personally, i recommend to flush and/or replace tranny filter FIRST.

if problem still persist, THEN opt to try out lubegard
then you'll know for sure if it really works or not

lol you mentioned you didnt flush hence my recommendation. what about gear box filter though? age of car/tranny?

that said however, if you've flushed 2x in the past and still disappointed in your tranny, then yeah by all means go for it.
for my case i buy/apply lubegard at the workshop near my house, at taman intan baiduri/selayang jaya (near FRIM forest reserve), shop name is torque legend (lol)

quite a nice chap i say. try enquire from him.
