Hi to all. Im new to this site, but I have read a lot of stuff here and learned some. I have a 2004 f-250 super duty with a v10 and a 4r100. This truck only has 68,000 miles on it and has preformed well. We use it to tow sometimes, but its mostly just drove. I change the oil regulary and had the tranny flushed around 10k miles ago. Everything has been working fine on it. Today when I got off from work it said to check gauges and the o/d off light was flashing. It seamed to shift a little harder than normal, but not by much. I pulled off the road and cut it off and started it again, but it still had the check gauges light on as well as flashing o/d off light. It did go in and out of overdrive while it was doing this. After 5 mins it went back to normal. I don't know what in the world would have caused this. Everything else on the truck is fine, no other lights, no weird noises, no messed up gauges, nothing. Please help.

 

I searched back in the forums and there was another guy had the same problem and the code was internal transmision slippage. I sure hope this isn,t my problem or else i will be very disaponted. The truck has only 68k miles on it. Also my speedometer is not bouncing around at all, its fine.

 

your going to need a code scanner, but if the light was flashing there is def. a code stored.

 

Ok I checked it out this morning with my tuner, hypertec max energy econ, and it came up with p1000 and p0713. I don't know what those are. I drove it some this morning and it did fine, no lights or problems. Im so confused

 

P1000- OBD System Readiness Test Not Complete. (My 2003 Always has this as well. Think it has something to do with only being OBD1)

P0713- Transmission Fluid Temperature Sensor Circuit High Input. (Maybe a bad transmission temp sensor?)

Tim

 

I was thinking it could be something with the temp. Last night it was cold, around 20, and as soon as the lights went off my tranny temp gauge started to come up to normal temp. Thanks for those codes.

 

I just installed a Hypertec max energy in my 2004 f-350 v-10 A p1000 code pop up and I called Hypertec and they said it was nothing. Its from the tunner.They said just delete it.But overall how do you like your programer?

 

I overheated a transmission once by having my Throttle Position Sensor unhooked. Blew fluid everywhere past the pump seal. It overheated because the torque converter was UN-locked the whole time... Slippage / heat. Hopefully its just a sensor and not a torque converter staying unlocked situation?
What did your tranny temp gauge say?
I'll see if I can find out how many temp sensors it has ?

 

Alright- A Lot to this. Hope it helps and is readable !

PINPOINT TEST B: TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR

NOTE: Refer to the Transmission Vehicle Harness Connector illustration preceding these pinpoint tests.
NOTE: This vehicle is equipped with a transmission fluid temperature gauge in the dash. The transmission fluid temperature gauge may be used as a quick reference to the operating temperature. It should not be used as a diagnostic tool to tell the temperature of the transmission. The WDS, NGS or transmission tester should be used to obtain the actual temperature of the transmission.

Ok guys thanks so much, you all have helped out a ton. I did drive the truck today and looked over everything its its fine. I went by autozone and the guy didn't know anything about the p1000 code. He said he had never heard of that one before, but that it looked like it was unimportant. Im not worried any about that code. He did confirm the temp code. I explained the situation and told him I cleared the codes and that everything was doing ok. He suggested that I run the truck until it acts up again since its doing fine. He said its most likely the temp sensor or the wiring. He couldn't order either, said I would have to get it through ford. He seamed to thing replacing the sensor would be an easy thing. Anyways to make a long story short the truck is doing fine and im going to run it untill it does this again and then fix it. Oh and yeah I like my tuner, but in hindsight I probably wouldn't pay 350$ for it.

 

Is it the econ or the max energy??

 

It says Hypertec max energy e con

 

How long have you been running the tuner? I would take the truck to a shop that has a good scanner so you know you will be getting all the codes. Autozone and tuners are not good scanners. Go to a dealer or a trans shop and have them scan for codes.

 

This is why a got a ScanGauge II. Aux. actual numbers for the trans. fluid temp. are invaluable.
