I just got through putting my new (used 22k mile) transmission in, it shifts fine except it wont shift into overdrive. Also the tow haul light starts flashing when it shifts from first to second. It doesnt give me any codes but I can turn off the tow haul light with my scan tool.

 

You may have a stuck or bad solenoid in your Transmission,
I had a 2004 with the same issues at 14,000 miles.
Can not help you with witch one it is, I had the dealer fix it.
Check your wire connections to the transmission.

 

I have an update, After you first crank the truck it will shift fine through first, and second then it has a bit of a clunk as it shifts into third at the same time the tow haul light comes on and begins to flash. also if you hammer the gas the tow light will come on and it shifts into third. It will not down shift either. also the 4WD low range does not function, I have unplugged the battery twice with the same results.

 

Ok Im an idiot, I read the manual and it explained how to put it in 4 low and it works fine. But I still have the same shift problem, once it gets to about 1900 rpm it wants to go into 3rd and not come out until you turn it off and on again. Even if you come to a stop it stays in 3rd. I swapped the sensor on top with the one from my old tranny, it looks like a speed sensor, I guess anyway same result. Im off to the stealership Monday for my raping because my new OBII sensor that is supposed to be CAN compatable will not read the code when the tow light is flashing, but it will turn it off?????

 

I did not want to give you the bad news yet, but mine went in for a overhaul after the Dealership up dated the Solenoids. It got so bad that when I stopped at a light the Trucks engine killed.

 

The trans will have to re - learn it's shift strategy. There is a procedure for this - unfortunately the link in the Tech folder no longer works. Hopefully someone has a good link for that.

Note - the Tech folder has been updated.

 

That's not going to help. The relearning the shift pressures will only help with shift smoothness, he's got something wrong.

The only way to fix this is to find someone that can read the code that was stored when the tow/haul light flashed. That will tell you what's wrong.

 

Mark,
Im taking it to the ford dealer tommorow to see if they can pull the code. I still have my old tranny, Just in case it is a solenoid, I was thining I could use a good one from my old trans. I have checked them with an OHM meter and all but one are showing 4.5 OHM except for one, its on the far left of the row with four solenoids, it is showing about 5.4 OHM. Do you have a way I can test with my multimeter? Can I put 12v to them and see if they actuate? with that destroy the solenoid

 

You can put 12v to the solenoid and see if it actuates. It won't hurt it.

 

Took it to the Ford dealer this morning, took about 30 min. Hooked it up to the scan tool and found code P0720 "OSS sensor not plugged in correctly" All is well with my new tranny now. I will be replacing the egr cooler Im going to block this one off, and a new oil cooler (oil in my coolant tank) The guys in the shop told me to just use freeze plugs and 3M sealant on both ends of the egr cooler, He said his has been done that way for 30K with no problems, Also they said the truck was missing on the #6 cyl. and it had a couple of egr codes that were set off, they said to check the Y pipe when I do the cooler. Im just tickled that it only cost me $64 for the tranny.

 

right on!. that don't happen very often. did they give you a reason for #6 misfire?.

 

I have read where folks have trashed a turbo due to a freeze plug mod on the EGR cooler.

 

They said it was the fuel injector. I just bought a new one off of ebay $129 shipped it was the only one he had, I thought that was a great price for a new one, the rebuilt were 150+. not including a core.
