09 RDM and TC advice

[austinyoung89]

Hey guys,

I'm about to do the maintaince and change my Rear Differintal Fluid and Transfer Case fluid on my 09 LT AWD Equinox. According to my manual both the part numbers for the fluids have been disscontinued. Anyone know what I need for TC and can I use any 75w-90 in the RDM?

Thanks,
Austin

Hey Austin! I just joined this site and was wonding if you changed out that fluid! I just changed out my tranny fluid with Mobil ATF 3309. It took 4 quarts but only 3 came out. I have 90k miles on it and I think it was original and it was quart low and it turned to brown sledge! I was going to use Mobil 1 Syn Gear Lube 75W-90 in the transfer case and rear diff! If anyone used anything different please advise! thanks all! Doug
