roberbober Posted July 17, 2017 Report Share Posted July 17, 2017 Hello, I have a 2004 SSS and need to replace the rear/front differential fluid along with the t-case fluid. I have searched the threads and there are wonderful how to's but what is the current products you guys are using. I live overseas in Italy so I cant pop down to the dealer to get this information (plus I trust your inputs more anyways). I am going to order it all off of amazon. Thanks in advance guys.

EXGM Posted July 17, 2017 Report Share Posted July 17, 2017 Honestly I would get the GM gear lube for the diffs and GM autotrac for the t-case. The autotrac is special lube and is blue in color.... I am not aware if anyone makes a substitute.... Quote Link to comment Share on other sites More sharing options...
roberbober Posted July 18, 2017 Author Report Share Posted July 18, 2017 I might be a N00b here but my manual for my 05 SSS says Auto Trak II is for Automatic Transfer Case (four-wheel Drive) and to use Dexronn-III Automatic transmission fluid for Transfer Case (All -Wheel Drive) hmmmmmmm I think I am going to go with Mobil 1 synthetic ATF that meets Dexron-III standards. and some Mobil 1 SAE 75W-90 for the reas and 80W-90 for the front. Thanks EXGM for the response... What you think will the Mobil 1 fit the bill? Quote Link to comment Share on other sites More sharing options...
Muggs Posted July 18, 2017 Report Share Posted July 18, 2017 I use Mobil 1 in my diffs and autotrak ll in my trans case for years. Quote Link to comment Share on other sites More sharing options...
