Unhappy 2003 Tranny problems

I have a 2003 F350SD with the 6L and 5 speed auto trans. It has under 800 miles on it and the tow / haul system is acting strange. At 600 miles I started the truck and found the tow / haul light on (orange light on colum shifter) Pressed the button to turn it to normal operation. now the "ON" light won't come on, when ever I start the truck it is in tow / haul mode. I can switch it back to normal mode if I press the button. When I go over a large bump (railway crossing) it will jump back to tow / haul. The "ON" light does not work at all...... Anybody have an ideas????

I am taking it to the dealer on Thurday... BUT... They said they have not yet had to work on a new trans.... This scares me!!!!

Thanks, DG

It isn't a transmission problem. It's either a wiring problem or a bad computer.

Smile 2003 Tranny problems

Thanks for your comments Mark, by the looks of your profile I would guess you might have an idea about the new 5 speed .

Would you have any sugguestions for me to pass onto the dealership?? They have yet to work on the new trans. This makes me uneasy.

When the first problem happened I started the truck, the tow / haul light was on. I turned it off by pressing the button. The light went off. It then came back on, so I pressed it again. the "ON" light flickered three or four times then nothing. Now when I start the truck it comes on in tow/haul mode (with no "ON" light). I can put it in normal mode by pressing the button. If I put the truck into park it jumps back to tow/haul (no "ON" light) the same thing happens if I go over bumps.

Thanks for your time.

They don't need to work on the transmission. It's a wiring or a switch problem. They have probably worked on one like that before. The wiring is not all new.
