OD Light Blinks intermittently

So I have had an intermittent issue with my E4OD going into a safe mode. The light starts blinking and the shifts are hard. What signals does the transmission get. Where is a good place to start testing signals? What is common with this symptom?

Could be a multitude of things. The best place to start is the FIPL (TPS on a gas engine). PRobably getting a bad signal or the FIPL is bad. Just a place to start. If you need help testing it let me know.

The fipl is the sensor on the injection pump? I think its also called the potentiometer? I have replaced that twice. So I don't think that's it. What would you recommend next. The fluid doesn't smell burnt and doesn't have metal shavings in it. I was going to change the filter and fluid soon anyways since I just bought the truck. I was considering welding in a temperature sensor, but I don't think its overheating.

So i jumped the eec wires and got three codes.

97- E4OD OD cancel light circuit failure - Transmissions
23- Throttle sensor out of range or throttle set too high - TPS
62- this says circut to ground failure 3/2 or 4/3 and it also says,
E4OD excessive converter clutch slippage - Transmissions

Does anyone know the range that the potentiometer should read?

Voltage is right. When I opened up the pan yesterday I found some loose valve body bolts. I tightened them up and welded in a temperature sensor. I haven't had the issue again. I have not pressure tested it but I am confident that that might have been some of the issue. I am going to run it a bit longer and see what it does. I will post back as soon as it comes up again.

in the low part of the pan, where the drain plug is. I did it coming out towards the rear of the vehicle from that 4 inch by 4 inch sump area. Just welded in a 1/8 stainless bung. I just wanted to make sure it wouldn't interfere with anything or hang to low that it will get cut. So far i hit 180 in traffic on the highway. I haven't loaded it up much though. Any idea on operating range?

Thats fine for temps. I wouldnt let it get much over 205 or so before taking corrective action.

Have installed a auxillary oil cooler or do you just have the stock one? Permacool has some good choices for coolers. Once I put mine on I had no worries about temps!
