My 1999 Sonoma has about 80K miles on it. Tranny is 5-speed manual, uses GM synchromesh transmission fluid (i.e., not gear oil.) No problems with the transmission but still I am wondering if that fluid should be changed. Owner's manual says that, unless you have been underwater, you never have to change the transmission fluid. "Never" seems like a long time. Does anyone have an opinion and/or experience to shed some light on whether this indeed needs to be changed?
