Shield Automatic Transmission Fluid Supplement
(ATFS) is a synthetic automatic transmission fluid additive which helps eliminate rough shifting, while lowering heat and slowing down shift time.
Advanced friction modifiers and antiwear additives protect against foaming, rust, gear chatter, and heat.

Directions for use:
Add entire bottle (12 oz.) to automatic transmission, then fill
completely with ChemTech automatic transmission fluid, or add
entire bottle into existing fluid. One bottle treats up to 12 quarts of
automatic transmission fluid.
