twiztidss Posted October 4, 2014 Report Share Posted October 4, 2014 Can anyone steer me in the direction of this? I have a 2003 silverado ss so it has the awd transfer case. I did all the fluids a couple years ago and would like to do them again. Front and rear diff - 75w90 (couldn't remember 2-4 quarts?) Transmission- universal ATF? How much? I used the bg stuff last time AWD transfer case- for the life of me I can't find what type is needed. I thought i used royal purple synchromax last time. 2 quarts? I want to have everything ready to go so I can do it all the same day. Thanks for info in advance 1 Quote Link to comment Share on other sites More sharing options...

Red Pyrate Posted September 7, 2021 Report Share Posted September 7, 2021 (edited) Need front transfer case fluid changed on my 04 SS. 185K, changing out everything re no idea of previous owner maintenance. First time messing with a front transaxle. I gather need 2 quarts of ACdelco Auto Trak II for the front transfer case, What and where and how do I do differential gear oil? New territory for me.
