Jesus christ, this is the most beatin to death topic. At the end of the day, its a fluid...NO fluid is lifetime, so why in the hell wouldnt anyone want to replace it. Even BMW (because they are the holygrail ya know) has even revised their own suggestion of lifetime because they realized the err in their ways. Its now a serviceable item on newer cars, so why wouldn't we retro that same new practice to older cars...which are WELL known to have transmission issues. Sure, no one can prove beyond a reasonable doubt one way or another if changing vs not changing the fluid is a factor is transmission failure, so I revert back to my original statement - absolutely NO fluid is lifetime. Comparing a shock absorber and its 1 moving part to a transmission and its countless moving parts...now that is nonsensical. People...either change your fluid or don't, do whatever makes you happy. If someone wants to follow the (imho) blind advice that BMW has since stopped practicing, that's up to you. I know what I'm going to do, and its far less expensive to do every 50k vs a $4k transmission replacement. There will be just any arguements for as there are to not change it, so to each their own. How the OP turned the title of this thread and combined a transmission poll is beyond me...good job man, see the pot you've stirred
