Review on 🔧 Genuine GM Fluid 12378514 Versatrak Transfer Case Fluid - 16.9 oz.: Premium Quality & Optimal Performance Guaranteed by Kevin Singh

WARNING. These are 500ml bottles (just over half a quart). On my Buick Rendezvous, I heard a thumping noise coming from my rear differential. It almost sounds like you're driving at higher speeds in another car with all-wheel drive on. After doing some research I found that this is a common problem where the fluid gets dirty and needs to be changed as the car ages. After switching the fluid to this Versatrak fluid, my rear differential went silent again. There are no complaints about this liquid, except that it has to be bought in bottles of 500ml and not liters.
