# Mishimoto 12-19 Dodge V6 8HP Thermal Bypass Valve Kit FF The transmission in your 2012-2023 Dodge Charger, Challenger, or Chrysler 300 is the heart of its drivetrain. Whether you're hauling groceries or knocking out highway miles, it's vital to keep it performing at its best, and keeping the transmission fluid cool is crucial to that goal. In an attempt to balance drivability and the health of your transmission, Dodge/Chrysler fitted a thermostatic bypass valve to the lines that feed the transmission cooler. This valve ensures fluid doesn't flow through the cooler before the transmission reaches operating temperature, preventing overcooling in cold environments. However, when the thermostat in this valve fails, it's almost a guarantee your transmission will overheat. Moreover, those who live in hot climates will likely never have to worry about overcooling, rendering the valve a useless flow restriction. That's why Mishimoto has developed a full-flow thermostatic bypass valve for the 2012-2023 Dodge Charger, Challenger, or Chrysler 300. The Mishimoto thermal bypass valve kit includes an all-aluminum CNC-machined housing that replaces the stock unit. This full-flow valve allows fluid to pump through the cooler as soon as the vehicle is started, eliminating the potential failure point of the stock bypass and providing cooling benefits. The full-flow design is beneficial to vehicles operating in hot climates, extreme driving conditions, or towing heavy loads. As with Mishimoto products, this Full-Flow Transmission Thermal Bypass Valve Kit includes our signature Lifetime Warranty. - Direct-fit for 2012-2023 Dodge Charger/Challenger, Chrysler 300 w/8HP45 or 845RE transmission - Eliminates failure-prone bypass valve - Installs in less than 1 hour This Part Fits: Year Make Model Submodel 2012-2014 Chrysler 300 Base 2012-2020 Chrysler 300 C 2012-2014 Chrysler 300 C Luxury 2015-2017 Chrysler 300 C Platinum 2012,2015-2020 Chrysler 300 Limited 2012-2021 Chrysler 300 S 2012-2014 Chrysler 300 SRT8 2013 Chrysler 300 SRT8 Core 2018-2021 Chrysler 300 Touring 2018-2021 Chrysler 300 Touring L 2016 Dodge Challenger 392 Hemi Scat Pack Shaker 2017-2021 Dodge Challenger GT 2012-2021 Dodge Challenger R/T 2017-2019 Dodge Challenger R/T 392 2012 Dodge Challenger R/T Classic 2015-2016 Dodge Challenger R/T Plus 2016 Dodge Challenger R/T Plus Shaker 2016-2021 Dodge Challenger R/T Scat Pack 2021 Dodge Challenger R/T Scat Pack Shaker Widebody 2019-2021 Dodge Challenger R/T Scat Pack Widebody 2016 Dodge Challenger R/T Shaker 2014 Dodge Challenger Rallye Redline 2015 Dodge Challenger Scat Pack 2015-2018 Dodge Challenger SRT 392 2018 Dodge Challenger SRT Demon 2015-2021 Dodge Challenger SRT Hellcat 2019-2021 Dodge Challenger SRT Hellcat Redeye 2019-2021 Dodge Challenger SRT Hellcat Redeye Widebody 2018-2021 Dodge Challenger SRT Hellcat Widebody 2020-2021 Dodge Challenger SRT Super Stock 2012-2014 Dodge Challenger SRT8 2012-2021 Dodge Challenger SXT 2012,2015-2018 Dodge Challenger SXT Plus 2017-2018 Dodge Challenger T/A 2017-2018 Dodge Challenger T/A 392 2021 Dodge Challenger T/A 392 Widebody 2017-2018 Dodge Charger Daytona 2017-2018 Dodge Charger Daytona 392 2018-2021 Dodge Charger GT 2018 Dodge Charger GT Plus 2012-2021 Dodge Charger Pursuit 2012-2021 Dodge Charger R/T 2017-2018 Dodge Charger R/T 392 2015-2016 Dodge Charger R/T Road & Track 2015-2018 Dodge Charger R/T Scat Pack 2019-2021 Dodge Charger Scat Pack 2020 Dodge Charger Scat Pack 392 Widebody 2012-2017 Dodge Charger SE 2015-2018 Dodge Charger SRT 392 2015-2020 Dodge Charger SRT Hellcat 2021 Dodge Charger SRT Hellcat Redeye Widebody 2020-2021 Dodge Charger SRT Hellcat Widebody 2012-2014 Dodge Charger SRT8 2012-2021 Dodge Charger SXT 2012,2018 Dodge Charger SXT Plus 2018 Dodge Charger SXT Plus Leather 2021-2024 Ram 1500 TRX 2021 Ram 1500 TRX Launch Edition ## Details - **Price:** 160.65 CAD - **Vendor:** Mishimoto - **Type:** Transmission Coolers ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 160.65 CAD | In stock | ## Images - Photo - Primary - User 1 - User 2 - Logo Image --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/mishimoto-12-19-dodge-v6-8hp-thermal-bypass-valve-kit-ff) > Updated: 2026-06-27
