99 GP GT Trans

Hey, i've got a 99 gt and was wondering what the life is on the trans fluid. I've got 37k on it and people tell all mixed stories on when, if ever that the trans fluid needs to be flushed and refilled.

any input, thanx

I wouldnt flush it, just do fluid change.

Too many horror stories going around about trannies going bad after they are flushed.

ok, so how often should i change the fluid, or is it set up for 50k miles?
