87 camry has overdrive light blinks on & off

If blinking in a pattern, the number code can indicate an electrical problem with one of the solenoids.

I don't believe it blinks in any particular pattern, just on and off at a constant rate. The blinking does not occur everytime I drive the car and it doesn't appear to be temperature related. It has blinked when the car was cold and other times it has started blinking when the car was warmed up.

One thing I failed to mention before was that the transmission does shift correctly. I watch the tachometer and shifting occurs at the proper times so I agree with you about a solenoid problem. Any suggestions on which solenoid and could I replace it?

Try taping down the button....it may not be making complete contact. I had the same trouble on my old 87 Camry and just placed a coin over button and taped it down.

System has detected a malfunction.

I don't understand???

Well ... a BLINKING light does SUGGEST an error has been logged in the transmission's ECU. Do you understand that part? There are electric components (solenoids and sensors) in the transmission.

Yes, I understand that. Is there a listing available to the public which lists the error codes so I can possibly figure out which component may be malfunctioning? I would prefer not to take the car into a transmission shop, I have had a few bad experiences with a few of them. Even if I cannot fix it myself, I will have a idea of what the problem may be when I take it in. Thanks.

Regrettably, I can't help you with a transmission code list.

Thanks anyway for the help.

I have the shop manual for an 1986 Camry. I don't know if the '87 is the same. I can scan the pages and e-mail to you if you like.

Thanks for the transaxle code listings. I checked it out and two error codes are stored. The first one is code #62 which is "Severed #1 solenoid or short circuit- severed wire harness or short circuit. The second code is #64 which is "Severed #3 solenoid or short circuit- severed wire harness or short circuit.

I checked for any broken harness but I am not sure where I should be looking. Any ideas where I should check for these problems? Is it something internal to the transaxle or can I see the solenoids or wire harnesses? Thanks for any help.

In my 94 Camry v-6 it was simply dirty (oxidized) overdrive switch contacts. Pull the button off with some plyers and spray contact cleaner (Radio Shack) into the switch. Use extention nozzel and work the switch in and out after spraying.
