Engine Compatibility
Used in selected automotive and equipment applications where the manufacturer specifies an ATF meeting the performance of GM DEXRON®-III(H), DEXRON®-II, DEXRON®, or Ford MERCON®. It is commonly referenced for older GM and Ford passenger cars and light trucks, and may also be used in certain hydraulic or power steering applications where those fluid types are specified. It is not intended for CVT transmissions or applications requiring Ford Type F fluid.
Serial Number Fitment Notice
Fluid fitment should always be confirmed by the vehicle or equipment owner's manual and the exact transmission specification required for the application. Automatic transmission fluid requirements vary by model year, transmission family, and manufacturer specification.
When This Part Needs Replacement
Replace this fluid during scheduled transmission service intervals, when performing a pan service or fluid exchange, or whenever the existing fluid is degraded, discolored, contaminated, or no longer delivering smooth transmission performance.
Installation Notes
Use only in applications that specifically call for a compatible DEXRON®-III/MERCON®-type fluid. Always verify the required specification before filling, especially on newer transmissions where a different ATF may be required. This fluid should not be used where CVT, Type F, or newer manufacturer-specific ATF formulations are specified.
Alternate/Superseded Part Numbers
Current references identify this item as 550050745. It is also commonly listed simply as Pennzoil Automatic Transmission Fluid 1 qt or Pennzoil Dex/Merc ATF.
Parts Desk Insight
The easy mistake with ATF is assuming all red fluid is the same. This quart is the older Dex/Merc style fluid, so the smart move is to match the exact transmission spec first instead of going by color or bottle shape.
