Towed my boat today, and took the truck out of overdrive.


60 miles into the trip, the overdrive light went to flashing.


I took it out of "overdrive", and it quit.


What should I be looking for? No more light......... so no codes??


Thanx

 

Flashing od means trans code

 

O.K., since the light shut itself off, would a scanner still pick it up??

 

Yes it will. It is a soft code, if it quits flashing, but it will be still stored in the memory. A good reader will give you your codes.

 

O.K., will get the code read today.


Thanx, for all the input !!!

 

I had the code(s) read today. The code said that it was a overheating problem.


BUT, I lost the dadburn paper that had the # on it !!!!!!!!!!

 

Overheating means you scorched the tranny fluid also. I'd do a tranny filter change asap, if it was me. The old fluid loses it's base, and makes the trans shift funny and does all kinds of damage if left untreated. I'd definitely go with new fluid.

Your codes were probably P0713 for the sensor, or P1738. I'm guessing, but these are the common codes for overheated transmission.

As far as overheating, time to add a transmission cooler. It will save you from this problem happening again. Flexalite and Hayden and others make coolers that can be installed by anyone and give you the piece of mind for a cost that doesn't or won't usually break the bank. Good luck and glad you found the problem.

 

The truck does have a cooler, so, now, I'm wondering what could be wrong if anything with it.


Changing the filter out, doesn't bother me, but am concerned about the "new" fluid causing a problem down the road. The truck has 156,000 on it.


I mean if changing it out is the solution, I've not got a problem with that.


I am wondering if there is a part, say a solenoid, or something that is acting up.


Thoughts??


P.S THANX for your thoughts, info, and response !!

 

When you change your fluid and filter (service in general) you only lose about 3-5 quarts of fluid. The balance (7 or more quarts) is still in the transmission and converter. The adding of new fluid, brings back the properties that are needed to shift correctly and give good lubrication to the hard parts, lost when the fluid gets overheated. You don't have to worry too much about doing a service, as long as you don't drop all the fluids. Even then, it is quite possible to have a great or even better transmission, because of the upkeep. Two way street actually. lol

Even with a cooler, if the weight and the angle of the hills are a lot, then that puts a lot of strain on your transmisssion. When it gets hot, it is because the fluids aren't being cooled significantly. Maybe your cooler is too small for what you are trying to do with your truck. I don't know your boat, but I know if I pull my 18ft up the hills, my temps tend to start rising, so I back off a bit and they stay cool. I don't have a cooler, but will next summer. lol. Your situation reminded me that I need to do this. Good luck.

 

I will be using MotorCraft fluid. AND a MotorCraft filter.


Doesn't the rear end, get a friction modifier?


I've got to crawl under it and count the bolts, I guess to determine which trans, I have.


I searched through my VIN #, and really didn't get an answer as to which trans I have.


It's a 5.4 with towing pkg.


Lucky for me though, I work part time in a parts store, so I can save a few pennies !!!
