assuming you have a tip:

the tip wasn't built to be regularly serviced. it's supposed to be "lifetime" fluid. that said, yes it can still be changed. to do so you'd need to drain the current oil, drop the pan, replace the gasket, replace the filter, put pan back on. fill through the same hole it was drained from until it starts to come back out. run the car until the transmission gets to a specific temperature (i believe ~95ºf). fill until the fluid starts to run out. get back in, run through the gears and top off the fluid again.

i'm at 103k miles on the original fluid, fwiw.
