The ATS Diesel 6R140 Pan is the best aftermarket transmission pan on the market for your Late-Model Ford Diesel Pickup. There are several ingenuitive designs that are incorporated into this newly designed 6R140 Deep Pan. To begin, ATS Diesel has radically redesigned the fluid flow dynamics in the pan by adding a flow dam that keeps fluid available to the pickup tube under heavy acceleration or driving on a steep grade. The pan also features a true tapered design, making the drain plug the lowest point of the pan. This will allow for easier, more complete draining!
