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
- Pans add approximately 2 qts capacity unless otherwise noted.
- Pan part numbers with a + suffix = 4 qts additional capacity
- Pan part numbers with a * suffix = 1 qt additional capacity
