F4A51-2 Transmission Filter Kit for 1997-1999 Mitsubishi & Hyundai

F4A51-2 Automatic Transmission Filter Kit — 1997–1999 | Fits Mitsubishi & Hyundai

This transmission filter kit is engineered for the F4A51-2 4-speed automatic transmission used in 1997–1999 Mitsubishi and compatible Hyundai vehicles. The kit bundles the two components most critical to a successful transmission service: an internal filter for the F4A51/F5A51 (1996–April 1999 build date) and a nitrile rubber side pan gasket for the F4A41/F4A42/W4A42.

What's Included:

• 1x F4A51/F5A51 Internal Transmission Filter (fits 1996–April 1999 production)
• 1x F4A41/F4A42/W4A42 Side Pan Gasket (Nitrile)

Why Replace Your Transmission Filter? Over time, fine metal particles, clutch material, and fluid breakdown byproducts accumulate in the transmission pan and saturate the internal filter. A restricted filter reduces hydraulic pressure and limits fluid flow to the valve body, which can cause delayed or harsh gear engagement, erratic shifting, slipping between gears, transmission overheating, and premature wear on clutch packs and planetary gearsets. Servicing the filter and pan gasket at the recommended interval helps restore proper hydraulic function and can extend overall transmission life significantly.
