How long should transmission fluid last?
If fluid temperatures can be held to 175 degrees F., ATF will last almost indefinitely — say up to 100,000 miles. But if the fluid temperature goes much higher, the life of the fluid begins to plummet. The problem is even normal driving can push fluid temperatures well beyond safe limits.
Will changing transmission fluid help shifting?
