Of course, it is risky to change transmission fluid if you drive a high-mileage car. Although it is vital to change your vehicle’s transmission fluid periodically; but, if your vehicle has high mileage and it’s still running using the transmission oil from the factory, it would be best to let it be.
Can changing old transmission fluid be bad?
As the oil gets old, it becomes thicker and becomes less slippery. Sometimes this extra friction from the old oil is what keeps the clutch working properly. The problem arises when a fresh trans fluid is added to the worn out transmission- The clutch might start slipping or the car might refuse to shift out of gear.
Should I change my transmission fluid at 90000 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.
Is there high mileage transmission fluid?
High Mileage Automatic Transmission Fluid is a premium ATF specially formulated for maximum transmission life in high mileage vehicles. High Mileage ATF has been engineered to help alleviate typical problems experienced by transmissions with over 75,000 miles such as leaks and rough shifts.
Related Question Is it bad to change transmission fluid on high mileage?
Will I notice a difference after changing transmission fluid?
All the old, dirty fluid is removed and replaced with fresh, high-quality fluid. You'll also notice smoother, more consistent shifting since the new fluid will provide more effective frictional properties.
Is it worth changing transmission fluid?
Many manufacturers don't recommend changing your transmission fluid until the 75,000-100,000 mile mark. Performing regular fluid maintenance on your transmission is the best way to extend the life of that transmission, making them well worth the cost.
Should transmission fluid be changed?
If you drive manual, most manufacturers will recommend changing your transmission fluid every 30,000 to 60,000 miles. If you have automatic, you can typically boost that range up to 60,000 to 100,000 miles. There's no harm in changing your fluid early.
When should transmission fluid be changed?
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.
Should I change my transmission fluid if it's black?

A typical transmission flush will cost around $150. A transmission flush on smaller cars may cost in the low $100s while it may cost more than $200 on larger vehicles. A good rule of thumb is that a flush costs about twice as much as a fluid change.
What happens when transmission fluid is high?
If you add too much transmission fluid, you will notice that it may foam, and that can bring about erratic gear shifting. Some other problems that may arise include oil starvation and transmission damage. Adding too much transmission fluid can also cause early failure and damage of parts as result of excess pressure.
