Please Help! - Trans Fault - O/D off Flashing - Nasty Noise
2006 F150 5.4L 4x4
The other day my truck was in 4High when I started it up and went to move it. I switched it to 2H and started out, but the O/D off light started flashing and the Trans Fault message came on in the display. After shifting through some gears and back and forth between 4H and 2H, I finally just shut the truck off and when I re-started it the warning light and message had cleared. Hoped it was just a glitch, BUT... today I had to drive my wife to the hospital and on the way I started hearing this nasty grinding sound from the front left wheel area. It was a bit of an emergency, so I couldn't stop. After getting her checked in, I went out and looked around under the front, saw nothing out of place and test drove it for a bit, switching into 4H for a while and then back. The noise persisted, but then it stopped and after driving around for a bit it stayed quiet, so I hoped that it would stay put. Driving back home it was good most of the way, but then it started up again.
It's really nasty sounding, like a ratcheting noise, and the steering gets tight, then it makes this whirring sound and with a clunk it stops and seems fine, but it just starts up again a few seconds later with the ratcheting. No warning lights or messages though.
I know it needs to be looked at, but does anyone have any idea what might be happening.
The timing for this couldn't be worse, I just found a buyer for the truck, which is in excellent shape otherwise.
Any help is greatly appreciated.
