Bolt on deep transmission pans are made from cast aluminum and designed with cooling fins to dissipate heat quicker. Cast aluminum pans hold approximately 2 to 4 extra quarts of fluid, thereby reducing operating temperatures and increasing transmission life.
These pans also increase transmission case rigidity, allowing more torsional twist capacity. (A must for 4X4 units.)
All necessary hardware is included
(including filter extensions).
No modifications are necessary
Increased fluid capacity by approximately
2-4 quarts depending on application.
