Od light started flashing on my last tow. Turned the truck off restarted no more flashing light. Tow for a while longer and the light starts flashing again. Went through this scenario a few times on the way home. Been running around town for the last couple of weeks unloaded and no flashing od light.
Speedometer seems normal but it does seem to kind of jump into gear when upshifting.
Meet up with fellow FTE member (thanks again cammodown) and he did a scan for me.
P0741 Torque Converter Clutch Circuit
P1209 ICP Peak Test Fault
P1211 ICP higher lower than desire (engine running)
P1298 IDM failure
Pretty much stock 2002 83000 mile truck except for a Edge Juice with Attitude.
Any Ideas?

 

Can your Edge not read codes? The Edge is known to cause rough shifting issues. What tune where you in when the light was flashing while towing? ICP codes are not uncommon with a tuner, and an IDM failure will leave you stranded on the side of the road. If you've got a dead IDM code and the truck still runs, I'd write that one off too.

The first step would be to set the truck back to stock (completely remove the Edge stuff) and see if the problem repeats itself.

 

Im not sure if my Edge can read codes. I dont think so but will look into it.
I was in stock mode when the OD light started flashing. I pretty much always run my Edge in the stock position. EGTs seem to high for my liking unless Im runnig on stock setting.

 

The P0741 code =Toeque converter solenoid circuit performance/stuck off. that is Ford's wording, idk if it is the same as converter clutch circuit or not.

 

According to my ATSG manual: A trans code P0741 means "The PCM picked up an excessive amount of TCC (torque converter clutch) slippage during normal operation."
Symptom: TCC slippage/erratic or no TCC operation. Flashing Trans Control Indicator Light.

 

OH NO!
Are you saying its time for a new torque converter?

 

Do you have a tranny temp gauge? Just to see if your temps are high. A slipping TC can really heat up the fluid.

 

No aftermarket tranny temp gauge. Just the stock one. I kept a close eye on the stock gauge while I was towing and it never moved. Did have the tranny get hot about 10,000 miles ago sitting in stop and go traffic cresting the continental devide. Towing heavy. Had burnt smelling fluid so drained halph the fluid out and replaced it. Drove another 3000 miles or so and completly changed the fluid. That was the only time the tranny ever got hot since Ive owned the truck.

 

I disconected my Edge junk and no change in my tranny shifting. Check engine light came on though until I hooked it back up.
Tranny fluid did smell a little clutchy but Ive smelled worse on trucks that had no tranny problems.
Tranny still isnt getting hot and I havnt had the OD light flash since I was towing on Memorial weekend.
Tranny seems to jump into gear when upshifting between 30-55mph while (easy criusing) on flat roads. If I hammer the skinny pedal (not easy cruising) it doesnt shift bad.

How can I tell if my problem is the Torque Converter Clutch or if its the Torque Converter Soleniod?

 

Anybody have any ideas?

 

Is there anyone with an AE or scan tool nearby? With the AE, there is a live data meter function that will read slippage in rpms. It compares the trans input and output sensors and gives you the amount, in rpms, the trans is slipping. You watch the rpm when the TC locks. Ideally, you want to see close to "0".

 

No time or $ to mess with the truck.
Will driving around with a bad torque converter solenoid cause any damage to my tranny or torque converter?

 

Got lined up to do a live scan next week(thnx again cammodown your the man).
Ive been driving (unloaded) the truck for about 4 thousand miles with my torque converter issues. No changes in how it drives at all so I dont think its gotten any worse.
Im assuming because it hasnt gotten any worse that its my TCS.

Could I have done any other damage to the tranny driving for so long with a bad TCS?

 

Digging up an old thread but my buddy has the same code so I wanted to see what you figured out. His is on a 2002 F350 CC longbed with the 7.3. He has about 254k miles on it and its all stock.
