First of all hello. I was on another 4X4Wire forum for 6-7 years but had to let my old truck go. I changed all the fluids in my recently purchased '97 Cherokee and in the process I found a 2007 TSB that recommends that the AW-4 auto transmissions now should use ATF+4 fluid. I started asking around and am getting all kinds of different opinions regarding using this full synthetic trans fluid. Any input from you guys will be appreciated.
