[00:00:30] I am Larry Kosilla, pro-detailer and coach for the final 15 years, however in the case of what’s beneath the hood, I am the scholar. Comply with me as specialists educate me the right way to diagnose, repair, and modify automobiles on Autoblog’s Wrenched. I’ve heard of fast lube locations providing a transmission change, a service, and even a flush. What is the distinction between these two? – Nicely, a fluid change could be the place you simply drop the fluid out, you place recent fluid on high. A service could be eradicating the pan,
[00:01:00] placing in a recent filter, after which filling the fluid again within the high. A flush truly cleans the fluid out of the torque converter, which maintain just a few quarts of oil that you would be able to’t drain by simply taking the pan out, so one of many higher methods to do it’s should you put in recent fluid, put in a brand new filter, drive it round for awhile, you are dissipating loads of the previous fluid, mixing it in, then you definately drop that once more. Now it is arduous as a result of it’s important to do it twice, nevertheless it’s really easy you’ll be able to truly do it your self. – [Larry] Examine the present fluid to get an thought of its situation, odor, shade, and stage.
[00:01:30] Use the identical shade paper towel now as you’ll later so you’ll be able to evaluate the transmission fluids simply. Make sure you have an empty catch can earlier than you begin this course of. With the automotive within the air, discover the transmission and unscrew the drain plug or, in some instances, you will have to unscrew just a few bolts on the pan and do what’s known as a sluggish drain earlier than eradicating all of them to keep away from an enormous mess. Fortunately, this automotive has a drain plug, which makes this course of quite a bit simpler.
[00:02:00] Now, with many of the fluid out, take away the transmission pan. With the pan out of the automotive, now it is time to do some detailing. First, take away the earlier gasket with a plastic razor blade or scrub pad, ensuring to not gouge the flat floor, which could trigger a future leak. Brake clear the pan inside and outside, associated bolts and pay particular consideration to the magnet filter. Very like oil drain plugs, transmissions have magnets, as properly, hooked up to the within of the pan
[00:02:30] to draw steel shavings from the transmission throughout its use. It is scary to see all of the steel items, however I am instructed it is utterly regular. Have a look at the transmission mating floor and ensure that is as clear because the pan. That is a particularly essential step for an ideal seal, so it should not really feel tough or bumpy, or have any leftover gasket residue. Now that every little thing is clear and able to go, it is time to substitute the filter, nevertheless it’s a good suggestion to ensure the previous one and the brand new one are precisely the identical.
[00:03:00] Most filters may have a rubber gasket, like this one right here. Add new transmission fluid to the rubber for a greater seal previous to putting in and torquing. Subsequent, reinstall the pan, however a brand new gasket is required to exchange the previous one we scraped off. Earlier than including a brand new gasket, a sticky gasket adhesive is positioned on the mating floor to carry the gasket in place throughout the re-installation to keep away from it transferring or sliding and presumably inflicting a leak down the street. Now rigorously set up the pan whereas making an attempt to keep away from transferring the gasket,
[00:03:30] then hand tighten all of the freshly cleaned bolts. As soon as the pan bolts are hand cosy, torque them in a criss-cross sample to evenly crush the gasket, a lot the identical as torquing your lug nuts. On this case, it is only a few extra bolts. When you’re questioning the place to search out the torque specs in your automotive, you’ll be able to simply verify on-line or together with your native vendor. Take the previous fluid in your beforehand empty catch can and pour it into an previous gallon or quart container to measure precisely how a lot was faraway from the tranny.
[00:04:00] Make sure you correctly get rid of the spent fluid. That is poisonous and have to be disposed of correctly. Examine your native auto elements retailer to see in the event that they recycle or can advocate the place to go. Add your funnel to the dipstick tube, and substitute the identical quantity of previous fluid, however with new fluid. Subsequent, begin the automotive, and together with your foot on the brake, undergo the gears to assist flush the clear fluid by means of the torque converter, which can squeeze out the previous fluid that was as soon as trapped and left behind even after our first drain.
[00:04:30] Now with the automotive turned off, return to the drain plug and drain the fluid as soon as once more with out eradicating the pan. You will see the clear fluid we put in only a few minutes in the past blended with the previous, and now has turned every little thing a bit bit darker, nevertheless it’s positively higher than our previous or unique fluid we as soon as had within the automotive. Now repeat the final step by including the identical quantity that was eliminated like we did earlier than. Afterwards, begin the automotive, run by means of the gears once more,
[00:05:00] and high off the fluid as required. Most automobiles have to be working in idle for the dipstick studying to be correct, however verify your handbook to make sure. Likewise, be sure that your automotive is on a flat and even floor to keep away from a false dipstick measurement. So here is what I’ve realized. When altering your fluid, you actually solely get about 50% of the previous fluid out as a result of the remainder is trapped within the intricate maze that’s your transmission. Quantity two, be sure you use the precise spec fluid in your transmission present in your handbook
[00:05:30] or you might trigger untimely carrying. Quantity three, having a drain plug is critical to finish our compromise between a easy change and our DIY flush as we did on this video. And lastly, should you resolve to go to knowledgeable, perceive the distinction between a change and a flush. Be sure your mechanic is conscious that you recognize the distinction between the 2 providers, what number of quarts your tranny holds, if he is altering the filter, and naturally, if that is included within the worth.
