Flashing OD Light
 

Tonight on my drive home from the mall I noticed the OD light blinking, I do not remeber noticing it doing it on the way to the mall. I shut the car off and restart it and it goes away until I start driving again ofcourse. Now yesterday I pull starterd an old Dodge Power wagon I have been working on. It didnt seem like I really jerked my truck that hard. I'm guessing I messed something up in doing that. I really dont know. What could possibly happen by kinda lugging on the transmission when pull starting some engine. The transmission use to sometimes kinda slip between 3rd and OD the engine would rev like the clutch was in then it would go in smooth. But it has done that for 2 years. In pulling that truck I was going down hill not like it took that much power.

Something I just thought of I went from a 225 or 235 tire "whatever the door jam says is stock" to a 255 tire. So my speedometer is not accurate anymore I put those tires on about 3,000 miles ago though. With all the trips the computer goes through didnt know if that could be the problem still?

Not sure about light, but on same F150, 255/70/16 are standard tires. That is what I have on my 1998 4.2 auto supercab.

I dont remeber extactly which one 225/235 it was but they werent 255. Maybe they only put the small ones on the single cabs.

235/70R/16 was the standard tire.
255/70R/16 was an optional upgrade
unless the truck had some trim upgrade, then they threw in the tires to sweeten the pot.

If your OD is blinking, a code is stored.
Go get the code read.
It could something as cheap as $69 that could save you from doing damage that could later run you $$$. (plus tax) :)

I know AutoZone will read any codes for free.
Still have window sticker for f150 in sig, tires not listed in options.
Still has 255/70/16 Wranglers on it. (truck is regular cab xl.)
Just my two cents.

well took it to my friends shop and he said its just a shift solenoid should pick up the truck tomorrow.

was the 2-3 shift solenoid bout a $100 part transmission looked good and the pan was clean.
