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 2012+ Ram 1500 trucks. This thermostat includes adapter sleeves for transmissions with 17mm and 18.5mm unthreaded ports.

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 2012+ Ram 1500 truck 8HP series automatic transmissions with 17mm and 18.5mm unthreaded ports.
  • 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 Racing. Adapter portion is made by us at HPR Tuning.

Not broken yet.

I bought this for my daughter’s tablet and she has put it through the test. It has been dropped multiple times and the tablets still good. It was easy to put on, looks good, and does the job.
