No, I hadn't added any oil prior to refilling when I changed it. I poured the friction modifier into the new gear oil before filling. I drove it about 70 miles today, got to a stoplight and had a pretty harsh chatter on take off. Couple miles to my destination, I got to the parking lot expecting some chatter, none. Drove about 35 miles back home and it was perfectly smooth all the way. As of now it seems to be working fine, will find out next time I drive it.
