If your car is a recent model, you may need to check the transmission fluid level from underneath the vehicle.<\/figcaption><\/figure><\/div>\n\n\n<p>Keep in mind that, nowadays, most cars do not have a transmission dipstick. In many modern cars, you&rsquo;ll need to check the transmission fluid level from underneath the vehicle. What&rsquo;s more, some newer cars require a scan tool to check the transmission fluid level. And some vehicles have their transmissions sealed, so there&rsquo;s no way to check or service the fluid. <\/p>\n\n\n\n<p>For these reasons, it&rsquo;s important to check your owner&rsquo;s manual before attempting to check or service your transmission fluid. <\/p>\n\n\n\n<p>Also, even if your car has a dipstick, it&rsquo;s a good idea to consult the owner&rsquo;s manual before checking the ATF, as there are often discrepancies in the fluid-checking process. The steps we&rsquo;ve listed above are only a general guide. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Change Transmission Fluid (in Cars With Automatic Transmissions)<\/h2>\n\n\n\n<p>As was mentioned earlier, these days you&rsquo;ll find that there are different types of automatic transmission designs. So before attempting to service your transmission, you should consult a repair manual to determine the correct procedure. <\/p>\n\n\n\n<p>The following generic outline is for a transmission that has both a dipstick and a removable pan. <\/p>\n\n\n\n<p>Also, you should only need the most basic shop tools to change your automatic transmission fluid. These tools include: <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Correct automatic transmission fluid<\/li>\n\n\n\n<li>New <a href=\"https:\/\/www.carparts.com\/blog\/bad-transmission-filter-symptoms-plus-faq\/#How_Does_a_Transmission_Filter_Work\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"transmission filter\">transmission filter<\/a> and gasket (AKA transmission filter kit)<\/li>\n\n\n\n<li>Jack and jack stands <\/li>\n\n\n\n<li>Socket set and ratchet <\/li>\n\n\n\n<li>Solvent<\/li>\n\n\n\n<li>Longneck funnel<\/li>\n\n\n\n<li>Clean rags<\/li>\n\n\n\n<li>A two-gallon container or catch pan<\/li>\n\n\n\n<li>Tarps, cardboards, or newspapers<\/li>\n\n\n\n<li>Torque wrench<\/li>\n<\/ul>\n\n\n\n<p>Once you have gathered all the necessary tools, you can move forward with changing your transmission fluid. Here&rsquo;s how it&rsquo;s done: <\/p>\n\n\n\n<p>1. Make sure that the vehicle has been sitting long enough that the engine and transmission are cool. Hot transmission fluid can cause severe personal injury.<\/p>\n\n\n\n<p>2. Safely raise and support the vehicle using a jack and jack stands. Set the parking brake and chock the rear wheels. <\/p>\n\n\n\n<p>3. Set the two-gallon container or catch pan on a piece of tarp or some newspapers and position it under the transmission pan.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"614\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/how-to-remove-transmission-pan-1024x614.jpg\" alt=\"removing transmission pan bolts\" class=\"wp-image-9867\" style=\"width:1024px;height:614px\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/how-to-remove-transmission-pan-1024x614.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/how-to-remove-transmission-pan-300x180.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/how-to-remove-transmission-pan-768x461.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/how-to-remove-transmission-pan.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">Remove all but a few of the transmission pan&rsquo;s bolts, angling the end with the bolts removed downward to dump transmission fluid into a container.<\/figcaption><\/figure>\n\n\n\n<p>Loosen the bolts of the transmission pan to allow the fluid to drain.

But to find out the correct service interval for your car, make sure to check the maintenance schedule outlined in the owner&rsquo;s manual.<\/p>\n\n\n\n<p>The service interval may be shorter for some vehicles and longer for others. Some vehicles may not even require the transmission fluid to be changed because the transmission is sealed. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/trailer-towing-1024x683.jpeg\" alt=\"pickup truck towing a trailer\" class=\"wp-image-9584\" style=\"width:1024px;height:683px\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/trailer-towing-1024x683.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/trailer-towing-300x200.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/trailer-towing-768x512.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/trailer-towing-600x400.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2020\/05\/trailer-towing.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption class=\"wp-element-caption\">Trailer towing can cause your transmission fluid to deteriorate quickly.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">How Does Transmission Fluid Deteriorate?<\/h2>\n\n\n\n<p>Most transmission fluids simply break down over time. There are, however, certain conditions that can cause ATF to deteriorate more quickly than usual. <\/p>\n\n\n\n<p>For example, hauling heavy loads, trailer towing, and frequent stop-and-go driving can cause the transmission to run hot, thereby causing the fluid to degrade quickly. Transmission problems can also cause the fluid to overheat and break down.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Signs of Bad Transmission Oil<\/h2>\n\n\n\n<p>If your vehicle starts to show these symptoms, it might be time to replace your transmission oil even if it hasn&rsquo;t yet reached the end of its typical lifespan:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Transmission fluid maintenance indicator alerts<\/li>\n\n\n\n<li>An illuminated check engine light<\/li>\n\n\n\n<li>Dark brown or black transmission fluid condition<\/li>\n\n\n\n<li>Metal flecks or moisture in the oil<\/li>\n\n\n\n<li>Burnt fluid<\/li>\n\n\n\n<li>Slipping gears<\/li>\n\n\n\n<li>Delayed or rough shifting<\/li>\n\n\n\n<li>Unusual noises<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Why Is Transmission Oil Important?<\/h2>\n\n\n\n<p>Knowing how to change transmission oil is important because the fluid serves multiple purposes in your vehicle. Transmission fluid lubricates the transmission&rsquo;s moving parts, cools the system, and dissipates the heat produced during operation. This prevents overheating and reduces wear and friction on the transmission&rsquo;s components.<\/p>\n\n\n\n<p>Transmission fluid also serves as a seal that prevents leaks and maintains the proper pressure levels in the system to ensure effective operation. It helps make shifting smoother and cleans and protects the transmission components from contaminants and debris.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where to Get Automatic Transmission Fluid for Your Vehicle<\/h2>\n\n\n\n<p>Oil, including automatic transmission fluid, is the lifeblood of any vehicle.
