TRANNY FLUID
 

I want to change the fluid and filter on my 99GT auto and just want to see what type is the best.I've heard good things about redline fluid but do i just get a Ford factory replacement filter?

------------------

i would get a factory filter. as far as fluid goes i dunno, i used mobil 1 synthetic or valvoline. how do you like the auto?

"how do you like the auto?"

My auto seems strong enough, but the shift logic under heavy throttle bites. Sometimes it hangs unless I back way off, other times it upshifts way before I'm ready. There's no pattern to it either, like there would be with a misadjusted cable.
