Im having trouble getting it in gear..takes around a minute or so when cold...but once its warm its fine. anyways some advised me a filter/fluid change would be a good idea. I got a filter an dwas wondering if that high mileage trans fluid is good for me..what about the lucas stuff? any other additives that i should add? how does this stuff work? Do I fill my trans all the up with trans fluid then add the lucas stuff? Do i use just one bottle of the lucas(or otherbrand) stuff?
