How often do you change the transmission oil?

The transmission fluid in an automatic transmission will typically need to be changed out every now and then. The same is usually true for transmission oil in manual transmissions. However, speaking very generally, transmission oil changes are needed less frequently than transmission fluid changes.

What should you do when you change transmission fluid?

Dispose of the fluid properly. Transmission fluid is harmful for the environment, and it’s important that you avoid draining or dumping transmission fluids into the environment. Always wear gloves and wash your skin of any residue immediately after completing the change of fluids.

What causes transmission fluid to deteriorate over time?

Aging transmission fluid can easily deteriorate under the extreme heat generated by the transmission itself. In most cases, the internal temperatures within an automatic transmission are up to 150 degrees higher than engine temperatures. The transmission fluid contains grit and debris.

Why is there grit in the transmission fluid?

The transmission fluid contains grit and debris. Finding metal debris in the transmission fluid is a definite sign of the major component that’s on its way out. That grit seen in old transmission fluid is actually bits of metal that has worn off the gears and clutches within the transmission.

How often should you change your transmission fluid?

Manual: Most manufacturers recommend that manual transmission fluid be changed every 30,000 to 60,000 miles. Under heavy-duty use, some manufacturers suggest changing transmission fluid every 15,000 miles. Automatic: Service intervals for an automatic transmission vary from every 30,000 miles to never.

How much does it cost to change the transmission fluid?

The average cost for a transmission fluid change is between $172 and $199. Labor costs are estimated between $99 and $126 while parts are priced at $73.

When not to change transmission fluid?

Most mechanics don’t recommend not having the transmission fluid changed at least once every 100,000 miles , though, but some vehicles’ owner’s manuals don’t even contain a section about such changes altogether. This is especially common in complex vehicles such as BMW and Mercedes models.

Is changing transmission fluid bad?

Changing transmission fluid is never a bad thing, but if you’ve never had the service performed over the life of the vehicle, or have neglected the service while doing hard driving, then the suspended metal particles from wear might be just enough to maintain friction within the clutch pack to move the truck.
