The Passenger Vehicle Automatic Transmission Fluid Anti-Shudder Friction Tester is a specialized friction testing system designed to evaluate the friction characteristics and anti-shudder durability of automatic transmission fluids (ATF) under controlled pressure, speed, and temperature conditions.

You can use this tester to accurately simulate the real operating conditions of wet friction pairs in automatic transmissions, enabling quantitative analysis of friction behavior during running-in, low-speed operation, and long-term durability. It provides reliable technical support for lubricant development, quality control, and compliance verification.

Standards

The tester is designed to meet and support the following domestic and international standards and test methods:

(1) GB/T 11118 — Tribological Performance Test Methods for Lubricants

(2) GB/T 3142 — General Test Methods for Lubricant Viscosity and Performance

(3) JASO M348 — Friction Characteristics Test Method for Automatic Transmission Fluids

(4) SAE No.2 — Friction Test Method for Automatic Transmission Fluids

Note: Differences in speed profiles, loading modes, temperature programs, and data processing requirements among standards can be accommodated through software parameter configuration.
