Some info for you;
"..My AOD works fine in Park, Reverse, and Neutral, and will move forward in OD, D, and Low, but is always in first gear, what could cause this?
There are a few common causes for this. The first is a disconnected or missing TV linkage. If the TV linkage is disconnected the transmission should default to full TV pressure which will make the transmission shift as if it were at Wide Open Throttle all the time. It is also possible that the TV valve in the valve body is stuck in the high pressure position. The easiest way to see if this is the case is to perform a TV pressure test as shown on our TV Linkage Adjustment Page.
Keep in mind when installing the Lokar TV cable with a carburetor, or when making your own TV linkage it is possible to push the TV valve in further than the factory cable allowed. If you are using a valve body with some mileage on it there may be enough of a ridge from the original range of travel to cause the TV valve to get stuck when it travels past the ridge.
You could also have a stuck governor, or a stuck 1-2 shift valve. If the governor is sticking it will cause a delayed, or no upshift, depending on how bad the condition causing the sticking is. If the 1-2 shift valve is stuck, and will not stroke, the transmission will not shift out of first gear.
I just put an 85 AOD transmission in a 1995 F150. My linkage is correct and I have Park, Reverse, and Neutral, but when I go to Drive, 2, or 1, it wont shift out of first gear. What should I do? There was a plug on top of the transmission when I pulled it out of the 85 Ford, what does that do?
The plug on the top of the transmission is the backup lamp and neutral safety switch. It sounds like you don't have a TV cable hooked to the transmission. If the TV cable is not connected the transmission will default to full TV pressure. If TV pressure is full shifts will only occur at the wide open throttle shift point, which is usually around 4900 RPM. This means that even at light throttle you would have to get to 4900 RPM to get a 1-2 shift. If you do have the TV linkage connected, you will need to put a pressure gauge on the TV port to make sure the TV pressure varies properly with throttle position..."

what Voltage do you read batty w/engine running? from your posts, you appear to be knowledgeable about testing, so pls forgive me for asking, but am cur about how this turns out...I have info Links on testing Ford/etc charging/batty systems in my site
a fuse link is installed in the wiring between the battery and the alternator. If the battery is shorted, the fuse link is melted, protecting the alternator.

i have had that clock spring problem and have had t fixed 1-3 years ago but not my airbag light is flashing again
around 4-5 times
and when i shut off the ignition after driving there is an audible alarm that beeps several times then repeates itseld like 3 times or so. it is a different sounding alarm than door ajar or seat belt unfastented...
what do you think friend?

You need to get a good count of the flashes and beeps
Here ya go on the test;
The air bag diagnostic monitor illuminates the air bag indicator for approximately six seconds when the key is in RUN and then turns the indicator off. This shows that the air bag indicator is operational. If the air bag indicator does not illuminate or the indicator stays on or flashes at any time, a fault has been detected by the air bag diagnostic monitor.
* Diagnostic trouble codes may not be displayed for approximately 30 seconds after the key is placed in RUN. This is the amount of time the air bag diagnostic monitor requires to perform all tests and verify system faults, if present.
* Each diagnostic trouble code (a series of flashes and pauses of the air bag indicator) represents a two-digit number. Each diagnostic trouble code is always displayed at least twice. For example, a diagnostic trouble code 32 is displayed as three flashes, followed by a one-second pause, then two flashes, followed by a three-second pause.
* If a system fault is present and the air bag indicator is malfunctioning, an audible tone will be heard, indicating that system service is required. The tone is a series of five sets of five beeps. This does not indicate a diagnostic trouble code 55. If the tone is heard, the air bag indicator is inoperative and a system fault that requires service is present.
CAUTION: The thermal fuse does not blow (open) because of excessive current flowing through it. DO NOT attempt to jumper out the thermal fuse with a circuit breaker or any other type of fuse.
* If a fault exists that makes unwanted air bag deployment possible, the air bag diagnostic monitor has an internal thermal fuse that will blow (open) automatically. This removes all power to the air bag deployment circuit.
* The air bag indicator will flash the appropriate diagnostic trouble code to indicate the suspect circuit. If the indicator is malfunctioning the tone will be heard.
* Diagnostic trouble codes are prioritized numerically so if two or more different faults occur at the same time, the fault having the highest priority will be displayed first. After that fault has been corrected, the next highest priority fault will be displayed.
* The air bag diagnostic monitor includes an internal backup power supply. This feature provides sufficient backup power to deploy the air bag in the event the battery or battery cables are damaged in an accident before safing and primary crash sensors close. The backup power supply will deplete its stored energy approximately one minute after the positive battery cable is disconnected.

Anyone have some advice. I have a 95 Bronco XL (125,000 miles)with a 351 consistantly gets 15 to 16 MPG. I have a 96 XLT (115,000 miles) with a 351 that will not get over 13 MPG, new irridium plugs, new wires, cap and rotor, timing is dead on, new egr. no trouble codes, starts first crank everytime. Any ideas ?

I replied, but apparently the Admin here del my post ...
So, maybe he'll give you info.
btw, I did write that :
believe it is mostly due to the weight difference between the XL and XLT models; XLT has pw, console, running boards, more trim with more insulation, electr. Xfer case module & motor, etc. Even though the trim panels and headliner don't seem to weigh much, it all adds up.
We started with our 96 XL, bought new; & installed pw, pdl, mil/police style push bar, nerf bars, Tuffy console, etc and went from rural driving 15 mpg down to about 14.
Other than wt. check tire pressures monthly and try yo reduce cargo weight.

i have a 94 Ford Bronco and i am thinking about going from factory single exhaust to a flow master dual exhaust system. thenking about having it installed by midas or meineke who i am sure will cut the pipe and not run it from the manifold. will i still get better MPG and a little extra power is what i am concerned about if it is done this way, or should i go about doing this a different way. i love my bronco and have decided to put a little money into it to help it useful life. it is the easiest truck i have ever parked or driven for that matter. i am also having trouble with the ac unit. when turn it on the truck overheats do i need a new water bottle or what should i be looking for. any help will be appreciated. thankx
