My 5r110 decided to let me down yesterday. Had to get it towed back to the house.
Here's what happened:
I was going about 50mph and was slowing down. torque converter was locked. Now, my TC always unlocks around 45mph or if i let off the throttle... but this time i lost all power to the wheels. Absolutely nothing. Got her over to the side of to road safely and tried different gears. when i put it in drive or reverse i can feel a little bump but when i hit the throttle it goes nowhere and the tow/haul light starts flashing. fluid levels are fine and smells normal.
Now flashback to last weekend: i was towing my boat which is only maybe 4000-5000#. i went to use my tow/haul, mainly for the engine braking, but as soon as i let off the throttle instead of holding that gear and using the engine braking, it simply quit working and the light started flashing. everything continued working fine i just didn't have tow/haul mode. Truck ran fine all last week as well. i kinda forgot about it and went about my business.
Now back to today. talked to my ford dealer friend and he said it could be the wiring harness inside the transmission, given all the symptoms. so i drained the fluid, dropped the pan and checked all the wires i could see. fluid looked fine and relatively clean. nothing looked bad to me so i cleaned up everything and put it all back together. started it up and still have the same problem.
truck is a 2006 f-250 CCSB fx4 157xxx on the clock. mods are generally mild: intake, exhaust, arps, SCT with custom innovative tunes. last full transmission service was done at the dealer with 100k miles. also note, i pretty much run the extreme race file all the time.
Any ideas? any help is greatly appreciated.
