after i change my transmission fluid would it be a bad/good idea to add somethign liek lucas or any other product (if so please name them) to stop rough gear changing. my tranny doesnt jump crazy, ive seen alot worst, but when switching to higher gears mostly you can fell a small jerk.

 

I had normall used Lucas fuel injector cleaner, when I saw their transmission additive... My 1-2 shifting was rough when it was cold, so I added some to my trannsmission fluid and now it shifts more smoothly.. Try it.. unless someone else tells you not to for whatever reason.

 

what about those Lucas products... how effective are they?
(I know I don't need anything on my Max... but any other junkers I gotta service in the future, e.g. my dad's mazda... it'd be nice to know if Lucas oil products are worth suggesting)
