How To Know If You Need A New Trans Filter

Should I Have My Manual Pressure Flushed?

As expected, the industry professionals who provide transmission flushes in their shops are proponents of the service while the not-flushing shops are typically against it. We'll practise our best to sort through the rhetoric and provide you with the information you lot need to make an informed decision.

The debate equally to the effectiveness and safety of a manual flush continues amongst industry professionals. Some manual experts give a thumbs up to flushing while others are completely against it.

Transmission Fluid Affluent (Using Pressure Machine) – The Pros and Cons

The #1 benefit of a fluid flush, versus just a standard fluid/filter alter is that almost all the fluid (ordinarily between 10 and 12 quarts) is flushed from the manual and replaced with clean fresh fluid.

In this process, metal shavings, buildup and debris is also flushed from the transmission, torque converter and oil cooler lines, which is also a expert thing. Make clean ATF insures the transmission is well lubricated and helps keep the tranny absurd.

Is a transmission affluent safe?

Anyone familiar with the subject area of a force per unit area-machine transmission flush has undoubtedly heard stories from automobile owners about how a affluent damaged their transmission or acquired it to neglect not too long after. While some of these stories may be authentic, others are questionable or casual.

As mentioned at the beginning of this knowledge article, a transmission flush tin can be performed by a repair shop using a pressure flush machine or every bit a DIY projection using the manual'due south internal pump to flush the old fluid out and the new fluid in.

In about every instance, when a vehicle owner states that his or her transmission failed shortly later a flush was performed the affluent was done using a loftier-pressure level flush auto at a repair facility. Here'south why:

A manual flush machine uses loftier pressure along with a cleaning agent to flush the old fluid out of the transmission while simultaneously cleaning the internal parts. During this process, the high-pressure cleaning does such a thorough chore that it dislodges dirt and debris that the transmission'southward internal pump is not strong enough to do.

If, while being flushed through the transmission, a slice of droppings becomes lodged in a more crucial are of the transmission it tin crusade problems, even catastrophic transmission failure.Loftier-pressure flushing machines can also blow out internal seals in high-mileage transmissions.

Note: High mileage vehicles that have non routinely had transmission flushes performed are at the greatest hazard of impairment resulting from a high-pressure level affluent.

TIP: For loftier-mileage vehicles that have non routinely been flushed, A DIY affluent using the transmission'due south oil pump or a fluid and filter change is the appropriate service.

Where to take your transmission flushed

Many, only not all, transmission repair shops and automobile dealership service centers offer a transmission fluid affluent service.

Of import – READ Earlier FLUSHING YOUR TRANSMISSION

Earlier flushing your transmission pull the dipstick and look closely at the fluid. If the fluid is dark and has a burnt odor, atransmission flush is not recommended. The recommended service is a fluid and filter alter.

1) Outset the engine and allow it to warm up to normal operating temperature and and so shut information technology off. Place a wheel chock (or wooden block) backside i of the rear tires.

Raise the front end of the vehicle with a floor jack. Position jack stands deeply under the vehicle. Slowly lower the floor jack until the unabridged weight of the vehicle rests on the jack stands. Push on ane corner of the vehicle to check stability of jack stands – the vehicle should not motility.

Or, drive the front of the vehicle onto ramps.

2) Locate the two transmission oil cooler lines. These lines run from the transmission or transaxle to the radiator. One line carries hot ATF from the transmission to the radiator (transmission oil cooler) and the other line carries the cooled fluid back to the transmission.

Disconnect the lower transmission oil libation line where it enters the radiator. Position the drain pan to catch the fluid coming out of the line.

three) From underneath the hood, pull the manual dipstick out of the dipstick/fill tube and insert a long skinny funnel into the fill up tube.

Note: If you do non have a long skinny funnel that will fit into the dipstick tube you can use a short funnel with a small-scale diameter hose or tube extension.

The reason for using a longer funnel or a short funnel with an extension hose is that information technology makes information technology easier to go on the funnel filled with fluid during the flush.

4) Now, remove the caps from 9 quarts of transmission fluid and position the containers in close proximity to the funnel that y'all've inserted into the dipstick tube because one time you start the engine you lot will continuously poor all 9 quarts into the transmission 1 quart immediately after the other. As you are pouring the new fluid into the transmission, the old fluid is beingness pumped out of the transmission into the drain bucket.

5) Start the engine and pour all 9 quarts of fluid into the manual through the funnel trying non to allow the funnel to run dry before get-go to add the adjacent quart. When all 9 quarts have been added, close the engine off.

vi) Reconnect the transmission oil cooler line. At present, support on peak, remove the funnel from the dipstick/fill tube and insert the dipstick. Exist sure the dipstick is pushed all the way downwards into the tube.

7) Now start the engine while the vehicle is still raised and check for leaks. If no leaks are nowadays, close the engine off and so lower the vehicle.

8) With the vehicle sitting on level basis, offset the engine and allow it to warm upward to normal operating temperature. Once warm, depress the restriction pedal and move the shifter through all gears (pausing for a couple of seconds between each shift) before returning the shifter to the Park "P" position.

9) Bank check fluid level. With the engine nevertheless on and at idle, pull the transmission dipstick and bank check the fluid level. If information technology shows full, (or in the full range), wipe the dipstick clean so reinsert it back into the tube. Check fluid level a second time to ostend the reading. If information technology shows full a second time, you are done. If the fluid level is low, add no more than i/3 quart of fluid – then recheck. Repeat this process, calculation less fluid each time, until the dipstick reads full, or in the total range. Do NOT overfill.

Annotation: Virtually automated transmissions practise not have a drain plug. So, if y'all accidently overfill the transmission with fluid, remove ane of the oil cooler lines where it enters the radiator to allow some fluid to drain out. Or, if you have a pocket-size hand pump and a long minor diameter hose y'all tin pump fluid out of the transmission through the dipstick/fill tube.

This concludes the DIY Automatic Transmission Flush Procedures
