Anyone use this? I did a filter change and topped off the fluid about 1.5yrs ago but my Jeep still shifts pretty hard. They say you can just add this to your existing fluid, but wouldn't that overfill it?

 

Pay a mechanic to do it right.

 

Depends on how many miles you have on your tranny. When you changed the fluid, did you put the synthetic fluid in it or dex/merc III??? The lucas trans fix is awesome stuff, but I only ever use it on very high mileage trannies (200K+) or ones that slip a little and wouldnt recommend it for a tranny in good shape. And yes, it would overfill it as it adds around a quart of fluid

 

I used dex/merc III. The tranny has about 150k on it right now. Maybe I should do another filter change with a quart of lucas in it.
