The fluid named for that transmission
The recommended-fluids table names the fluid. It does not print a fill quantity.
| Item | Figure | Where it comes from |
|---|---|---|
| Six-speed automatic | DEXRON-VI Automatic Transmission Fluid. No capacity is printed. | Recommended fluids and lubricants |
| Eight-speed automatic | DEXRON-HP Automatic Transmission Fluid, GM Part No. 19331925, in Canada 19300537. No capacity is printed. | Recommended fluids and lubricants |
| Transfer case | 1.5 L (1.6 qt). The capacity table prints one transfer-case row for this manual, which also covers 2500 and 3500 series. | Capacities and Specifications |
The recommended-fluids row for the six-speed automatic is DEXRON-VI Automatic Transmission Fluid.
The eight-speed row is DEXRON-HP, GM Part No. 19331925, and in Canada 19300537.
Neither transmission row prints a quart capacity. The transfer-case row does: 1.5 L (1.6 qt), as one figure for the manual.
No transmission fill quantity is printed, so none is added. The transfer-case figure stays labeled as the single capacity in the 2018 Silverado owner's manual.
