Keep in mind when i drained my transmission the old fluid smelled like it was at the end of its life and i have no idea which fluid was in it before as I’ve only put about 15k miles on the car in over a year and a half. Overall I’m very happy with this fluid and it seemed to make shifting overall more smooth. Would recommend Review: Feel good - I used this stuff to replace the old gear oil for my DC2 Integra ITR. No issues as if now. Shifts pretty good. ## Features - The information below is per-pack only - HIGH PERFORMANCE - gear protection and longer synchro life. Recommended for GL-1, GL-3, and GL-4 applications. - QUICKER SHIFTS - perfect synchronizer coefficient of friction and eliminates notchy shifting, even when cold - REQUIREMENTS - gear oil viscosity of 75W; 80W; SAE 40 10W40 and 15W40 motor oil - POPULAR GEAR OIL FOR - GL-1, GL-3 and GL-4 applications, as well as where most special synchromesh fluids are specified.
