usually the whole bottle goes in , as directions on bottle states run for a few miles, more the better up to 150 mile, drain, replenish with proper fluid or better., most times a fix in a bottle doesn't do it ,though millions sold on high hopes, done it many times myself
Lucas Transmission Fix has a good reputation. Can't say anything about Trans X.
Just don't over fill the trans. Remove a little fluid with a suction gun if the transmission is full.
Drain a quart of transmission fluid and then add the TransX. Follow the directions on the can to the letter! I have seen this stuff work. But if your transmission is in really bad shape, it won't. HTH. -Jim
