It seems that additives in the trans or engine seem to get picked on around here so I thought I would ask what additives have worked for you guys.
I have never used a engine oil additive but I have used some stuff in a transmission with instant results.

I used this in a 1994 Crown Vic with 200K+ on the original trans. The car had a torque converter shudder that would knock your teeth loose. I poured in the pint bottle and the shudder stopped within 1/4 mile of driving and stayed gone for 10K miles at a time. The original trans was working fine when I sold the car with 270K.
You guys have any success stories with additives?
