E4OD blinking overdrive light
I have a 1991 F350 crewcab Banks-turbocharged diesel. Since installing the new turbo the overdrive light blinks constantly. Anyone have any ideas on this? Might the Banks transcommand cause this?

E4OD blinking overdrive light
i been going thru all the post on E4OD...
i got 96 F-250 with 146k miles, fluid pump at 85k and fluid pump/filter change at 146k...
after lifting truck 6" and putting on 35" tall x 16" wite tires my light will do the same in OD on the highway... i dont have Trans Command installed but was thinking of it. never knew this tranny was this problematic.
i think mine is overheating, has an aux cooler. my OD light blinks with a slight twitch of the spedometer. its like i have to give it a little too much gas doing 70 on the highway, pulling less than 2k on the tach on OD. i been babying it around in fdrive and keeping under 65mph with no more problems... other than one day at a light is was like it was stuck in a higher gear... brought the rpm up and it shifted hard into a lower gear... drove home on hwy (cooled off maybe?) and all is kinda normal again.

The transcommand might cause this. There is a cheap way to find out: Get a code reader. A code reader for your '91 should cost about $25 at most auto parts stores.
Get one, read the codes, post them here, and we can help you diagnose what's wrong.

Most '96s changed to OBDII. OBDII is On Board Diagnostics Second (II) generation. The cheap code readers will not work with OBDII vehicles.

Went off after a few days. I think the ECU and transcommand had to work things out between them! Had it for 7 months and haven't had any problems. Benjamin
