Have you had the system checked and the codes pulled? If so and nothing was found,you can bypass each alarm trigger one at a time. If you have the patience, do this yourself and park the car where it happens. If the alarm stopsgoing off wrong,you have found the trigger and/or circuit setting it off. Sometimes this is what it takes because the system is operating in it's parameters and will not set a code? Good Luck.

Why don't you start by getting the correct linkage. Maybe the tranny you replace is not exactly the same one. No difficult to replace, some of them have adjustments so maybe you might be able to get away with it, by adjusting it properly. Ensure the tranny is in the park position when adjusting, if properly adjusted, all the other gear shift should fall in place.

At one point the door was lock from the in side and then closed and then unlocked with alarm, try un-locking it from the drivers door, then from the in side push the un-lock button and then close the drivers door. U should have no problems with it, but they do say that putting the key in the ignition and then do what you would like starting it but don't and do it 2 times and then start it will tell the alarm that it is not stolen.

Do u know that key less entry code to your drivers door?
Let me know if you would like your code that is if you don't know where to look.

I had same problem on my 2002 explorer. Its either the computer module, or the electric solenoid on the transfer case. In my case it was both. The computer module I had done twice in 14 months.
