DSM Planetary Gear Set for F4A33/W4A33

DSM Automatic Transmission Straight Cut Planetary Gear Set.

These are stronger than OEM material, a thicker tooth profile for reduced bending stress, and approximately 5% more effective gear width at the lower planets by optimizing thrust washers. These are an improvement from OEM parts but not indestructible. They require good lubriction oil pressure feed (minimum 55psi) and high quality oil with extreme pressure additives. Documents linked below for more details.

Set Includes: 3x short planet gears, 3x tall planet gears, 3x rivets, 1x short sun gear, 1x tall sun gear, 1x ring gear
