I would begin by checking the transmission fluid level. If it's ok, then that means that your transmission has overheated. Have it checked for overheating damage by a professional transmission shop. If everything checks out ok have them add a secondary transmission cooler. This will allow the transmission to cool down faster under heavy hauling conditions. Hope this helps, good luck!

What vehicle is it on? The super duty pickups had this problem and it is a bad temp sensor in the transmission. It is easy to replace you just have to drop the tranny pan. The gasket is reuseable.
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 trans fluide oil for a burnt smell
if so replace ---mercon sp only in power shift trans
anything else will cause damaged
tow haul light fashing = trasmission code
need to scan probably faulty sensor chaff wire
dirty conection /partialy unplug junction
burnt fuse
Does the trans fluid have a burnt smell and is it brown or dark brown as opposed to a red wine color? If this is the case then you may have a service issue caused by a clogged trans filter which is what this sounds a great deal like and the sooner you get the truck to the dealer or your mechanic the better as the trans in these are not cheap to rebuild or replace.
THERE HAVE BEEN ALOT OF PLOBLEMS WITH THE SHIFTER HANDLE/SWITCH. THE BEST WAY TO VERIFY CONCERN IS USE A DIAG. SCANNER & VIEW TRANSMISSION DATA DISPLAY WHILE ENGINE RUNNING. THE SWITCH IN THE SHIFTER IS FAULTY. IF YOU SEE NO INPUT CHANGE WHILE DEPRESSING SWITCH THIS IS YOUR CONCERN.
