I have a 1996 Ford F350 Powerstroke autotranny Dually and the electronic transmission is acting crazy on me. It shifts perfect although sometimes the push button overdrive light starts to flash on me and it shifts really hard into every gear when driving it. But when the light is NOT flashing, it shifts extra smooth......?
Either way, it shifts good and does not slip at all, but why does that little overdrive "off" light flash and make it shift hard like that? If anyone knows, then please let me know as this is driving me crazy.....
Thanks and you can drop me an email if you would like at:
