2002 Celica ATF HELP

[josalbrec]

I Have an 02 celica GT. at 44K miles I went to Valvoline (of all places) and they used Maxlife ATF to perform a tranny flush. I was assured at the time that Maxlife ATF was compatible. I have read and researched online for weeks and found that Valvoline basically says Maxlife will work for Toyota, however, that has not been tested by Toyota. WELL, The celica now has 66K miles and occasionally when I take off from a dead stop, I hear a very small skweak. It is very slight and doesn't last very long, however, I am concerned. I am a daily driver and don't "hot-rod" my car, in fact everything is factory even the airfilter. Any Thoughts??? I am thinking about having the toyota t-IV fluid flushed into the system to see if that helps. Any thoughts or imput are welcome. Thank You!!
