TRANSMISSION
The International Harvester 986 features a sophisticated transmission system with 16 forward and 8 reverse gears, enhanced by a Torque Amplifier (TA) that allows for high/low gear selection on-the-go. This offers improved versatility in varying conditions, though the limitation of shifting ranges only when stationary requires careful planning during operations. With a substantial oil capacity of 90 quarts, ensure optimal maintenance using IH Hy-Tran/B-6 fluid to prevent hydraulic failures and enhance performance longevity.
