Overdrive light on shifter starts flashing, and OD turns off. I have to turn van off then back on and OD light quits flashing and my OD works. Has only happened four times over 6500 miles, but no rhyme nor reason I can tell. Transmission only 2 years old. No other issues. Hwy speed 3 of 4 times. I’m on trip just drove 2,400 miles and OD light came on once. Worried problem will get worse, leave me stranded. Can anyone recommend a decent shop or location to get transmission codes read in fort Worth area, preferably Johnson county.? will the trouble codes be stored even though I’m thinking computer resets when turning car off and back on to temporary resolve issue? Any ideas what I could check for, or rule out? It’s a 1996 Ford e150 auto 4eod trans, 5.8 liter. It’s an oldie, but have had since new. Reliable. I’m no mechanic, but know my van, do own brakes, tuneups, maintenance, etc. money very tight, but if anyone knows shop or mechanic with decent expanded reader…? Thanks, teressa
So the van is nearly 30 years old, but you mention the transmission is only 2 years old.
Was the transmission replaced 2 years ago? Has this OD light issue started happening since you got the new transmission?
Welcome to the forum… There are many many reason why the OD light can/will flash, next step is to go to your local auto parts house and ask them to pull the codes, either write them down or take pictures and post them back here…
Other than that, we are just guessing…
If the OD light is flashing that’s means there are codes. They should be stored. I can’t recommend a particular shop to you, as that’s half-way across the country. Is there any torque converter shudder? That was a common issue and harbinger of an impending rebuild. Hard 1-2 shifting is another ( the computer will raise line pressure to protect the transmission if a fault is detected). I had a 1995 Bronco with the E4OD and all of those things happened before I broke down and had the transmission rebuilt. If you’re not experiencing any of those things, it might just be an electrical issue.
