic transmissions doesn’t call for fresh fluid until 100,000 miles or, with some Ford transmissions, even 150,000 miles. A lot of mechanics say that is too long and that it should be done at least every 50,000 miles.
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.
How do you know if your gearbox oil needs changing?
