LUMINATOR Posted April 12, 2013 Report Share Posted April 12, 2013 I have a 1990 Chevy Lumina with the 3.1, automatic. The car has been shifting hard into overdrive and I've been thinking about doing a fluid and filter change on it. The car has 102,000 miles on it, Not sure if I should change it or not Also has anyone used the products Trans tune from sea foam or Lucas oil transmission fix in any of there transmission do these products work?

RobertISaar Posted April 12, 2013 Report Share Posted April 12, 2013 don't stick anything other than dex2/dex3 or dex6 trans fluid in your transmission. everything else is a crapshoot as to whether it will fix an issue or cause immediate and total failure. do yourself a favor and change out the filter/fluid now, rather than when it's an obvious issue.

LUMINATOR Posted April 12, 2013 Author Report Share Posted April 12, 2013 Thanks for getting back to me RobertlSaar! I checked the transmission fluid today after driving it for a while. It was full but I saw some bubbles on the dip stick, is that a bad sign? Ok I will stay away from the transmission additives, and yes I think I will plan on doing a filter and fluid change here soon!

19Cutlass94 Posted April 12, 2013 Report Share Posted April 12, 2013 If you can afford it, use dex6. That stuff is miles ahead of dex3. Sent from my iPhone in some random spot of Texas. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted April 12, 2013 Report Share Posted April 12, 2013 small amounts of bubbling isn't that abnormal... it's if the filter sucks up air bubbles(meaning lots of bubbles/foaming) is where there will be problems. Quote Link to comment Share on other sites More sharing options...
LUMINATOR Posted April 12, 2013 Author Report Share Posted April 12, 2013 So is the dex6 a lot better fluid than the dex3? And would it be fine to use it in a 1990 Chevy Lumina with a 3.1 in it? Quote Link to comment Share on other sites More sharing options...
