Od/off trans temp light comes on. had fluid and

2000 to 2500. If your not sure the OD is coming on. At 55 MPH, pull the shifter lever down to third gear. If no change, you have no OD. The most common problem with this is that the governor solenoid goes bad. It has the Temp sensor built in. About a $100 fix. Sensor,filter and fluid.

OD probably is commanded to go off whenever the trans temp is high. Was the radiator connection plugged when the cooling lines were removed? Check to ensure they are connected to the radiator and were not kinked when the engine was removed.

Hi, I have a 2004 Dodge Ram 2500, 5.9 Cummins with 225,000 miles. Just today, my Haul/Tow keeps coming on and Trans/Temp light. Keeps automatically switching in and out on its own. It's been 100,000 miles since my last trans maintenance. Going to a mechanic close and he suggested to start with fluid change, filter change, and inspect the band, maybe adjust. Trans runs very smoothly. Checked the fluid, looks clean and not hot. Is this common with this year and mileage? If so, whats normally the out come? If the band is bad, do I have to replace the entire trans?

CHECK YOUR WIRING MAY BE IS SHORTED OR CUT,SPECIALLY WHERE IS NEAR EXHAUST OR ANYWHERE TOUCHING ANYTHING,

many possible causes,
tires too large brakes dragging???
;possible torque convertor problems,
outside air temp sensor for trans probs
ECM /electrical connection /lockup issues
Trans may need a service?? change oil & filter
Is this a high miler??
Has it sent up any fault codes?

P1740 TCC Or OD Solenoid Performance

Bad solenoid

the valve body has a vavle stuck in the trans you could take it in and have it fixed at a trans shop or take the pan off the trans figure out which is stuck free it up and maybe put a spring behind it if possible on that model.

Check out oil cooler is not ckocked.

No, the codes were not scanned that I am aware of.

if your vehicle is a diesel truck then removed transmission pan. removed transmission filter as well. you will find wiring going to two solenoids side by side. follow harness to other sensor. single solenoid which is located on governor. there will be a square sensor on side, should be black in color. that is your temp sensor. make sure to replace the governor and sensor together. they can be bought seperately but not advisable to just replace temp sensor. should range in price of $200 for both.
