It is also responsible for allowing the engine to run at a standstill with the transmission in gear. All modern torque converters also have a lockup clutch. If you think your torque converter clutch has issues, you should connect a scan tool to check if a code, such as P2770, has been stored.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Does the P2770 Code Mean?<\/h2>\n\n\n\n<p>Diagnostic trouble code (DTC) P2770 stands for &ldquo;Torque Converter Clutch Circuit High.&rdquo; The torque converter is composed of an impeller and turbine. The turbine connects to the engine while the impeller connects to the transmission. During normal vehicle operation, the engine spins the turbine, which sends hydraulic fluid to spin the impeller. This process transfers torque from the engine to the transmission without a direct mechanical connection.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/09\/transmission-assembly-with-torque-converter-1024x679.jpg\" alt=\"transmission assembly with torque converter\" class=\"wp-image-73470\" width=\"1024\" height=\"679\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/09\/transmission-assembly-with-torque-converter-1024x679.jpg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/09\/transmission-assembly-with-torque-converter-300x199.jpg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/09\/transmission-assembly-with-torque-converter-768x509.jpg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/09\/transmission-assembly-with-torque-converter-150x99.jpg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2022\/09\/transmission-assembly-with-torque-converter.jpg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>When the TCM detects a problem with the torque converter clutch solenoid or its circuit, it may set code P2770.<\/figcaption><\/figure>\n\n\n\n<p>Once the vehicle reaches a certain speed, the torque converter lockup clutch will engage and mechanically connect the impeller and turbine. This allows the engine to operate more efficiently since there isn&rsquo;t any energy lost from the impeller and turbine rotating at different speeds.<\/p>\n\n\n\n<p>The powertrain control module (PCM) or <a href=\"https:\/\/www.carparts.com\/transmission-control-module\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"transmission control module (TCM)\">transmission control module (TCM)<\/a> operates the torque converter lockup clutch via a solenoid.
