Product description

*** DODGE kits will not use the pressure gauge add on as you will not be able to read pressure if not in gear. *** 

Our kits are made with stainless braided high pressure hose and fittings that match the OEM connections. This allows for easier installation and quick removal should the need arise. There is no cutting or modifying needed of the OEM lines or connections when installing our unit.

Automatic transmissions have internal filters designed to capture only large particles. These filters are designed as a pickup to keep large particles from flowing through the transmission. These filters are on the suction side of the pump. Fine filtration in the pan is not an option for the transmission manufacturers due to the fact that transmission pumps should not be restricted. The only way to get fine filtration for a transmission is with an external transmission filter kit on the push side of the pump. The Allison in the Chevy and many medium duty and heavy duty trucks come equipped from the factory with an external transmission filter. This is not a new idea in transmission maintenance and protection. 

The OEM filter location requires that you pull the pan to change or check the filter. With our kit you can simply spin on a new filter element. With the optional pressure gauge to monitor when you should change your filter, you can avoid unnecessary filter changes.

How it works:  Our filter is on the "push" side of the pump.  This location allows for a filter with increased efficiency, or a smaller micron rating. Normally you have the dirty fluid in the pan, then hopefully the OEM filter catches the really big particles before it enters the valves and pump. After running through the transmission the fluid will have picked up clutch dust and other impurities which are all normal in any automatic transmission. This dirty fluid would be recirculated back to the pan, but with our kit you can catch dirty fluid BEFORE it makes it back to the pan. Keeping the fluid clean, thus keeping your valve body clean which keeps your transmission shift at its highest quality. After installation of our external kit the filter in the pan now acts simply as a pickup for the pump and will never need changed.

Our unit has an internal bypass valve in the housing as an added safety feature. This bypass valve is set at 25 psi to allow some fluid to bypass the filter if it were to get too dirty and restrict flow. In addition, if the filter becomes plugged, our unit will go into complete bypass mode and allow the full volume of fluid flow to bypass the filter and insure that your transmission always has returning fluid for lubrication.   With routine oil and filter changes and a properly operating transmission this full bypass mode should never occur.

Our filters have a micron rating of 22 microns. That is plenty for any transmission. Pan filters have no real micron rating. Many are nothing but screens.

Our kit also acts as a "mini" cooler since it is detached from the transmission and the air flow over the filter element would help to dissipate a small amount of heat.


Protects your transmission in the case of a torque converter failure by catching the debris before it can make it back to the transmission. Before the installation of our Factory Tech Monsterbox, we personally lost 3 torque converters in one transmission and the transmission was still in perfect condition.

No need to drop the pan again for messy filter changes. Your OEM filter will only require changing every 100,000 miles or so.

The fluid in pan stays clean, protecting the transmission from debris.

  • The filter canister acts as a small transmission cooler.
  • The bypass valve design allows fluid flow even if the filter plugs with debris.

  • Allows the addition of a transmission filter pressure gauge to monitor the condition of the filter.
  • Allows the addition of the transmission flush valve to make torque converter purging easier.
  • The spin on filter replacements are less expensive than the OEM style.
