transmission flush


There are many routine services recommended for your vehicle that improve the life and drivability while the miles add up on your vehicle. One of these is the transmission flush. There has been much debate over the necessity of flushing the transmission fluid and whether it helps or hurts the transmission. If a transmission flush is done correctly and on time, flushes have an array of benefits and can help prevent transmission failure which is one of the most significant auto repair items.

Flushes are meant to be preventative maintenance and not a repair. This means if you are beginning to feel your transmission slip or it has a leak, a flush will not resolve these issues. A transmission flush is a recommended service every 30,000-50,000 miles on most vehicles to help keep your transmission healthy. Transmission fluid is an essential lubricant and it also serves as a coolant.

Another source of debate is whether to flush the transmission or simply drop the pan and drain out the fluid. By only dropping the pan, it leaves the job only partially done because it leaves used fluid in many areas: the cooling lines, the transmission cooler inside the radiator, the torque converter, and the internal transmission circuits. This means only about 25% of the used fluid is replaced. Transmission flushes, on the other hand, removes virtually all the used fluid making it much more effective and your vehicle gets fresh, clean transmission fluid.

There are also several benefits to flushing your transmission fluid with cleaners. It cleans sludge, gum, and varnish. It also removes harmful deposits and dirty oxidized fluid. It improves shifting and reduces transmission heat. The biggest benefit is it extends the life of your transmission making it less likely for an avoidable expense like premature transmission replacement.
