Tranny still slips after fluid change
Fluid that is 2 days old is already brown. I had to use the best ATF SPIII equivalent I could find. The Mitsu Dealer parts dept was not open on Sunday. After fluid change it did not slip at all. Yesterday it slipped once and today 3 times. Mainly after quick or hard launches. I'm sure the fluid that was in there before was not the right one. I knew it was going to mix in with whatever was left in the Torque Conv but wow it's now maple syrup. Going to buy the correct fluid tomorrow but IS THE DAMAGE ALREADY DONE? It will not slip if I drive like grand ma. I plan on doing a full tranny flush this time rather than dropping pan and refill, I already did that and the pan was pretty clean, not much shavings at all. I work on Detroit muscle and sometimes Toyota, Mitsubishi world is toatally new for me.
So will I waste my time spending $68 for new dealer brand ATF fluid? Please help...I stop doing the weekend "honey-do" list and my wife is getting on my nerves!!!
Thanks in advance
