LUBEGARD® Highly Friction Modified (HFM) Automatic Transmission Supplement is a dual-purpose problem solver that corrects friction modification problems and enhances base ATFs to perform like highly friction modified OEM ATFs. Supplement your current ATF with HFM to prevent and eliminate torque converter lock-up shudder, soften and modify harsh shifts, and extend the life of the ATF. LUBEGARD® Highly Friction Modified (HFM) Automatic Transmission Supplement contains a concentrated additive package with additional friction modifiers that can be safely added to any ATF (except CVT, DCT, and Ford Type F [1986 and earlier models]) including full synthetic, semi-synthetic, and conventional fluids to eliminate severe torque converter lock-up shudder and soften harsh shifts.
