DO NOT DRIVE YOUR TRUCK!!!!!


I had this happen and it was when my tranny overheated!!!! Take out the dipstick and smell it, you will be able to tell just by that. Also, you will want to take your truck in and get a tranny flush...that is where they actually pump out ALL the oil and pump fresh stuff through it, then refill. It will extend the time you have on your tranny by a lot.

Write for more info if you have to get your tranny rebuilt, there are several things that I would reccomend having done when it is rebuilt to stablilize the tranny and extend the life dramatically. Also, what all do you do with your truck? Haul? 4x4? Race? What kind of loads do you put it under?

Good Luck

O/D light flashing usually indicates a sensor or wiring fault.

I have a 97 F350 and it happened to me, had to have my torqe converter replaced(was on the hiway when it happened).

This happened to me 200 miles from home. Called dealer and my mechanic. Both said to disconnect batteries (2) for 2 minutes and then reconnect. This reset the computer so I could drive home with overdrive. (410's without overdrive is major RPM's or a long slow drive). By the way this reset lasted 5 days before it did it again. I had my fluid and filter changed at 30K intervals and the truck had 114k miles on it.
The Ford garage tested the computer and got a code of "Trans Slipage Detected". I took it to a trans dealer and he got the same code. He talked me into a remanufactured Jasper that lasted 1 month and it did the same thing. The trans shop checked it and found a faulty modulator valve( that they took out of my truck and installed in the Jasper) I still feel to this day that my trans was OK just a bad modator but how would you prove it?
That transaction set me back $2,500 but since then it is fine I have 148k now and 2 years on the new trans.
PS. The Jasper came with a 3 year 75K warranty-That was better than a factory Ford from the crate and Jasper builds in all the upgrades when they remanufacture it plus the warranty is nationwide. They will tow the truck to their nearest authorized service center.
Good Luck

a flashing OD light could mean a multitude of things, and the fact that you had a high temp warning for a code makes me leary. only one thing causes high temp, excess friction. sometimes it is due to poor cooling not taking the temp of the fluid down, but 80% of the time it is due to slippin clutches in either the trans or torque converter. if you need to get extra life out of that trans, i would reccomend an extra external cooler and to drive it only in the stock setting if you use a chip. drive it nice and easy, because there is a decent chance your building a tranny problem...and this was just the first sign......Marc

Give us an update...how is that tranny doing so far?

Had the trannsmission flushed but after about a day the error code was back. Found a magnafine filter and ordered a replacement, the code was intermittent. It seemed to throw the code when the truck was ideling for over 15 mins. But when it under 10 mins idle time the code was not there. But since the magnafine filter i have not seen a code. Been 3 days so far. Maybe there was to much of a restriction in the inline filter.
