Love this site and all the knowledge and humor.I don't think I have posted here for many years but I thought I would make a observation .Have a 1994 saturn sl2 automatic with 220,000 miles. Changed trans. fluid and spin on filter about 15,000 miles ago.Most of you know the saturn seems to develop a "reverse slam" after many miles. Mine never slammed but the delay going into reverse from park was getting longer also shifting from reverse to drive but not as long. I put one half bottle of the Lucus transmission slip/fix in it and it now does not have the delay. I believe it is in the normal shifting time of most automatic transmissions. This is the first Lucus product I have bought.Maybe other aftermarket product would do the same thing but again....just making observation.
