overdrive light flashes on 1990 Toyota Cressida

flashes continuosly whilst driving over drive gear seems to work correctly

Asked by for the 1990 Toyota Cressida
If the over drive light is flashing there is a transmission problem that needs to be looked into. Check the fluid level first and after that have a checked out by someone knowledgeable with Toyotas or a transmission specialty shop. The Cressida transmission is a good durable transmission.
when it s blinking it indicates transmission is the check-engine light for the tranmission.trans shop can pinpoint specific problem.mine went away after i disconnected battery cables
