Hi,i bought a 99 4dr 2wd jimmy last month and havent droven it since i dont know how to read the tansmission fluid stick,it's wierd.cold at bottom and hot at top,where should the fluid be?i checked it cold and it shows good and when i warm it up it shows barely anything touching the stick.my brother towed it from where he lives.he he changed the tranny fluid and added some slick 50.i drove it a few times untill i checked the tranny fluid and dont know what im doing wrong.i know theres fluid in there but why does it dissapear when it warms up?no leaks either.
