I can't get my transmission and alternator to work at the same time. If the transmission works fine the Alternator will not charge the battery. I the alternator works I have problems with the transmission not catching or shifting into gear correctly. What would cause this problem? I have had the Transmission rebuilt and replaced the alternator, starter and battery. Any suggestions and/or tips are welcome.

Re: transmission and alternator Complications
Just a suggestion/tip. Have you checked to see if the wires going to/from the alternator and transmission run in the same harness. And if they do, maybe they are contacting each other (bare) maybe even the ground wire in the harness became partially disconnected. Hope this can help to solve the problem, or at least elliminate one more reason that might cause the problem. Best wishes.

Voltage regulator is located in the alternator. You do not have a speedo cable it is a sensor located on the transmission above the passenger CV shaft. There is a revised alternator for your van along with a PCM flash upgrade. You might have to take it to a dealer to get the flash done.
Your alternator is starting to go out, or the drive belt could be some what loose, you still have some time if it's the alternator before you have to replace it, (gives you time till pay day),but when the light stay on, needs to be change out or your car will die out, due to no elec, power, and will run only till your battery drains.
You need to check your belt tensioner and serpentine belt for slack and listen for any whining noise. The two events of power steering not working and the battery light not working may be related if the belt is slipping.
The slipping on the alternator will also cause the transmission not to shift properly either since it requires a specific amount of voltage in order to shift properly.
If the belt is fine then check the battery terminals for the proper voltage. Take a multimeter to the terminals with the car off and you should get 12.5V, then start the car and let it idle and you should get 14.4V at the terminal. If either of those numbers are off (or both) then you have a failing alternator and/or battery.
It sounds like the alternator belt or the alternator is going bad. The squealing sound was probably the alternator belt. the alternator belt might need to get tightened or replaced or you may need a new alternator. The alternator keeps the battery charged. When the alternator goes bad the battery can not be recharged. You also should keep the power steering fluid up to par or the power steering will go bad on you.
