8HP DODGE Challenger/Charger Thermostatic transmission cooler adapter

HPR Tuning has partnered with the American company Improved Racing to create the first bolt-on transmission fluid adapter with a thermostat for the 8HP transmissions found in the Dodge Challenger and Charger.

The adapter's built-in thermostat automatically bypasses the transmission cooler until the fluid reaches 160ºF. The thermostat reduces rough shifts caused by overcooled transmission fluid, reduces wear, and improves efficiency and horsepower. The transmission can now reach operating temps quickly with large aftermarket transmission coolers. This allows for high cooling capacity without sacrificing drivability.

The adapter features -8AN male connections for aftermarket AN lines.

Important Application Notes:

• The adapter can only be used in conjunction with external transmission fluid coolers.
• The adapter does not directly connect to the factory lines. Aftermarket AN lines must be used.
• The adapter will only help resolve rough shifting issues if they are caused by overcooling of the transmission, usually due to the addition of a larger aftermarket transmission cooler.

Features and Benefits

• Bolt-on fitment for 2015-2023 Dodge Challenger and Charger 8HP series automatic transmissions.
• Built-in thermostat prevents temperatures from dropping below optimal levels, reducing wear, improving efficiency and horsepower, and helping to eliminate rough shifting.
• -8AN male connections.
• 6061-T6 billet aluminum construction with black MIL-A-8625 Type II anodized finish.
• Thermostat portion is made in the USA by Improved. Adapter portion is made by us here in Norway.
