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.

poli glow shine
its works great .when applying more coats the shinier it gets i used on several old boats because the florida sun bakes the jell coat right off and no wax made can withstand salty seas , so why not ,, when you apply use the mit and don't gob it on .. nice and easy and recoat in five minutes when you get to about five coats you will be amazed.looks like new .. just a tip also after about a year or so and you want to re apply,, go to your local hardware store and get a gallon of high strength or non diluted floor stripper and put in spray bottle and use to remove old poli-glow also great for cleaning stubborn stains [ i use full strength ] just spray on and brush with a scrub brush and rinse ..and let dry and re apply ,, its also works on car faded bumpers ,, also never use harsh cleaners it will cause streaking the best thing i have found for cleaning the boat after poli glow was put on is car wash from auto store with wax or not it seems not to hurt the shine . it reminds me of mop an glow,,.

Poli Glow used on bottom portion of the picture
Just put it on 21 foot RV, was impressed with the shine. Key is to make sure the applicator is moist. I periodically dampen with water. Realizing it wasn't going to revive the stickers. Question is How long it will last? What will it look like after it rains? Pictures attached, bottom portion was done with poli glow on June 7,2026 and I have just under a half of bottle left. Maybe I will update once it rains or how long the shine last.
