Chrysler ATF +4 Type Trans Fluid 1Qt

The Chrysler ATF +4 Type Trans Fluid 1Qt by AMALIE is the OEM-specification transmission fluid engineered specifically for Chrysler, Dodge, and Jeep automatic transmissions requiring ATF +4 certification. Whether you're performing routine fluid maintenance, topping off between services, or rebuilding a transmission, this quart bottle provides the exact formulation your vehicle's gearbox demands for optimal shift quality, torque converter lockup performance, and hydraulic pressure stability. ATF +4 is not interchangeable with older ATF or competing specifications—using the correct fluid protects your transmission's internal clutches, seals, and valve body from premature wear and shift lag.

AMALIE's formulation delivers advanced friction modifiers and anti-wear additives that maintain consistent viscosity across the full operating temperature range, from cold start to sustained highway driving. The fluid's low volatility prevents varnish buildup in the transmission cooler and lines, extending service intervals and reducing deposit formation on clutch plates. ATF +4 also provides superior oxidation stability and thermal shear resistance compared to earlier generation fluids, which means your transmission stays cooler and maintains proper pressure modulation through the valve body under load. The 1-quart size makes it ideal for top-ups without requiring a full drain-and-fill procedure, though professionals often use multiple quarts during routine maintenance.

This product is essential for 1998-and-later Chrysler-platform vehicles, including A604, A606, 45RFE, 545RFE, 65RFE, and NAG1 transmissions that explicitly require ATF +4. Mechanics and DIY builders know that skipping the correct fluid specification leads to shift flare, harsh engagements, and eventual internal damage—particularly in modified or performance builds where transmission temperature climbs higher than stock. AMALIE's reputation for consistent quality and OEM approval makes this 1-quart bottle a reliable choice for both emergency top-ups on the road and planned maintenance in the shop.
