You have two options: 1) remove the negative cable for about 5 minutes. 2) you can remove your main relay/fuse. Good Luck

Now, I'm not saying this is a fact, but my TH700R4 trans did that very thing, wouldn't come out of third. And with no 3rd it won't go to overdrive. I rebuilt the trans and found the overdrive drum was all scarred and caused the limp home thing to happen, third gear was as high as it would go. I suggest you have the trans checked out by a professional trans shop. As for it being a bear to start, that's a faulty temperature sensor. If it's not functioning, the computer doesn't know to put it into cold start mode, which increases the throttle speed and puts more fuel in the engine for starting when cold. Like a automatic choke system in earlier vehicles.

Yeah Ron, the flap that covers the heater core is open and when you're moving the air is pushed over the heater core and into the cab your in. Possibly just a vacuum line of that controls said flap. Check all vacuum lines for good proper connection to these flaps because all of them are vacuum actuated.
