Ferd/289 Posted February 17, 2003 Share Posted February 17, 2003 Does changing from motor oil to atf in a standard gear box cause the seals to shrink and then leak? 8) Quote Link to comment Share on other sites More sharing options...
80LS1T Posted February 17, 2003 Share Posted February 17, 2003 Ok why do you want to change the recommened fluid to begine with? I know some of the new manual trannies(T56 with the LS1's) use ATF but that is what the factory recommends. I wouldn't change over to ATF unless the manufacture recommends it. There is a reason that they want you to use gear oil and not ATF. Guy Quote Link to comment Share on other sites More sharing options...
Synlubes Posted February 17, 2003 Share Posted February 17, 2003 Guy, Don`t know what trany you have, but maybe try some synthetic gear lube. Quote Link to comment Share on other sites More sharing options...
80LS1T Posted February 18, 2003 Share Posted February 18, 2003 DCarrow, I'm not the one looking to change my oil. Heck I don't even have my motor in yet! Ferd/289 is the one wondering! LOL Yes I would recommend synthenic also though. Guy Quote Link to comment Share on other sites More sharing options...
Ferd/289 Posted February 18, 2003 Author Share Posted February 18, 2003 Yep, just wondering as to what happens if I change to ATF. Synthetic I thought also my have the same effect as leaking seals. Let me know if you have any experience with this. Ferd Quote Link to comment Share on other sites More sharing options...
Synlubes Posted February 18, 2003 Share Posted February 18, 2003 Sorry for the name calling If the seals are in good condition NO LEAKYS. If they are old, maybe. Just depends on how old and hard they are. Quote Link to comment Share on other sites More sharing options...
