Have 2000 Infiniti G20, ~ 30 K miles on it. Car was running fine, got 25+ MPG all the time. After the 30K mile service visit, the tranny started slipping. MPG is now ~ 21 MPG. The tranny slipping is intermittent, and after a severe episode the overdrive light will flash for about 5 to 10 seconds. Took it back to dealer. They found no problem, didn't seem to know what the flashing OD lite means, and charged $160 for a flush and fill on the tranny!
It is still happening. Called Infiniti, and they will not say what the flashing light means- must rely on dealer to diagnose problem. The only good news is that with each visit appointment, I get to drive a G35 for a day while they ponder the G20 problems. The car is under warranty....
Any ideas what the story is? What does the flashing OD lite mean??
Thanks...
