A buddy suggested I reset the TCM, but I\u2019m not a car guy, and I don\u2019t even know what a TCM is. So how do I reset the TCM in a Chevy?<\/p>\n\n\n\n<p><strong>Answer:<\/strong> Resetting the TCM (transmission control module) is usually a great place to start when you\u2019re dealing with transmission trouble in your <a href=\"\/car-insurance\/chevrolet\/\">Chevrolet<\/a>.<\/p>\n\n\n\n<p>The TCM is the brain that connects all the parts of your transmission system. It takes in information from your throttle, engine, transmission fluid sensors, brakes, and more. Then, it uses that information to send signals to the transmission, telling it when to shift gears and creating a smooth driving experience.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"reset-tcm\">3 ways to reset a Chevy transmission control module<\/h2>\n\n\n\n<p>There\u2019s no one sure-fire way to reset the TCM on a Chevy, so you may need to try more than one of these methods to restore your transmission settings.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Start the car and press the gas pedal<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Turn on your car\u2019s ignition.<\/li>\n\n\n\n<li>Let your car idle until the temperature gauge reaches your normal driving temperature.<\/li>\n\n\n\n<li>Switch off your air conditioner, radio, lights, and any other accessories.<\/li>\n\n\n\n<li>Push the accelerator pedal all the way to the floor and hold it there for 15 seconds.<\/li>\n\n\n\n<li>Keep the pedal pressed down and turn off your vehicle.<\/li>\n\n\n\n<li>Lift your foot slowly off of the accelerator pedal.<\/li>\n\n\n\n<li>Wait 2\u20133 minutes, then start the vehicle again.<\/li>\n\n\n\n<li>Let the car run for at least 15 minutes.<\/li>\n<\/ul>\n\n\n\n<div class=\"wp-block-jerry-card\"><div class=\"shadow-variant-card relative overflow-hidden rounded-xl p-8\"><div class=\"flex flex-col gap-3\"><span class=\"text-lg font-medium text-slate-900\">Why do I need to press the accelerator all the way to the floor? <\/span><div class=\"jerry-block-content text-sm text-slate-700\">\n<p>When you press the gas pedal all the way down, it triggers the kickdown switch, which sends a signal to the TCM that the engine needs more power. You must activate this switch if you\u2019re performing a TCM reset using the gas pedal.<\/p>\n<\/div><\/div><\/div><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Turn on the key but don\u2019t start the car<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Turn your key to the \u201cOn\u201d position but don\u2019t start the ignition.<\/li>\n\n\n\n<li>Push the accelerator pedal all the way to the floor and hold it there for 15 seconds.<\/li>\n\n\n\n<li>Turn the key to the off position.<\/li>\n\n\n\n<li>Lift your foot slowly off of the accelerator pedal.<\/li>\n\n\n\n<li>Wait five minutes, then start the car again.<\/li>\n\n\n\n<li>Test drive the vehicle, being sure the transmission shifts through all gears.<\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-jerry-key-takeaway border-primary flex flex-col rounded bg-gray-50 p-6 border-l-4\"><div class=\"flex flex-col md:block md:space-x-1\"><span class=\"has-primary-color text-lg font-semibold\">Note:<\/span><span class=\"text-gray-900 text-base\">In some Chevy models, you may need to remove the key after you turn off the vehicle but before you take your foot off the accelerator pedal.<\/span><\/div><div class=\"jerry-block-content\" contentclassname=\"text-gray-900 text-base\"><\/div><\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\">Disconnect the TCM<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Disconnect your battery, starting with the negative cable first.<\/li>\n\n\n\n<li>Press your horn to get rid of any electrical energy left in your vehicle.<\/li>\n\n\n\n<li>Locate your TCM, then carefully unclip any latches or locks holding the cable in place.<\/li>\n\n\n\n<li>Remove the TCM cable from its port.<\/li>\n\n\n\n<li>Leave the TCM unplugged for about 10\u201330 minutes.<\/li>\n\n\n\n<li>Plug the TCM cable back in.<\/li>\n\n\n\n<li>Reconnect the battery, starting with the positive cable.<\/li>\n\n\n\n<li>Crank your vehicle and drive it for about 15 minutes, being sure to take it through all the gears.<\/li>\n<\/ul>\n\n\n\n<p>Sometimes, disconnecting the battery for around 20 minutes is enough to reset the TCM, even if you don\u2019t unplug the TCM cables.<\/p>\n\n\n\n<div class=\"wp-block-jerry-card\"><div class=\"shadow-variant-card relative overflow-hidden rounded-xl p-8\"><div class=\"flex flex-col gap-3\"><span class=\"text-lg font-medium text-slate-900\">Where is the TCM?<\/span><div class=\"jerry-block-content text-sm text-slate-700\">\n<p>In most Chevys, you\u2019ll find the TCM on the driver\u2019s side of the engine, near the windshield.
