Purpose and Specifications

RAVENOL STF 1L is a fully synthetic synchromesh transmission fluid designed for manual transmissions and transfer cases in GM and Chrysler vehicles. It meets key specs like Chrysler MS-9224 and Chrysler MS-9417, delivering smooth gear shifts and maximum wear protection even under high loads and temperatures up to 150°C.

This 1-liter oil creates a tough lubricating film that stays stable in extreme heat, reduces friction for easier shifting, and protects gears, bearings, and synchronizers during demanding drives like track days or heavy towing. Its advanced additives prevent foaming at high speeds and ensure reliable performance from cold starts down to -40°C.

When to Use / Replace?

Use RAVENOL STF in compatible transmissions such as Chrysler NSG370 (Jeep Liberty 2005-2008, Wrangler 2005+), New Venture Gear NV T350/T3550, and Tremec T5/T56. Ideal for vehicles needing precise syncro action without hypoid or limited-slip axles.

• Replace every 60,000-100,000 km or 3-5 years under normal driving; sooner (every 30,000 km) for severe use like racing or towing.
• Check fluid level and condition every 20,000 km or 12 months.
• Shelf life: 5 years unopened in cool, dry storage.
