Last night on my 05 LE I was driving home in bumper to bumper traffic. For some reason my Nav system wasn't working, it only showed radio functions and AC etc. I had this happen one other time when I had my 04 LE, and I just turned the mada off and restarted and it was fine. Last night since I was in traffic, I put the mada in neutral (was probably rolling about 25 mph or so), turned off the key, waited a second, and restarted the vehicle, then put it in drive. Vehicle was in 2wd at the time. A few minutes later I noticed that when I went to take off the veihicle was really "dragging", and straining to pick up RPM's, I thought the tranny was slipping. It was down pouring and freezing rain in the middle of no where, and I had just worked 17 hours on an emergency for a client, so I really didnt want to get stuck so I kept driving. Turns out the mada wasn't shifting out of third gear. 75MPH was around 3500 RPM (approx), and I couldn't get it to downshift or up shift from this point. I drove it all the way to within a few miles of my house, stopped the car, restarted it and all is well again. Anyone have any idea why shutting the car off in neutral while rolling could have caused this?? Do you think it just tripped up the computer?? I did not get a AT Warning light, and I did notice that the tranny temp would increase when I was going slower (as expected). What do you guys think?

Sounds to me like you might have confused the computer when you shut the vehicle off and then started it while it was moving. Just a guess, though.
I agree. The transmission went into Fail Safe mode. It does that if some of the sensors look wrong. It locks it in that mode so you can get home. When you shut off the engine rolling and restarted it the transmission computer saw unusual sensor readings and went Fail Safe.

Don't shut off the engine while the truck is moving and you should not have that problem. It could be a bug on the vehicle but 99.99% of the driver would not do it since you would lose the power steering, brakes and gear control (transmission).

Just my $0.02.

As far as the nav, it is like any other computer, sometimes you need to "reboot" :comp26: UNIX is the exception.

I had this happen to me once as well. Solved it the same way. Sometimes I hear a small sound coming from the inside the radio when I change stations using the knobs, almost like an small electrical discharge or a spark somewhere inside. Doesn't seem to happen all the time or have any affect, but it's a bit wierd.
