I obviously agree with the consensus (albeit not 'scientifically' proven) and won't be using Mobil 1 in my 89 gen I auto tranny. If someone proves that it's safe, then I would certainly reconsider my opinion but being that I don't drive it daily and probably only need to replace the fluid every couple of years, I probably still wouldn't use Mobil 1. <img src="/forums/images/graemlins/lol.gif" alt="" />

All that said, one thing though is Scott's Mitsu is a gen II and not a gen I. Is the build and design of both the same? Do they use the same internal materials? These are all unknowns to me at this time however seeing Mobil 1 AT fluid's track record with Mitsu Gen I Auto Transmission's I'm just not that much of a gambling man. Additionally with less than 10k driven on my 96SR each year & the track record of this tranny's reliability using regular dino based tranny fluid, I think I'll be ok just using plain old mitsu tranny fluid. <img src="/forums/images/graemlins/lol.gif" alt="" />
