How do you change the fluid on the 1999 ZX2 with an automatic Transmission?

you need a machine like a t-tech other wise its darn near impossible

Is the t-tech machine a flushing method? Just want to drain whats in the pan and add new fluid. Leave filter intact.

well if you drop the plug you only get about 30% of the fluid. if you want that make sure you got a dip stick, if you dont then you cant. if you do call the dealership and see which transmission fluid you need and how much then drop the plug drain the fluid then fill through the dipstick
