Product Details

• Article Number: 3843H0196P — Ridex Plus premium-tier automatic transmission filter kit for the ZF 8HP 8-speed automatic gearbox. The "P" suffix designates Ridex Plus — the upgraded product line positioned above standard Ridex, featuring enhanced materials and tighter manufacturing tolerances.
• Kit Contents: Automatic transmission oil pan with integrated filter element + replacement pan gasket/seal. The pan-plus-filter is a single unified assembly on the ZF 8HP design — the filter is bonded into the plastic pan and replaced together as one unit.
• Supplementary Info: WITHOUT OIL — transmission fluid is NOT included. You must purchase compatible ZF LifeguardFluid 8 (or equivalent ATF meeting ZF spec) separately. Typically 7–9 litres needed for a full flush and fill on the BMW X3 F25.
• Filter Type: Integrated pan-filter assembly (not a serviceable standalone filter) — the entire plastic oil pan is replaced, bringing a fresh filter, magnetic debris-capture elements, and new pan gasket in one unit.
• Condition: New — factory-sealed in Ridex Plus packaging.
• Manufacturer: RIDEX PLUS — AUTODOC's premium in-house aftermarket line, positioned as the mid-tier upgrade between standard Ridex and true OE brands (Mahle, Febi, ZF). Produced in IATF 16949, ISO 26262, and VDA 6.3 certified factories.
• OEM Cross-References: Alfa Romeo 77367950, Aston Martin FD33-22700-AA, BMW (24 11 5 A12 415 plus additional BMW numbers) — cross-compatible across all manufacturers using the ZF 8HP transmission including BMW, Alfa Romeo, Aston Martin, Audi, Bentley, Chrysler, Dodge, Jaguar, Jeep, Land Rover, Maserati, Ram, and Rolls-Royce.
• Vehicle Compatibility: Designed for BMW X3 F25 sDrive 18d fitted with the ZF 8HP45 or 8HP50 automatic transmission. Also fits an extensive range of BMW F-chassis models (3-Series F30, 5-Series F10, 7-Series F01, X5 F15, X6 F16 and others) and premium-brand vehicles worldwide using the ZF 8HP platform. Always verify against your vehicle's VIN or existing transmission part number before purchasing.
• Service Importance: Although BMW controversially markets the ZF 8HP as "lifetime sealed," ZF itself recommends ATF + filter service every 80,000–100,000 km. Skipping this service is the single biggest cause of premature 8HP transmission failure — worn filter debris, degraded fluid, and collapsed valve body solenoids all trace back to neglected fluid service. Extremely high-value service for any X3 F25 owner with 80,000+ km on the clock.
• Installation Notes: Requires the vehicle at exactly the correct fluid level + temperature (typically 30–50°C) for accurate fill. ZF 8HP fluid level is checked via a standpipe inside the pan — not a dipstick. Best performed by a workshop with the correct diagnostic tool to monitor transmission fluid temperature during fill.
