Our Synergyn transmission fluid is a great product, a tad tough to shift when the tranny is cold, but other than that its great. I havent broken 1 transmission since I made the swap, like I said, cold shifting kinda sucks but most of our customers remedy that with a splash of BG or Redline combined with the SynGear II. Will it stand up to the abuse? how about 30 psi, AWD, and burnouts sound for you?
