i've changed the fluid on my camaro's and trucks in the past but not on the element yet. i just had the dealership do the tranny service and they suggested to change the rear diff. fluid, they offered to do it for $90. so i bought the fluid while there and decided to do it myself. have n e of u guys changed yours yet and do u have any pointers or even the repair manual specs?? n e and all advice is greatly appreciated
