Ok my car has 94 thousand miles and I want to do the transmission filter and fluid. My question is I want the very best synthetic transmission fluid I can get. I had jiffy lube suck the old fluid out and put new in but I need piece of mind when I go WOT that I'm getting the best performance I can while eating some Honda's. Also what mods can I do to my car, its an automatic transmission? Also what's the best filter?
