Filter
| Brand | Part Number | Markets | Notes | Buy |
|---|---|---|---|---|
| MARELLI | HX193D | 🇲🇽 MX | View on Amazon |
This table covers the replacement filters for this application — the table heading and notes say which circuit. Typical signs include restricted flow — long cranking, weak airflow, or dirty fluid after a short interval. Seat the new filter so it cannot bypass, and use the grade the notes call for.
This group shows a single part: MARELLI HX193D.
Fluid Cooler
| Brand | Part Number | Markets | Notes | Buy |
|---|---|---|---|---|
| DORMAN | 918995 | 🇲🇽 MX | View on Amazon |
This table covers the heat exchangers that cool transmission fluid. Typical signs include fluid that overheats, a leak at the cooler fittings, or milky fluid that says coolant and ATF have mixed. Flush the lines when you replace a cooler. Cross-contamination is how a small leak becomes a transmission job.
This group shows a single part: DORMAN 918995.
Transmission Fluid
| Brand | Part Number | Markets | Notes | Buy |
|---|---|---|---|---|
| AISIN | ATFMFZ | 🇲🇽 MX | 1 Quart | View on Amazon |
This table covers the automatic-transmission fluids specified for this gearbox. Typical signs include harsh or delayed shifts, fluid that smells burnt, or a shudder at light throttle. Use exactly the specification in the notes. Automatic transmissions are unforgiving of the wrong fluid.
