When to do a flush transmission fluid change?

A transmission fluid flush, however, uses pressure to push all the old transmission fluid out of the system as it is refilled with new fluid. It is more of a fluid exchange than a drain and refill. For this reason, many mechanics recommend performing a second fluid change within 10,000 miles of the first.

What’s the difference between a transmission flush and a drain?

Gravity is simply not enough to remove it because it sits inside other internal parts. A transmission fluid flush, however, uses pressure to push all the old transmission fluid out of the system as it is refilled with new fluid. It is more of a fluid exchange than a drain and refill.

What causes transmission fluid to deteriorate over time?

Like other vital automotive fluids, transmission fluid deteriorates over time. Hard use — such as frequent stop-and-go city driving, hauling heavy loads and trailer towing — will accelerate the deterioration. That kind of driving raises the transmission’s operating temperature, and heat puts more strain on the transmission and the fluid.

Can you change the transmission fluid while sleeping?

Best of luck. Not a good idea to change the tranny fluid on a sleeping transmission. Unless the transmission fluid has been serviced on a regular basis over the years, a sudden shock of new tranny fluid can knock crap loose within the transmission. This ends up in the transmission valve body.

How often should I Change my auto transmission fluid?

Many vehicles will need their auto transmission fluid changed about every 25,000 miles (40,000 km), though some will specify a longer interval. Driving conditions may also require more frequent changing, and checking the fluid regularly will usually show if there has been substantial fluid degradation.

What is a transmission flush?

A transmission flush is a process that clears old fluid from the transmission of a motor vehicle and replaces it with new fluid. This process also helps to remove residue from the converters, coolers and cooler lines.

What happens to transmission fluid when Pan is removed?

With the pan removed, the transmission filter or screen can be replaced. The pan is then reattached using a new pan gasket, and the transmission can be refilled with new automatic transmission fluid. This can be quite a messy process as the fluid drains pretty erratically when the pan is removed.

Where do you flush the transmission coolant line?

Fluid Flush First, you will need to locate the transmission cooler lines where they enter and exit the radiator. It will likely be somewhere close to where your coolant lines run into and out of your radiator. Remove the line that runs out of the transmission and place it into a bucket.

What happens to transmission fluid as it ages?

As the fluid ages, it’s likely to deteriorate and lose its lubricating and cooling capabilities. In addition, it can collect tiny metal shavings from moving parts and gunk that has built up inside the transmission; those could affect shift quality.

How do you remove transmission fluid from a car?

To properly remove all old transmission fluid in an automatic transmission (without flushing the transmission) you have to drain the transmission fluid, refill the transmission fluid, go for a drive, and then drain the transmission fluid again (this process would be done up to three times) to remove all of the old transmission fluid.

How does the transmission pump work in a flush machine?

The input shaft turns the transmission pump and it makes hydraulic pressure. This causes fluid to flow through the cooler line. As fluid leaves the cooler line it enters the chamber on the flush machine. As the old fluid side of the diaphragm fills it pushes the diaphragm up and forces new fresh fluid into the transmission.

What is a transmission flush and why are they necessary?

Is it better to flush a transmission?
