I have an 86 740gle b230f engine and ZF22 trans. When I driving every once in a while the car seems to shift into overdrive too early and then back into third then it shifts into overdrive at normal power. I can't really tell if it is overdrive or if it is a lockup converter. I don't even know if this car has a lockup. I recently bought this car and it has always done this, I flushed the fluid and tried adjusting the kickdown cable, looked in the faq, no help. What causes the tranny too shift into overdrive? any ideas on what could be wrong? Your help is much appreciated.
