F-350 transmission OD light?

I have an 01 F350 with the 7.3L. Auto with 4R100 trans. Owned it since new and it has 98 K on it. No trans issues. Fluid was flushed/filter at dealer at about 50K miles.

In October I used an Edge Evolution programmer on the computer after driving a friends truck with a tune installed. As the truck is stock I set it to the lowest tune, the Tow mode. Supposed to add 60 hp and 100 ft lb of torque. Also reprograms the shift timing. The truck ran great and felt better. The main thing I liked was the snappy, firm shifts. Only issue was on very light throttle it would shift from 2nd to 3rd and then to OD while only having been in 3rd for 1/2 to 1 second. More throttle would cause normal shifts.

Last week I noticed that on cold mornings the overdrive "off" light was flashing on the end of the gear shifter when I would first start it up. Putting it in gear and runnign through the gears with the shifter and the light would stop flashing. Truck ran and shifted normally. Couple of days ago I used the programmer and returned it to the stock setting and the overdrive "off" light issue went away.

Would like to keep the tune but not if it's gonna cause the trans to get messed up.

Ideas?

Throw the edge in the trash, get a reg tuner or chip that doesnt raise ecp and get an accumulator body modded for the trans to deal w the added power.


Edge evolution on a 7.3 is a known tranny killer. Id also get the codes pulled and see why the light was flashing.

It didn't set any codes. Already checked.

AFAIK, this Edge belonged to you at one time. I got it from Ward, who told me it was yours. His truck came with another tuner and he never used it.

Dont recall ever having an edge for a 7.3, been too long so there is no telling, i may have ended up w one in a trade or something. Is it a tuner to reflash the pcm or a unit that plugs into to connectors and stays on the truck?

It plugs in, saves the stock program and reflashes to one of 3 tunes, Tow, Race, Extreme, then you unplug. You can leave it plugged up if you wish to get realtime engine readouts to monitor things.

Ok thats a different deal, can you set trans settings to stock and leave the engine tune?
