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.

Way too big
Size: XX-Large, Color: Light Gray
Can't really speak to the quality of the suit as it was only tried on, but the look was nice enough. Purchased based on measurements and sizing guide and it was huge. Probably could have gone 2 sizes down but didn't have time to reorder in a different size so just returned. Ordered XXL for son who is 6ft and 220lbs. He wears a large to XL in most tops and a 33x34 in most jeans. Many reviews advised to size up. He was drowning in the XXL. Color was nice light gray.

I sized down
Size: Large, Color: Navy Blue
This suit fit very well! And looks very sharp. It looks great with or without the jacket. I had to size down from my normal large to a medium, but as someone who’s skinny tall, I’ve always wavered between medium and large.

Very pleasantly suprised - good quality, for a great price!
Size: Large, Color: Black
I ordered this suit for my son, for Prom. I was nervous that it was going to be poor quality, or the fit would be really off, but was absolutely blown away by the quality, for the price. ..its a great deal for good quality. Especially for young men. For reference, my son is tall (6'2") and medium/slender build. He usually wears about a 33" waist. I ordered him a Large but maybe could have gone XL. It does seem to be a slimmer fit. He doesn't usually wear XL in anything.
