Im pulling this from the dead, but I am long overdue for a tranny fluid change @73000 mi. I have heard and read different opinions on this. In the past I have always gone with tjkj2002 aproacch and took it somewhere it could be fully flushed. After reading some online discussions though and talking to some friends they say this is not good. Forcing the fluids through the tranny can cause some sort of problems...although they couldnt really elaborate on it. Is there any truth to this at all?
A trans flush does not force fluid through the trans,it also does not "reverse" flush it either/Good trans machines use the trans pump to pump the fluid.Just opt for them not to use any chemical cleaners,and yes the dealership is the best to have this service done as they will use the correct machine and fluid.
The problems you hear about is from poeple that had underlying trans issues before the service to begin with and the trans was going to fail either way.
