you can't do it. if you have new gt.they got nasty and put a dual plug in the autos.the dealer is the only one as far as i've been able to find that can do it.went to have mine done and this is what we found.we can't even check the fluid as theres no stick.this trans is made in france and they put the screws to use as to doing anything to them without changin it out for something else.
