My transmission was slipping just a little bit between 2nd and 3rd gear it would cause it to rev just for a second between second and third I put transfix by Lucas in it and I was 7 miles from my house by the time I got home it would barely go and it would slip out of second and third gear all the time I don't think the bands wore out that quickly so I figured it has to do something with putting the transfix in it since then I replaced the transmission fluid and it still doing the same thing
