O/d Light Flashing On 1993 Es300 Automatic

Recommended Posts

my o/d light is flashing, the vehicle drives sluggishly, not like there is resistance, just that it takes higher than normal engine speed to get the vehicle speed to normal levels. in reverse, it seems like everything is normal. also, my cruise control will work for a minute or so, then it surges a few times, and the cruise light blinks, and then cruise control goes off. after this happens the cruise cannot be turned back on unless the vehicle is shut off and restarted. i mention the cruise issue because i think it might be related to the blinking o/d light issue. the cruise issue happened first, before the transmission had any problems. i will not drive the car with the transmission functioning like it currently is, so i can't test to see if the cruise issue is still there. i have only driven the car around the block since the o/d light started flashing. also, on a related note, the speedometer will sometimes stick when you first drive the car. it remains at zero. if you smack the dash board lightly, it will pop up and begine functioning.

is there a way to check the transmission codes? can someone walk me through this?

from what i have read, this might be the vehicle speed sensor malfunctioning. the engine and vehicle seems to be working flawlessly other than these few issues.

ok basically i checked the code and got code 62 for the transmission which is 62 - Open or short circuit in no. 1 solenoid valve.

anyone have any experience changing the vavles?

the transmission is also overly full of very black, very old transmission fluid. i dont want to change it for fear the transmission will never work again.

I am having a similar problem with my 1993 ES 300. Can you tell me where I can find instructions on checking the code. I may have the same code but I dont know how to scan the code, since my car uses an OBD1 system.

Thanks in advance.

the transmission codes are retrieved by jumpering DG and E1 with a paper clip in the diagnostic connector in the engine compartment - if you have a shift solenoid code the solenoids are mounted to the valve body under the trans pan

Thanks for the info. When I tried to retreive the codes, I saw that my battery was dead. So I used jumper cables and started the car and charged the battery, before I could check the codes again. The light was blinking steadily which i interpreted as no codes. Is it possible that the codes got wiped out due to the battery going dead?

TIA

why don't you try going to an actual transmission specialist that would probably be the easiest for you if you're struggling to try and get codes. and if you're having o/d flickering THEN TURN OFF THE OVERDRIVE. that's what i did on my car when it gave me that issue. it's really not that scary if you just disable it. but yes get that transmission checked out or try o/d on with ect power on and see if that helps. if it does might be that you need a new battery. but yea i'm just going by my experiences with this issue. hope this helps.
